What is basal drag force?
Basal drag force is the resistance on a glacier's base as it moves over its bed. It occurs due to the friction between the glacier and the underlying rock or sediment. The amount of basal drag force can affect the speed and movement of the glacier.
Is it true that due to the force of friction a glacier will start to move downhill once the layer of snow and ice is more than about 30 to 40 meters deep?
Yes, the force of friction between the glacier and the ground is one of the factors that allows glaciers to move downhill under their own weight. This movement occurs once the thickness of the glacier reaches a critical depth where the force of gravity overcomes the frictional resistance. Once this threshold is reached, the glacier will start to flow downslope.
What is a destructive force that affects earth?
A destructive force that affects Earth is any natural disaster: tsunami, hurricane, tornado, etc. Also another destructive force is precipitation: rain, sleet, hail, etc.
When does gravity begin to pull a glacier downhill?
When the weight of snow and ice is great enough the glacier starts moving downhill under the influence of gravity. This point is determined by the relationship between accumulation and wastage of the glacier.
Is weathering a constructive or destructive force?
Weathering is generally considered a destructive force because it breaks down rocks and minerals into smaller particles through processes like physical weathering (e.g. frost action) or chemical weathering (e.g. oxidation). However, it can also contribute to soil formation and the creation of new landforms when combined with other processes like erosion and deposition.
What constructive and destructive about taku glacier Alaska?

Is a U-shaped valley constructive or destructive?
A U-shaped valley is considered a glacial landform resulting from the erosive action of a glacier. It is classified as a destructive force as the glacier carves and deepens the valley by plucking, abrasion, and glacial erosion.

What is constructive and destructive in taku glacier Alaska?
The Taku Glacier in Alaska is constructive because it helps to form new rivers and promotes the state's tourism industry. It can be destructive because if too big a piece calves it can destroy habitat and buildings.
