Canyon or a Gorge
A U-shaped valley produced by the erosion of a valley glacier is called a glacial trough. This distinct feature is carved out by the movement of ice over time, shaping the landscape into a broad and deep valley with steep sides.
A valley carved by a stream in high mountains typically has a V-shaped profile, with steep sides and a narrow bottom. This shape is a result of the erosive power of the stream cutting down into the landscape over time, creating a deep, narrow channel.
A deep steep-sided valley formed by weathering and erosion is called a canyon. Canyons are typically formed by the gradual wearing away of rock by water and wind over long periods of time, creating a deep, narrow valley with steep sides.

A ravine is a narrow, deep valley with steep sides typically formed by water erosion. It is often characterized by its rugged terrain and lack of vegetation.
