How do glaciers shape landscapes?

Glaciers shape landscapes through processes of erosion, transportation, and deposition. As glaciers move, they scrape and carve the underlying rock, creating landforms such as U-shaped valleys and fjords. They also transport debris, known as moraine, which is deposited as the ice melts. Glacial meltwater further shapes the land by creating rivers and depositing sediments. Over thousands of years, glaciers have sculpted iconic landscapes, such as the Yosemite Valley and the Great Lakes, leaving a lasting impact on the environment.
