How are hanging valleys formed?
A hanging valley can be formed when the lower valley has a greater rate of erosion. This can be cause by 2 glacier flows, one feeding the other. This may also be caused by a greater flow of water in the lower valley or soft rock layers that erode more quickly.
How are flat floored valleys formed?
Flat-Floored Valley These valleys, like V-shaped valleys, are formed by streams, but they are no longer in their youthful stage and are instead considered mature. With these streams, as the slope of a stream’s channel becomes smooth, and begins to exit the steep V or U-shaped valley, the valley floor gets wider.

Are mountains and valleys useful?
Valleys of this type often have a very large river with many “tributaries” (streams that are like branches) running through them. The tributaries carry water from the hills or mountains that may be far from the main river. Valleys of this type are very useful for growing food crops.
Why are valleys good for farming?
Farmers depend on what little water the rainy season can provide. Only in the rainy season can farmers plant corn. In some higher elevation small valleys, water is a little more abundant and farmers can manage planting peanuts, and vegetables such as eggplants, squash, and tomatoes along with the corn.
Is Valley a source of water?
Most commonly, they arise from erosion over long periods of time by moving water and are known as river valleys. Typically small valleys containing streams feed into larger valleys which in turn feed into larger valleys again, eventually reaching the ocean or perhaps an internal drainage basin.
