Landforms Of Glacial Erosion: U-Shaped Valleys Flashcards
1
Q
What does a u-shaped valley have?
A
A wide, flat floor and steep sides
2
Q
How is it formed?
A
When a glacier moves out of a cirque and down the mountain, it follows the easiest route possible. This route is often a V-shaped valley. The glacier uses plucking and abrasion to widen and deepen the valley, changing it to a U-shaped valley.
