Document Summary
Glacial till: the upper non-solid layer of the earth"s mantle. Uppermost mantle: chip in cuesta without a flat top. Relief inversion: the hill of sediment that is left behind when ice melts. Volcanic dike: a moraine that has been deposited at the furthest advance of a glacier (example: conveyor belt) Uppermost mantle: unsorted, deposited directly by melting ice (till makes a moraine) Uppermost mantle: permeation of liquid into the ground, slow process, happens on flatter terrains. Braided stream: waterfalls in glaciers, u-shaped valleys created in glaciers on the edge. Factors influencing infiltration vs overland flow: when an oceanic plate slides underneath a continental plate. Anticline: faults and folds and how they affect the earth. Deposition: when a valley is refilled with sediment, river is raised. Alluvium: the lower portion of the lithosphere, made of solid rock. Overthrust fault: a graph that shows the amount of water in a river (lag, duration, discharge, flood peak, base flow, time)
