Answer 2

Ans 1. Erosion is the process of removal of soil, rock or dissolved material from one place to another on the Earth's crust by natural actions such as water flow or wind.

Ans 2. An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but sometimes they get stuck at their edges due to friction.
