Weathering and Erosion: Mechanical Weathering

The video explains mechanical weathering, where rocks are physically altered but not chemically changed. It covers processes like abrasion, temperature fluctuations, and the effects of freezing and thawing. Examples include rock flaking in Yosemite and Hoodoo formation in Bryce Canyon. Biological weathering by plant roots is also discussed.

What role do temperature fluctuations play in the weathering of rocks?

Explain how freezing and thawing can lead to the breaking of rocks.
