Valleys are formed by numerous geographical processes. Glacial valleys, which are usually U- rather than V-shaped, were formed tens of thousands of years ago (most likely during the last Ice Age) by the massive erosive power of glaciers. Several glacial valleys can be found in the English Lake District and many can be found in Alpine countries. Rift valleys, such as the Great Rift Valley, are formed by the expansion of the Earth's crust due to tectonic activity beneath the Earth's surface. Valleys are, however, most commonly formed by fluvial activity (the action of running water, such as rivers), which erodes the landscape.

A valley is formed in couple ways. First by water. Uplift and erosion is the most common way. The ground pushes up, the water pushes down and moves out the eroded sediment. These valleys formed by rivers are in a V shape. Glacier activity also forms valleys. Carving our U shape valleys.

A valley could be created by a couple of ways. It could happen because of water erosion, by glacier activity (past or present) or because of earthquakes/volcanoes creating mountains around it.
