http://www.mars.nasa2/data.html http://www.nasa.mars.com
SPECIFIC RESEARCH DISCOVERIES:
We discovered that there are more possibilities
and evidence for there to be techtonic plates
on Mars. Such as volcanoes and faults and trenches.
These all support the theory of volcanoes. Also
there looks like there is a hot spot just South
East of Olympus Mons the biggest volcano in
the Universe. We also think that Olympus Mons
itself is a hotspot because of its massive plume
and base. Its just that the plate is not moving.
SUMMARY OF FINDINGS:
We found many features about magmnitism. One
there are polar ice caps on Mars there is a
North and South. We found that it takes the
same amount of time to revolve aruond the axis
as it does on Earth. 24=1 day on Earth and 24=1
day on Mars.
Olympus Mons is a shield volcano We determined
that because it had many Flanks and fissures
all over it. It has a flat dome, it had steep
sides, and it is very tall. This specific characteristic
did not support our theory because the volcano
could have been occured at a convergent boundry
or it could have been made by a hotspot. We
also found a trench not far away. This charachteristic
totally supports our theory because the only
thing that forms a trendh is a convergent boundry.
MAN WERE GOOD!!!!! When one plate slides under
the other. This means if there is a trench there
is a convergent boundry. Which means there is
plate movement. Which means there is a plate
boundry. Man Patrick put which in here a lot.
One more characteristic is that we found a chain
of active dormant and exticted volcanoes. But
these were in a stright line. It is most obvious
that this was formed by a hot spot but there
is movement above the candle so that means there
is a plate above it . This plate is flanking
with Olympus Mons. So in conclusion we our group
of Patrick Omar and Joe answere that yes there
are plate techtonics on Mars es just dont know
how many. We have many pictures but we cant
find a way to get them on here.

NAMES OF MARTIAN SITES INVESTIGATED:
The Martian sites investigated were Erebus Montes,
Ulysses Patera, Hibis Montes, Nigral Vallis,
and three volcanoes by Olympus Mons.
SPECIFIC RESEARCH DISCOVERIES:
On Erebus Montes, a rift valley seemed to have
been formed by a divergent boundary. The formation
was composed of long linear valleys of an irregular
shape. A low elevated split in the crust was
present, while the rift continued for miles.
At Ulysses Patera, a cinder cone volcano was
observed, encircled by a circular land mass.
The sides had several lava imprints flowing
outwards, on the brood sloping sides, of the
dome shaped volcano. Hibis Montes, the next
location analized, had a mountain. The mountain
had a high elevation with small groups of ridges
and peaks. Tiny imprints of lava flows drained
down from the sides, that confirms that volcanic
eruptions aided in it's formation. At Nigral
Vallis, a trench was found with a large elevation
difference. The center had a subduction zone,
where the two plates met, which was steep. The
left end of the trench was connected as you
moved further along. The last features examined
were the four volcanoes by Olympus Mons. This
seemed to be a result of a hotspot, while the
plate moved southwest.
SUMMARY OF FINDINGS:
The locations observed were the rift valley,
volcano, mountain, trench, and a hotspot. Each
of these features have a great possibility of
being formed by plate tectonics. All the features
had detailed characteristics with a pattern.
There were to evidence seen, disproving the
theory of plate tectonics on Mars. This concludes
that there are plate tectonics on Mars.

