This document discusses various processes of erosion and deposition. It describes five main agents that cause erosion: gravity, glaciers, wind, running water, and ocean waves. Each agent breaks down and transports material, then deposits sediments in new locations to form landforms like moraines, drumlins, deltas, and beaches. Gravity causes rapid mass movement or slow creeping. Glaciers carry debris and leave piles of debris called moraines. Wind erodes loose material from deserts and fields, depositing loess and dunes. Running water is a major cause, forming canyons and depositing material in river deltas and flood plains. Ocean waves erode shorelines, depositing beaches, spits, and barrier
