Features of Mars' Motion Period of a day is 24.6 hours Tilt angle of rotation axis is 24 degrees: This means Mars has seasons
Mars' Interior Small, Cool, Slightly Iron Rich Core
Mars' Surface Features Olympus Mons: Shield volcano, Largest mountain in solar system Valles Mariners: Enormous valley, runs along equator Polar Icecaps: Frozen water and Carbon Dioxide Evidence of past water flow Red dust is Iron Oxide (rust)
Mars' Geologic Activity Northern Hemisphere: More Volcanism Southern Hemisphere: More Impact Craters Plate Tectonics: Formation of plates, cooled too quickly