Tharsis Montes: Arsia Mons, Parvonis Mons, and
Ascraeus Mons
Olympus Mons
Valles Marineris
SPECIFIC RESEARCH DISCOVERIES:
Arsia Mons:
The circular lines on Arsia Mons are getting
smaller as it extends outward. There is a huge
valley near this particular mons. This particular
mons is a shield volcano.
Parvonis Mons:
The contour lines on Parvonis Mons is getting
smaller. The crater at the top is much larger
than the one in Arsia Mons. This Mons is also
a Shield volcano. Pavonis Mons is following
Arsia Mons in a pattern-like formation.
Ascraeus Mons:
Ascraeus Mons is at the top of the trio of this
particular volcano chain, following the Arsia
and Parvonis Mons. It also is the biggest of
the three volcanos. Most likely Ascraeus Mons
is an extinct volcano but was once the center
of a hot spot.
Olympus Mons:
Olympus Mons is the largest volcano on Mars.
It is a very flat volcano but has a fairly gentle
surface. Also Olympus Mons has rough, crinkly
patches around it. There is a humongous crater
at the top of the volcano. It als has the characteristics
of a shield volcano. This volcano is an active
one.
Tharsis Montes:
The mountains in the Tharsis region resemble
a pattern like the one in the Empereor Seamounts
on earth. They also formed a pattern showing
either a hot spot or a boundary line. All of
the volcanos in the Tharsis region are shield
volcanos. These mountains are also bordered
by a trench called Vales Marineras.
Valles Marineris:
It is a low valley which extends over most of
the of the western hemisphere of Mars. Valles
Marineris was created by a diverging boundary.
Three volcanos surround it: Arsia Mons, Parvonis
Mons, and Ascraeus Mons, which were caused by
a diverging boundary. Also the Syria Planum,
Lunae Planum, Sinai Planum, Solis planum are
mostly to the South of the valles.
SUMMARY OF FINDINGS:
All of the mons in the Tharsis Region appear
to be shield volcanos because shield volcanos
are low, broad, dome-shaped types of volcanos
which are identical to the volcanos in the Tharsis
Region. Shild volcanos happen along diverging
boundaries or a hot spot which can only mean
platetectonics occur on Mars. Also, the circular
lines on Arsia Mons are getting smaller which
means the land is rising and for the land to
be rising there has to be movement occurring
on the plates Arsia Mons is sitting on. From
the following information gathered, we have
concluded that platetectonics occur on Mars.

SPECIFIC RESEARCH DISCOVERIES:
Different landforms and craters. Areas that
have no particular names.
SUMMARY OF FINDINGS:
After closely studying areas that indicate signs
of compression, I have decided that are plate
tectonics on Mars. My conclusion is based on
only what I studied. From the data that I collected
off of the internet, I have discovered many
flat surfaces with rising elevations on each
side. This is an indication of compression.
There are also stress marks located throughout
Mars that are mainly found aorund mountains
and other such landforms. On one particular
site, I found an area where there are landforms
that seem to be moving all in the same direction.
They are small ripples or chains of mountains
that are moving in the same pattern. This is
a large indication that there is compression
on Mars. When ripples or hills are formed that
move in the same direction and that have a lower
elevation in between each of them, this is most
likely a sign of compression. Iresearched most
of the different locations on Mars. That is
why I have no actual site. I have studied all
of Mars and I have found definite indication
of compression.

THERE ARE NO CANALS ON MARS!
Conclusion:
My group and I concluded that Mars only has
plate tectonics in certain areas where charaterics
of plate tectonics are spotted. The volcanoes
formed on Mars, which resemble those of Hawaii,
are from hot spots under the Martian crust.
They are built from magma chambers under the
crust of Mars. Both the plains and the volcanoes
are cut by a graben indicating that there is
tectonic activity on Mars, in some places, subsequent
to where the plains have been placed on Mars.
Hot spots do exists on Mars.
The flows of the volcanoes on Mars are much
longer than the ones on Earth. Convection occur
on Mars where the hot material flows upward
and cooler material sink into the interior.
This is caused by creating a large-scale circulation
known as mantle convection which happens on
Mars. This type of mantle flow produces plate
tectonics on Earth. In 1988, scientists studied
a strike-slip fault it was probably caused by
a "Marsquake" that proved that there
was plate tectonics on Mars.
The northern half of Mars has a less cratered
surface believed to consist of volcanic flows.
Two major past volcanic activity have been identified:
the Elysium Plateau and the Tharsis bulge. Some
of the solar system's largest volcanoes occur
on Tharsis. No definite evidence exists of any
current volcanic activity anywhere on the plate.
It seems that volcanic activty has ended but
we see evidence of enormous volcano remnants
on the planet. The absence of a magnetic field
and the absence plate tectonics in some places
suggests that Mars does not have hot, molten
core. Little is known interior of Mars. The
palnets low density indicates that Mars cannot
have an extensive metallic core. Any core that
is present is probably not fluid, because Mars
does not have a measurable magnetic field.

