How do a valley glacier form?
Continental and valley glaciers both develop in regions where there is constant snowfall and freezing temperatures throughout the year. Both types of glaciers move at a very slow pace.
How can you tell whether valley glaciers once existed in a mountainous region?
Look at the shape of the valleys. If they are V-shaped there were no valley glaciers; if they are U-shaped there were.
What agent of erosion most likely produced this valley's shape?
When the glacier is moving down the side of the valley it scrapes of the rocks. The grinding changes the shape of the valley so that it is rounded.
Explain how a fjord is formed?
The fjords are surrounded by rugged mountains. We can find them on the shoreline in Labrador. They are formed by glaciers that sculpted the valley's from a <<v>> shape to a <<u>> shape.
How can you tell if a valley was formed by a glacier?
The valley has a U-shape or rounded bottom.
How do glaciers make valleys?
The glaciers rubs against the land form which changes the land form into a U shape valley this works because the ice is so packed it pushes any land as in dirt sand and minerals out the way creating the valley
What are 3 ways a glacier can change the shape of land?
Glaciers can pick up and drop boulders Glaciers dig furrows in the ground where they have passed Glaciers are able to move mountains out of their way
What is the movement of a glacier?
As a glacier moves through a valley, it digs deep into the walls and floor . A once-narrow valley that had a V shape becomes wider. As a glacier moves through, the valley becomes U shape .
How can mountains tell us what glaciers existed at the beginning of time?
At the beginning of time there were no mountains or glaciers, there were also no planets or stars. Mountains can tell us where glaciers existed by the shape of the valleys between them, a "U" shaped valley usually means a glacier once flowed down it.
What are 2 ways glaciers helped shape the northeast?
As the glaciers receded with gravity pulling them downstream they created our valleys. Where I live in the Northeast part of the US we are in Wyoming Valley in Pennsylvania.
How does moving ice change the shape of the earth?
Erosion. Glaciers also contain rock fragments, which act as an abrasive.
How do plate tectonics affect the ocean floor?
They change its size and shape.
