GEOG 1111 Study Guide - Midterm Guide: Geomorphology, Oceanic Crust, Landform
Document Summary
Topography elevation changes of the earth"s surface over a given space or distance (ridges and valleys) Uniformitarianism were in the past and will be in the future. Fluvial those developed by flowing liquid water (rivers) Glacial those landforms developed by glacial ice (solid water) Eolian landforms are those developed by wind processes. Internal processes crust, volcanism, mountain building, massive crustal rearrangement (plate tectonics), earthquakes, etc. The material in this layer is in a solid state and consists primarily of iron (fe) and nickel (ni). The top of the layer is about 3200 miles below sea level (bsl), and it is about 760 mi thick. The material in this layer is under less pressure since there is less material on top of it. This causes its melting t to be lower, thus the material is in a liquid/molten state. Also generates most of the earth"s magnetic field.
