Glacial erosion can form various landforms like cirques, arêtes, and valleys. As glaciers move, they pick up rocks and debris, which can carve out shallow grooves known as striations on the underlying rock. When the glacier retreats, it leaves behind moraines made up of this debris.
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.

How was the dry falls formed?
The dry falls were formed by glacial activity
What is a soil formed by?
Windblown glacial sediments.
What are the types of features that form from glacial erosion?
Glacial Erosion formed Yosemite Valley and the Sierra Nevada
What is most often formed by glacial action?

How is plateaus formed?
its formed by eroion on the sides of sedimentary rock
How was long island formed?
It was caused by deposition. Of glacial moraine.

How was caves formed?
The Maquoketa caves in Iowa were formed through years of natural non-glacial erosion.
