AST-1002 Chapter Notes - Chapter 7: Solar Time, Permafrost, Regolith
Document Summary
Northern waste/ northern devastation - relatively young, crater-free terrain surrounding the. Southern highlands- older, cratered terrain in the martian southern hemisphere. Hot-spot volcanism - the creation of volcanoes on a planet"s surface caused by a reservoir of hot magma in the planet"s mantle under a thin part of the crust. Caldera - the crater at the summit of a volcano. Dust devils - heat from the planet"s surface warms the air and sometimes creates whirlwinds. Venus has the densest atmosphere of all of the solar system"s terrestrial bodies. Earth obviously has water, and w/ the phoenix and the mars odyssey missions, we have plenty of evidence that mars has water on it, although most of it is in a frozen state. You should be able to identify similarities and difference between the volcanic features of earth, About 27% of the earth"s surface is continental crust that rises above the ocean floors by 4-6km.
