List of land forms that are a result of the erosion work of rivers:
River erosion for prolonged periods alters the landmass. Some of the significant landmasses thus formed include valleys, waterfalls, potholes, river terraces, etc.
1. Valleys:
Valleys are formed when the river flow between two mountainous range causing fluvial erosion. Depending on the degree of erosion, the steepness of the valley varies. However, both the valley sides meet on the floor. Gorges and canyons are the two types of valleys usually formed.
2. Waterfalls:
Waterfalls occur due to sudden descent or break in the water flow. This may be due to steepness of the rocks, sudden earth movements, etc. The height of the waterfall depends on the difference in the topographic levels of the plains or the rocks thus moved.
3. Pot Holes:
Potholes are kettle-like small depressions formed in the rocky terrain and are cylindrical in shape.
4. Water Terraces:
Due to the sudden change or lowering of river floors, flat narrow surfaces on either side of the river bed are created called as river terraces.
