Here's why:
* Slow Movement: Glaciers are massive bodies of ice that slowly flow downhill due to gravity. This movement is incredibly slow, often only a few inches or feet per day, but over thousands of years, they can carve out huge valleys and shape the landscape.
* Chiseling Action: As glaciers move, they pick up rocks and sediment, which act like sandpaper, grinding and eroding the bedrock beneath them. This process, called glacial erosion, creates distinctive features like U-shaped valleys, cirques, and moraines.
