how do glaciers shape the landscape

As the ice blocks melted, they left behind depressions in the landscape. Background Information: ~ Glaciers are large masses of snow and ice that move slowly downhill due to its weight. As they slide downhill, they carve deep, U-shaped valleys, sharp peaks, and steep ridges. This can happen in a number of ways, including downward creep of the glacier ice into the sediment, freezing of water in sediments to the base of the glacier, and squishing the sediment around beneath the weight of the ice. How Glaciers Shape the Land As glaciers pass over an area, they help shape its features, creating a variety of land forms by means of erosion and by transporting and depositing rock debris. A valley glacier will leave a valley much deeper, as it erodes the underlying surface with plucking and abrasion. WHAT ARE GLACIERS ? Weathering is the break down of rock in situ (in the place where it is). Definitions of some key words used can be found below. Read more. Downhill. All glaciers begin with snow—and a lot of it.
