A. Weathering

Weathering and erosion are often paired together, but they aren’t synonymous. In fact, weathering is the process that dissolves or wears away rock into smaller pieces. Erosion, however, is when rocks are picked up and moved to another place by ice, water, wind, or gravity.

The water cycle describes the processes of water moving on, above, or below the surface of the Earth. The continuous process includes six steps. The energy from the Sun drives the cycle by evaporating water from lakes, rivers, and even soil. The Sun is such an essential part of life for living things. You’re probably well aware of how important the Sun is, but there are plenty of other astronomy facts you didn’t learn in school.
