A glacier trough is also known as a U-shaped valley and is formed when a glacier passes through it. The glacier erodes the bottom of the valley through abrasion, and the sides of the valley through freeze-thaw weathering. It wears away the softer rock but when it gets to the harder, tougher rock it can't erode it to give the glacial trough its shape. Hope this helps!
What else can I help you with?
How glacial spillways are formed?
Glacial spillways are formed when meltwater from a retreating glacier creates a pathway through moraines or other glacial deposits. As the glacier retreats, the trapped water is released, carving out a channel that can carry large volumes of water downstream. These spillways are important for draining glacial lakes and preventing catastrophic flooding.
What is the long hill formed by glacial drift?
A drumlin is a long, narrow hill formed by glacial drift. Drumlins are typically elongated in the direction of glacier movement and have a smoothed, rounded shape.
Is a moraine formed by glacial deposition?
Yes, a moraine is formed by glacial deposition. It is a landform made up of unsorted rock material (till) that has been transported and deposited by a glacier as it moves and melts.
What are some features formed by glacial deposition?
Some features formed by glacial deposition include moraines (ridges of till), drumlins (elongated hills), eskers (sinuous ridges of sand and gravel), and kettles (depressions formed by melting ice blocks).
Is a cirque the result of erosion or deposition?
A cirque, also known as a Cwm or Corrie, is a feature of glacial erosion, formed in a mountainside.

What is a glacial Areté?

What shape valley does a glacier leave?