Nirgral Vallis
Kasei Vallis
SPECIFIC RESEARCH DISCOVERIES:
On all of these sites I have found different
specific features such as:
In Valleys of Thaumasia I have discovered Rift
Valleys, Craters, Elevation Differences, Evidense
of Earthquakes, Fault lines, and Divergent Boundaries.
In the Nirgral Vallis I have also found Rift
Valleys, Craters, Flat Surfaces (some)and Volcanic
Cones. And Finally on the Kasei Vallis which
was also much like the other two sites which
had Craters, Faults, Rifts, Volcanic Cones,
Valleys, Divergent Boundaries, and Elevation
Differences.
SUMMARY OF FINDINGS:
In my opinion on this project I have found EVIDENCE
OF TECTONICS in all of the sites that I have
researched, I have proven that there are Plate
techtonics on Mars.
I believe that there are Plate Techtonics on
Mars because I have found extensive evidense
that leads me to believe in my conclusion (I
have found evidence that match my characteristics
on Earth). I have found rift valleys, they indicate
extrusions of lava, and volcanos, elevation
differences, they indicate convergent boundaries,
earthquake movement(evidense), this indicates
that there are plates and that they are moving,
valleys, these indicate streams of water and
occurences of erosion, divergent boundaries,
they indicate plate movement away from each
other, craters, these can indicate volcanos
or meteoric activity, fault lines, these indicate
earthquake movement and divergent boundaries,and
volcanic cones, which are the types of volcanos,indicate
volcanos and volcanic activity.
I have concluded that there are Plate Techtonics
on the three sites that I have observed using
this information.
Ashley Mayes
St. Anne School, Houston, Texas
Purpose:
The purpose of this project is to convince my
reader that there ARE plate tectonics on Mars
due to my research. Responsible For:
volcanoes
fallen ash
rocks
At the sites of:
20 degrees North, 135 degrees West-Olympus Mons
and -10 degrees South, 110 degrees West-Tharsis
Montes
Volcanoes
The volcanoes I studied on Mars show that there
are subduction zones. The subduction zones are
"lines" of contact between adjacent
crustal blocks. The presence of volcanoes can
signify convergent and divergent boundaries.
The forming of the volcanoes indicates that
the volcanoes I studied at the two sites on
Mars have ridges supporting their magma flow.
From the hardened lava that surrounds some volcanoes
it shows that there is viscous lava underneath
the surrounding surface (i.e., Olympus Mons).
There have to be subduction zones because of
the ascent of magma. In both Olympus Mons and
Tharsis Montes the lava flow that precedes the
building of a volcano shows some definite similarities
that occur when a volcano is formed in a formed
in a divergent boundary. This theory is only
supported by the appearances of my two sites.
As you can see, a volcano is a hill or mountain
formed around and above vents by accumulation
of erupted materials such as ash or lava flow.
They are usually formed in chains along some
type of subduction zone. As you can also see,
Tharsis Montes is a chain of 3 volcanoes and
if you locate a map of Mars you notice that
there are more volcanoes forming farther along
in a pattern away from Tharsis Montesshowing
there must be a plate boundary in this area.
You could easily hypothesize that the Tharsis
Montes were formed along a major fracture zone
between plates and have now been buried in by
the products of their volcanism. However, the
less linear distributive pattern of volcanoes
in some areas implies the absence of a segmented
lithosphere on Mars. Added to the fact that
I believe there are subduction zones on Mars
that contain volcanoes, you must know another
important fact. Subduction zones generate magma
by melting oceanic crust at the top of a descending
plate, by ocean sediment dragged to great depths,
and by asthenosphere caught between converging
plates, which makes you think, "What makes
the magma on Mars?"
Fallen Ash & Rocks
Since there are volcanoes on Mars there is ash
in the vicinity of these areas. Due to eruptions
of the present and past there is fallen ash
from the volcanoes and there still are remains
of these small particles in the air. What exactly
is fallen ash? Fallen ash is pulverized volcanic
rock that explodes from a vent in minute fragments.
This ash is often composed of rhyolite, dacite,
trachyte, and maybe andesite. The relationship
of ash to plate tectonics is that it shows whether
there are different types rocks that are in
the ash that are found in the plates that lye
underneath. For instance, you may find a sample
of ash from Earth that was found in the general
area of a volcano and it would be composed of
rhyolite, andesite, and some other minute particle
found in the lithosphere. which would signify
plate tectonics. Rocks are believed to be on
Mars. The rocks on Mars may be just like the
Canadian Shield. This means the oldest part
of a major crustal plate that is somehow exposed
and has rocky-like structure. The rocks have
been formed by distinct movements of the plates
I believe are there. Rocks are consolidated
material of an indefinite structure. From different
impressions on Mars you can tell that some type
of rock exists and is constantly engraving into
the outer surface of the planet. The major crustal
plate I believe exists can also be responsible
for other formations that signify the presence
of rocks (i.e., terracing, and the distinct
structure of some flanks on Mars). Ashley

