A V-shaped valley is a distinctive landform created by rivers in their youth (upper course). It is a key topic in Class 9 and 10 Geography (Drainage chapter).
Formed by: River vertical erosion.
Location: Upper course of a river (in mountains).
Shape: Narrow, steep-sided, V-profile.
Example: Many Himalayan gorges (like Indus Gorge).
In the upper course of a river (mountains/hills), the river flows fast with high energy and cuts sharply downward into the bedrock through a process called vertical erosion (downcutting).
As the river cuts deep into the ground, the valley walls are left steep and high. Gravity and weathering cause the sides to crumble slightly, giving the valley a characteristic V shape when viewed in cross-section.
Conditions: V-shaped valleys form where:
| Feature | V-Shaped Valley | U-Shaped Valley |
|---|---|---|
| Formed by | River (water) | Glacier (ice) |
| Course | Upper/mountain course | Glaciated mountain regions |
| Shape | Narrow, pointed bottom | Wide, flat bottom |
| Example | Himalayan gorges | Kashmir Valley |
A V-shaped valley is formed by the rapid vertical erosion (downcutting) of a fast-flowing river in its upper mountainous course. The river cuts deeply downward, leaving steep sides that form a V-shape.
