Valleys are typically carved by a combination of erosion processes such as rivers, glaciers, or tectonic activity. Rivers erode valleys through the flow of water, gradually wearing away the land over time. Glaciers can carve U-shaped valleys by plowing through the landscape, while tectonic activity, like faulting or folding, can create valleys through the movement of the Earth's crust.

Are U-shaped valleys destructive or constructive?
U-shaped valleys are considered destructive landforms because they are formed by the erosive action of glaciers. As glaciers move downhill, they carve and widen valleys, creating a U-shaped cross-section with steep sides. This erosional process transforms V-shaped valleys into U-shaped valleys over time.
Are v- shaped valleys destructive and constructive?
V-shaped valleys are typically associated with erosional processes, such as the downcutting of rivers. They are considered destructive because they result in the removal of rock and soil from the landscape. However, v-shaped valleys can also be considered constructive in the sense that they contribute to the formation of new landforms and landscapes over time.

How does a stream widen its valley?
Valleys deepening and widening are caused by several factors. V-shaped valleys are caused by forces such as erosion and rivers. Valleys are not at all formed by rivers. Valleys that are not V-shaped were formerly occupied by glaciers and are characteristically U-shaped, formed by the huge bodies of ice that moved along; they carved the valleys as they passed, carrying away giant boulders and huge amounts of debris.