Montes Purpose: The purpose of this project
is to convince my reader that there ARE plate
tectonics on Mars due to my research. Sources:
- Answer: Yes, there are plate tectonics
on Mars. There is a lot of evidence that
prove this. When you look at a picture of
Mars, you can see that there are mountains
and craters or meteors all over the planet.
The mountains alone prove that there are
at least two plates on Mars because mountains
can only be formed by the pushing together
of two or more plates with landmasses on
them. The craters might easily be the tops
of volcanoes. We also know that volcanoes
exist because in one of our recent classes
we did a lab in which we made "volcanoes"
and "mountains" out of cat litter.
Then, we measured the flanks of the litter
mounds and later pictures of real volcanoes
on the computer. One of these was Olympus
Mons, which is a volcano on Mars. The left
flank's measurement is 33 degrees and the
right flank's measurement is 24 degrees.
Natalie's and my observation area was a
rectangle with the following measurements:
latitude-0 , longitude-40 W; latitude-0,
longitude-0; latitude-10 S , longitude-40
W; latitude-10 S, longitude-0
- From what we observed, this area was covered
with mountains and trenches. We also saw
what looked like a valley. These, of course
are all products of plate tectonics. In
conclusion, we know plate tectonics do exist
on Mars because of the physical evidence
that is similar to that which is found on
Earth.

Plate Tectonics on Mars
To answer the question of plate tectonics on
Mars we observed the surface of Mars from latitude
70 degrees North to 70 degrees South and longitude
140 degrees West to 220 degrees East. We concluted
that there was plate tectonics on Mars. We concluded
this because of the information we collected.
Now if you would look at the attached sheet
that supports our conclusion. The orange on
the map represents the mountain formations in
the area we selected. This supports our theory
that there are plate tectonics because of converging
boundries. The green on the map represents the
volcanic terrain in the area that our group
selected. This also supports that there are
diverging boundaries on Mars. The blue line
represents ridges in the area our group chose.
This is another fact that helps support our
conclusion. The last color which is red is representing
the fractures on the area which my group slected.
This fact also supports our conclusion because
fractures are side effects of either a diverging
or converging boundry. This is the evidence
we collected to prove that there are plate tectonics
on Mars.

SPECIFIC RESEARCH DISCOVERIES:
Different landforms and craters. Areas that
have no particular names.
SUMMARY OF FINDINGS:
After closely studying areas that indicate
signs of compression, I have decided that
are plate tectonics on Mars. My conclusion
is based on only what I studied. From the
data that I collected off of the internet,
I have discovered many flat surfaces with
rising elevations on each side. This is an
indication of compression. There are also
stress marks located throughout Mars that
are mainly found aorund mountains and other
such landforms. On one particular site, I
found an area where there are landforms that
seem to be moving all in the same direction.
They are small ripples or chains of mountains
that are moving in the same pattern. This
is a large indication that there is compression
on Mars. When ripples or hills are formed
that move in the same direction and that have
a lower elevation in between each of them,
this is most likely a sign of compression.
Iresearched most of the different locations
on Mars. That is why I have no actual site.
I have studied all of Mars and I have found
definite indication of compression.

