Excerpt
The earth is in a constant state of motion, both as a planet in the solar system and as a body of interactive systems. Many of these systems create forces that change the face of the planet. The term weathering refers to any force that breaks down rocks and other objects in nature into smaller pieces. Erosion refers to the movement of the parts that were broken off through the weathering process.
