Location Geographic LOCATION: Click box for more information Tectonic Location Tectonic Location : No tectonic plates on Mars Click box for more information Mars Tharsis Volcanic Region Olympus Mons

Geographic Location Geographic Location : Located in the northern part of planet Mars Part of the Tharsis Region on Mars Which contains several other huge volcanoes Olympus Mons is the largest volcano in the solar system At 27 km high and 600 km across

Tectonic Location Tectonic Location: Mars has no tectonic plates that move horizontally There is a possibility of vertical crust movement Hot lava would push upward through the crust

Age Extinct Volcano Age determination of some of its lava flows show it is older than 200 million years Crater counts show that some regions of he volcano are only 2 million years old.

Force & Rock Cycle Force Both a constructive & destructive force Constructive: creates igneous extrusive rock (A) Destructive: weathering & erosion of surface over time (B) Rock Cycle Shield Volcano that creates igneous extrusive rock (A) Weathering & erosion while volcano is dormant (B) A B

Formation Shield Volcano Shield Volcano with gradual slopes like the Hawaiian Island volcanoes Also formed by a hot spot like Hawaii Large size 3 times the size of Mt Everest due to no tectonic plates on Mars The hot spot keeps feeding the same volcano Mars’ gravity is 1/3 our gravity Its crust is also thicker and stronger Therefore the mass of the volcano doesn’t cause it to sink into the crust Comparison of Olympus Mons to Mt. Everest Gradual slopes

Composition Rock Type Made of igneous extrusive rocks Probably basalt or basaltic andesite Likely a similar composition to Hawaiian volcanoes Scarp Feature Scarp or steep slope surrounds the edge of the volcano Scarp is up to 4 miles high. Lava flows drape over the scarp in places Summit Caldera a composite of up to 7 circular depressions miles across Created from different volcanic eruptions

The Future Olympus Mons is considered to be extinct However, eruptions have occurred as recently as 2 million years It is possible that Olympus Mons could erupt in the future Weathering & erosion will continue to affect Olympus Mons If Olympus Mons became active again over a period of time: –enough gases could be released to warm the atmosphere –This could produce water again on the surface of Mars
