Rift Valley Due to tectonic activity, the Earth’s crust is expanded resulting in the making of Rift valleys. Golf was born in Scotland. There may be a river in the valley after the glacier has disappeared, but the upper walls of the valley or canyon will still show the tell-tale U-shape. V-shaped valleys, in contrast, are the result of rivers carving their course through the land. When temperatures drop and snow begins to fall, the water inside the valley trickles through the cracks in the rocks. U-shaped valley has been typically carved by a glacier.

The valleys are not found in all the hilly regions but are formed only in regions with higher altitudes. This geographical formation occurred primarily due to glacial erosion and also referred to as a trough valley or a glacial trough. The bottom of the valley is filled with a forest habitat. The size of the flowing glaciers is responsible for the size of the valleys thus formed. This KS3 Geography animation explains the ways in which glaciers shape the landscape. A valley is a low area between hills or mountains typically with a river running through it. Tributary valleys with such unequal or discordant junctions are called hanging valleys.