SPECIFIC RESEARCH DISCOVERIES:
Iani & Eos Chasma, Oria & Deuteranilus
Colles, Nactis Labyrinth, Protonilus &
Aedois Mensa, Charitum Montes, and Rasei Vallis
SUMMARY OF FINDINGS:
These features are signs of convergent boundries,
such as mountains, trenches,valleys,and other
seperations. The Iani and Eos Chasma is an
area with broken terrain due to the collision
of plates. The Oria and Deuteranilus Colles
are hills by mountains made by the plates
forming mountains. The Nactis Labyrinth is
a pattern of valleys in a mountain system
made by the collision of convergent boundries.
The Protonilus and Aedois Mensa are mesa was
a mountain but was worn away. The Charitum
Montes is a system of mountains made by a
convergent boundry when the plates collide.
The Rosei Vallis is another type of valley
that has been worn away out of the sides of
mountains that were formed by plates colliding.

THERE ARE NO CANALS ON MARS!
Conclusion:
My group and I concluded that Mars only has
plate tectonics in certain areas where charaterics
of plate tectonics are spotted. The volcanoes
formed on Mars, which resemble those of Hawaii,
are from hot spots under the Martian crust.
They are built from magma chambers under the
crust of Mars. Both the plains and the volcanoes
are cut by a graben indicating that there
is tectonic activity on Mars, in some places,
subsequent to where the plains have been placed
on Mars. Hot spots do exists on Mars.
The flows of the volcanoes on Mars are much
longer than the ones on Earth. Convection
occur on Mars where the hot material flows
upward and cooler material sink into the interior.
This is caused by creating a large-scale circulation
known as mantle convection which happens on
Mars. This type of mantle flow produces plate
tectonics on Earth. In 1988, scientists studied
a strike-slip fault it was probably caused
by a "Marsquake" that proved that
there was plate tectonics on Mars.
The northern half of Mars has a less cratered
surface believed to consist of volcanic flows.
Two major past volcanic activity have been
identified: the Elysium Plateau and the Tharsis
bulge. Some of the solar system's largest
volcanoes occur on Tharsis. No definite evidence
exists of any current volcanic activity anywhere
on the plate.
It seems that volcanic activty has ended
but we see evidence of enormous volcano remnants
on the planet. The absence of a magnetic field
and the absence plate tectonics in some places
suggests that Mars does not have hot, molten
core. Little is known interior of Mars. The
palnets low density indicates that Mars cannot
have an extensive metallic core. Any core
that is present is probably not fluid, because
Mars does not have a measurable magnetic field.

NAMES OF MARTIAN SITES INVESTIGATED:
Valley of Thaumasia
Nirgral Vallis
Kasei Vallis
SPECIFIC RESEARCH DISCOVERIES:
On all of these sites I have found different
specific features such as:
In Valleys of Thaumasia I have discovered
Rift Valleys, Craters, Elevation Differences,
Evidense of Earthquakes, Fault lines, and
Divergent Boundaries.
In the Nirgral Vallis I have also found Rift
Valleys, Craters, Flat Surfaces (some)and
Volcanic Cones. And Finally on the Kasei Vallis
which was also much like the other two sites
which had Craters, Faults, Rifts, Volcanic
Cones, Valleys, Divergent Boundaries, and
Elevation Differences.
SUMMARY OF FINDINGS:
In my opinion on this project I have found
EVIDENCE OF TECTONICS in all of the sites
that I have researched, I have proven that
there are Plate techtonics on Mars.
I believe that there are Plate Techtonics
on Mars because I have found extensive evidense
that leads me to believe in my conclusion
(I have found evidence that match my characteristics
on Earth). I have found rift valleys, they
indicate extrusions of lava, and volcanos,
elevation differences, they indicate convergent
boundaries, earthquake movement(evidense),
this indicates that there are plates and that
they are moving, valleys, these indicate streams
of water and occurences of erosion, divergent
boundaries, they indicate plate movement away
from each other, craters, these can indicate
volcanos or meteoric activity, fault lines,
these indicate earthquake movement and divergent
boundaries,and volcanic cones, which are the
types of volcanos,indicate volcanos and volcanic
activity.
I have concluded that there are Plate Techtonics
on the three sites that I have observed using
this information.

