Document Summary
Epsc201 2006 final exam review section 5&6: draw a structural cross-section through the andes. Identify two types of faults on the section and explain their origin. The rockies and andes are the result of subduction of an oceanic plate under a continental plate. In extension environments, there is also mountain formation. Grabens and horsts are formed, and can be up to a thousand meters high. There is a thinning of the continental crust when it is pulled apart, but there is still ridge formation. The fault lines do not go straight downward in extension environments. They seem to go down on an angle. The material responds to stretching differently depending on how ductile it is. If very ductile, the continent will stretch and thin. However, if it is brittle, there will be fault formation: name and explain three criteria for establishing relative ages of rocks.
