(1) What are the two main energy sources affecting earth? How do mountains interact with both of these?
(2) What are the three main types of plate margins (plate boundaries)?
(3) Does the nature of the rock types and processes change depending on whether ocean crust or continent is involved with the plate margin (boundary)?
(4) What is the hydrosphere... and what is the hydrologic cycle? What drives the hydrologic cycle (i.e. what energy)?
