Exploring Types of Weathering in Earth Science

The video tutorial explains weathering, a process that changes and breaks down rocks. It covers two main types: mechanical weathering, where rocks are physically broken into smaller pieces, and chemical weathering, where rocks undergo chemical changes. Mechanical weathering involves agents like ice, water, wind, gravity, and plants, while chemical weathering includes processes like oxidation and acid precipitation. The video also discusses the formation of caves and the role of lichens in weathering. The tutorial concludes with a review of how weathering transforms rocks into sediments.
