How Do Glaciers Shape the Land
Measuring glacier change

Glaciers gain mass through snowfall and lose mass through melting and sublimation (when water evaporates directly from solid ice). Glaciers that terminate in a lake or the ocean also lose mass through iceberg calving.

How did glaciers change North America?

Glaciers changed many landscapes, leaving behind waterfalls and moraines, which are very rocky landscapes created by glacial debris. They created places that had U-shapes, or valleys. Valleys have very steep, high land ranges with flat land in the middle. They are very common in North America and northern Europe.

How do wind and glaciers abrade rock?

Wind abrades rock by sandblasting, this is the process in which wind causes the blowing of millions of grains of sand, which bumps across the surface of rocks’ surface. As glaciers move forwad, the material that they picked up scratch and abrade the rock and soil underneath the glacier, which causes erosion.
