V型河谷（V-shaped valley）是地理学中一个重要的地貌现象，它通常出现在高山地区的河流流域中。本文将介绍V型河谷的形成原因、特征以及与其他河谷类型的比较。V型河谷的形成主要是由于河流的侵蚀作用。以下是形成V型河谷的主要过程：1.上游侵蚀：在高山地区，河流的流速较快，携带的固体颗粒会对河底和河岸进行磨蚀和冲刷。

V-shaped valleys are found in the upper part of a river, which is elongate depression of the Earth's surface. Valleys are commonly drained by rivers and slope denudation is typically characterized by the V-shape. Valley evolution is controlled mainly by climate and lithology. The angle of ...
U-shaped valleys aremonly found in areas where geological structures are relatively stable and have been subjected to long-term erosion, such as basins and lowlands. This type of valley has a relatively wide riverbed and gentle sides, resulting in a U-shaped landform. 2. Erosion intensity ...
