This document discusses weathering, erosion, and deposition processes that shape the Earth's surface. It explains that weathering breaks down rock through physical or chemical means. Erosion then transports weathered material, which is eventually deposited elsewhere. The main agents of erosion are water, wind, ice, and gravity. Glaciers in particular played a major role in shaping landscapes like those in New York State. The document also examines how climate, rock type, and other geologic factors influence landscape development over time.
