Answer:
The type of erosion that causes the 'most dramatic' and visible changes in the landscape is the gully erosion.
Step-by-step explanation:
- Gully erosion is the most rapid and noticeable type of erosion. It usually occurs in valleys and in rivers with steep walls.
- This type of erosion is stimulated by overflowing or flooding of the river. It increases with increasing speed and pressure of the water.
- Gully erosion is infamous in most 'parts of the world' for washing off land forms overnight.
