Weathering Wonders of Earth and Its Role in Shaping Landscapes

The video explains weathering, the process of breaking down rocks and minerals, and its three types: chemical, mechanical, and biological. Chemical weathering involves chemical reactions, mechanical weathering involves physical forces, and biological weathering involves living organisms. Examples include the Grand Canyon and Carlsbad Caverns. The video concludes with a review of these concepts.
