Exploring Weathering and Erosion: Key Differences and Processes

The video explains the processes of weathering and erosion, highlighting their differences. Weathering involves breaking down rocks, while erosion is the movement of these particles. The video covers three types of weathering: chemical, mechanical, and biological. It also discusses how erosion can be caused by water, wind, ice, gravity, and even human activities. The video concludes with a review of the key concepts and encourages viewers to consider the impact of these processes on the environment.

What is the difference between weathering and erosion?

• Weathering breaks rocks into smaller pieces, erosion moves them
