Erosion Assignment

This assignment explores the key concepts of erosion and sediment transport through water, ice, and wind. It covers how streams erode their channels and deposit sediment, the types of stream valleys, and the formation of deltas, natural levees, and floodplains. Additionally, we delve into glacial erosion, landscape features formed by glaciers, and the different types of glacial drift. Finally, we examine wind's role in landscape shaping through processes like deflation and abrasion, as well as the resulting landforms.
