Document Summary
2min video due march 6 (electronic submission) Moon project due march 8 (electronic submission) Rotation period: 243d in one rotation on its axis. Sun rises in west and sets in east. Only has two northern and southern convection cells since rotation is so slow. 400 degrees celsius as result from the greenhouse effect. Relatively flat: different type of plate tectonics than earth. 500m years as surface of venus has only 15% the number of craters as the lunar maria. Undergoes flake tectonics where convection is much more intense and surfaces brakes into flakes. Low pressure: water essentially evaporates right away. Bifurcation of lowlands and highlands on mars between two hemispheres. Mars has very thick crust: no plate tectonics happening as far as we know.
