峡谷指谷坡陡峻、深度大于宽度的谷地，是V形谷的一种。一般发育在构造运动抬升和谷坡由坚硬岩石组成的地段。当地面隆起速度与下切作用协调时，易形成峡谷。

A gorge refers to a valley with steep slopes and a depth greater than its width. It is a V-shaped valley, generally developed in a tectonic uplift section with a valley slope composed of hard rocks. It is easy to form a gorge when the uplift speed of the ground is in harmony with downcutting.
