Crevasses are gaping cracks that form in the upper part of a glacier Why do crevasses form?
Brittle ice breaks as the glacier crosses rough terrain
What kind of glaciers form when ice and snow build up in a mountain valley?
'Alpine' glaciers form.
How much of the earth surface do glaciers cover?
20%
Do earthquakes and glaciers change the earth surface?
yes they do and so do glaciers, hurricanes, tornadoes and many other things
Glaciers weather surface rocks mainly through the process of?
Glaciers weather surface rocks mainly through the process of abrasion. Intermediate earthquakes occur 70 to 300 kilometers below the Earth's surface.
Why are crevasses dangerous?
Crevasses are formed due to tensile forces overcoming the cohesive strength of the ice. They form perpendicular to the principle stress. So depending on what is happening to the Glacier Ice, different types of crevasses can form. Chevron crevasses form from high friction with the valley sides. Transverse crevasses form from extending ice flows. And splaying crevasses form under compressive ice flows. Hope this helps!
What landscape features do glaciers form?
Glaciers can form various landscape features, including U-shaped valleys, cirques, aretes, and moraines. These features are created as glaciers erode and deposit material as they flow over the land.
Explain two reasons why crevasses may form in certain regions of glaciers?
The stuff in your butt that's all crusty and icky.
How a crevasse forms?
crevasses are formed by glaciers creating pressure on the land.
What are two ways in which glaciers erode Earth's surface?
When glaciers form they scrape earth's surface as they advance. Also when glaciers melt it deposits the sediment it eroded from the land creating various land forms.
How do rivers form in ice caves?
Simply melt-water from the surrounding ice, or the surface of the glacier and reaching the cave through crevasses.
How do glaciers form and change the earth's surface?
by gravity, ice, wind, water
Glaciers often form parallel scratches and grooves in bedrock because glaciers?
Drag loose rocks over Earth's surface
Crevasses are gaping cracks that form in the upper part of a glacier Why do crevasses form?
Brittle ice breaks as the glacier crosses rough terrain
Does Neptune have glaciers?
No. Neptune does not have a solid surface for glaciers to be on.
What term describes open fissures in the brittle surface ice of a glacier?
crevasses
Does Saturn have glaciers?
No, it does not. For glaciers you need a solid surface, which Saturn does not have.
