What is the driving force behind glacial movement?
Once the depth of snow and ice reaches more than 30 to 40 meters, gravity begins to pull the glacier down hill.Also as the glacier melts due to pressure if creates melt water which acts as a lubricant.

What force must you overcome to start an object moving?
Friction. Specifically, static friction. After the object begins to move, it will still be necessary to overcome rolling or sliding friction to keep it in motion.
What effect does friction have on motion?
Friction causes object in motion to slow down. As friction increases, it takes more and more energy for an object to keep its inertia (momentum) and it begins to slow down.

When does the snow and ice that make up glacier begin to move downhill?
Once snow and ice reach more than 30 to 40 meters gravity begins to pull the glacier downhill.I hope I helped you!!! =)
What is the glacial stream in south America?
Snow falls in the accumulation area, usually the part of the glacier with the highest elevation, adding to theglacier'smass. As the snow slowly accumulates and turns to ice, and the glacier increases in weight, the weight begins to deform the ice, forcing the glacier to flow downhill.
How much of a glacier is above the water line?
Over 90% of an iceberg's volume (and mass) is underwater. Therefore 10% is above the water.A glacier is a flow of ice downhill, driven by snow and ice accumulating in the mountains. When a part of the glacier breaks off and begins to float on the sea, it becomes an iceberg.
Where does a crevasses occur?
A crevasse is usually found near the terminal end of a glacier. As the ice mass moves down, it reaches a point where it begins to "split" and is more likely to produce a crevasse.

What is the bowl shaped depression where the valley glacier begins?
The Cirque is the name given to the bowl shaped depression were the valley glaciers usually begins. A glacier basically refers to a terminus that usually ends in a body of water.
What are the 2 types of glacier erosien?
Glaciers are ice sheets. There are 2 kinds of glaciers: alpine glaciers and continental glaciers. Alpine glaciers are formed when valleys above the snow line fill with ice and snow. Snow is compacted and gradually begins to flow downhill due to gravity. -Cham11

Where the river originates and how a river formed?
A river is originated up in the mountains. The river is created when snow or rain water goes downhill and begins to create a river. As the river goes downhill it cuts a v shaped valleys. When the river reaches a flatter slope it slows down and creates meanders. Then the river flows to its destination and deposits the sediment and rocks. Also known as deposition. Deposition can create oxbow lakes and deltas.
You are looking for a word where skiing begins with down?
'downhill'While it may seem obvious that all skiing would be downhill, nevertheless there is a sporting race in skiing that is specifically called 'downhill' skiing, or the 'downhill' event. This race has very few turns, as opposed to the skiing 'slalom' event, which is also downhill, but has a zigzag course with many turns.
What are the huge masses of snow and ice that move?
Once snow and ice reach more than 30 to 40 meters gravity begins to pull the glacier downhill.I hope I helped you!!! =)