Purpose:
The purpose of this project is to convince
my reader that there ARE plate tectonics on
Mars due to my research. Responsible For:
volcanoes
fallen ash
rocks
At the sites of:
20 degrees North, 135 degrees West-Olympus
Mons and -10 degrees South, 110 degrees West-Tharsis
Montes
Volcanoes
The volcanoes I studied on Mars show that
there are subduction zones. The subduction
zones are "lines" of contact between
adjacent crustal blocks. The presence of volcanoes
can signify convergent and divergent boundaries.
The forming of the volcanoes indicates that
the volcanoes I studied at the two sites on
Mars have ridges supporting their magma flow.
From the hardened lava that surrounds some
volcanoes it shows that there is viscous lava
underneath the surrounding surface (i.e.,
Olympus Mons). There have to be subduction
zones because of the ascent of magma. In both
Olympus Mons and Tharsis Montes the lava flow
that precedes the building of a volcano shows
some definite similarities that occur when
a volcano is formed in a formed in a divergent
boundary. This theory is only supported by
the appearances of my two sites. As you can
see, a volcano is a hill or mountain formed
around and above vents by accumulation of
erupted materials such as ash or lava flow.
They are usually formed in chains along some
type of subduction zone. As you can also see,
Tharsis Montes is a chain of 3 volcanoes and
if you locate a map of Mars you notice that
there are more volcanoes forming farther along
in a pattern away from Tharsis Montesshowing
there must be a plate boundary in this area.
You could easily hypothesize that the Tharsis
Montes were formed along a major fracture
zone between plates and have now been buried
in by the products of their volcanism. However,
the less linear distributive pattern of volcanoes
in some areas implies the absence of a segmented
lithosphere on Mars. Added to the fact that
I believe there are subduction zones on Mars
that contain volcanoes, you must know another
important fact. Subduction zones generate
magma by melting oceanic crust at the top
of a descending plate, by ocean sediment dragged
to great depths, and by asthenosphere caught
between converging plates, which makes you
think, "What makes the magma on Mars?"
Fallen Ash & Rocks
Since there are volcanoes on Mars there is
ash in the vicinity of these areas. Due to
eruptions of the present and past there is
fallen ash from the volcanoes and there still
are remains of these small particles in the
air. What exactly is fallen ash? Fallen ash
is pulverized volcanic rock that explodes
from a vent in minute fragments. This ash
is often composed of rhyolite, dacite, trachyte,
and maybe andesite. The relationship of ash
to plate tectonics is that it shows whether
there are different types rocks that are in
the ash that are found in the plates that
lye underneath. For instance, you may find
a sample of ash from Earth that was found
in the general area of a volcano and it would
be composed of rhyolite, andesite, and some
other minute particle found in the lithosphere.
which would signify plate tectonics. Rocks
are believed to be on Mars. The rocks on Mars
may be just like the Canadian Shield. This
means the oldest part of a major crustal plate
that is somehow exposed and has rocky-like
structure. The rocks have been formed by distinct
movements of the plates I believe are there.
Rocks are consolidated material of an indefinite
structure. From different impressions on Mars
you can tell that some type of rock exists
and is constantly engraving into the outer
surface of the planet. The major crustal plate
I believe exists can also be responsible for
other formations that signify the presence
of rocks (i.e., terracing, and the distinct
structure of some flanks on Mars). Ashley
