Energy considerations in geomorphic systems • the systems concept in viewing planets • energy considerations in the Earth system - Earth's internal heat: driving uplift - Solar radiation: driving the hydrologic cycle and wind - chemical potentials (driving weathering) • energy considerations on other planets STUDENT PRESENTATION: Evidence for mantle plumes on Venus. STUDENT PRESENTATION: Dating meteor impacts on the Moon. STUDENT PRESENTATION: Why are Martian mountains and scarps so high?
• What does it take to create a global catastrophe? (Sudbury example; lunar maria) STUDENT PRESENTATION: Gusev Crater on Mars. The Effects of Wind • causes of wind • turbulence in wind • sand dunes and cross beds STUDENT PRESENTATION: The Martian atmosphere and dust storms.
