Which one of the following is an exogenic process, that is, one caused by forces acting on the Earth’s surface?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Erosion by running water
Forces working on the surface, such as running water, wind and glaciers, are exogenic; they wear down the land by erosion and build it up by deposition. Volcanic eruptions, folding and faulting are caused by endogenic forces from inside the Earth.
