This document describes different landforms caused by various agents of gradation and erosion. It lists five topographies shaped by running water, wind, glaciers, ground water, and sea water. For each topography, it identifies the responsible agent and their erosional processes. It then lists the characteristic erosional and depositional landforms that result from the actions of each agent. The document serves as a reference for the landforms created by fluvial, desert, glacial, karst and marine processes.
