The document discusses different types of erosion and their effects on landscapes. It describes three main agents of erosion - water, wind, and glacial ice - and how each leaves distinct sediment patterns. Water erosion in streams is detailed, explaining how velocity, bends, and sediment size impact transportation and deposition. Glacial erosion is also outlined, noting how glaciers carve U-shaped valleys and deposit unsorted sediments.
