Glaciers shape the land through processes such as erosion, transportation, and deposition. As glaciers move, they pick up rocks and sediment along the way. The weight and pressure of the ice cause the glacier to grind against the land, carving out valleys, cirques, and fjords. When the glacier melts, it deposits the material it has picked up, forming features like moraines and drumlins. Over time, glaciers can drastically alter landscapes, creating unique and striking landforms.
