work of glaciers and wind class 7

A mass of ice that arises from years of snow adding up. The glacier ended at the ocean where huge chunks of ice fell into the sea.

• wind

• water

• glacier

A valley that is rounded at the bottom; formed and given its characteristic shape by a glacier that once inhabited it. There are many U-shaped valleys in Alaska.

• u- valley

• v-valley

• o- valley

what is the difference between u- valley and v- valley?

• u is formed by ice while v is formed by water

• u is formed by mud while v is formed by rocks

• u is formed by water while v is formed by ice

Formed between mountains so that it is shaped like a wedge, or a giant U. When the ice melts, a U-shaped valley Opens in modal popup window remains.

• alpine glacier

• valley glacier

• continental glacier

Formed on the tops and sides of tall mountains.

• continental glacier

• valley glacier

• alpine glacier

Formed during ice ages. These can cover thousands of square miles. Antarctica and Greenland have these ice sheets.

• valley glacier

• Continental glacier

• alpine glacier

WHICH OF THESE ANSWERS IS A TYPE OF GLACIER'S MOVEMENT: MORE THAN ONE ANSWER

• stays until wind breaks it down

• the glacier grows, it becomes heavier and heavier. At some point its mass is so great that it begins to slide, slowly but forcefully, down the mountain.

• it breaks down by itself and go to the river or ocean

• a glacier moves is by crushing itself.

The mass of earth and ice pushed to the front or side of a moving glacier. Most of the high ports in northern Long Island in New York State are parts of an old moraine.

• moraine

• glacier

• snow mountains

which one is less dramatic

• wind

• glacier crushing

Erosion by wind can cause immense, choking dust clouds. Dry weather and reduction in ground cover can cause dangerous loss of soil to wind.

• false

• true
