Exploring Geology on Earth and Mars Unit 2 By Jad Gaytan

Similarities Volcanoes Mountains Canyons e. formed by rivers m. formed by volcanic activity Polar Caps Dunes Craters e. signs of craters changed by wind/water erosion m. craters are preserved

Difference Water covers 70% of Earth There is no visible sign of water on the Martian surface

Geological Processes Tectonic plates e. constantly moving m. made of one thick plate Volcanism Erosion Creation of craters

Olympus Mons

Craters on the surface of Mars

2.1 Which Feature Came First? Identify major geological features on Mars (find evidence of canyons, channels, etc.) Primary grades – coloring, Master 2.1A Middle grades – Dioramas, storyboards Assessment – Master 2.1B Upper level – age date features using Principles of Superposition and Crosscutting relationship – Master 2.1C

2.2 Modeling Martian Craters Hypothesis – What factors affect the size of a Martian crater? Vary the impactor size Vary the distance of the impactor Any other variable?

2.3 Martian Meteorite Mysteries Compare Martian meteorite with Earth rocks based on infrared emissions Master 2.3A – spectra of Martian rocks Master 2.3B and C – spectra of known minerals from Earth rocks Primary grades – simulation on JPL Arealogy – The Study of Mars

2.4 Soil Sleuthing Compare a local soil sample to a Martian soil simulant Primary grades – color organisms that thrive in the soil
