Exploring Weathering, Erosion, and Deposition

Mr. Hammett explains the geological processes of weathering, erosion, and deposition, focusing on how water influences these processes. He uses relatable examples, such as cookies and streams, to illustrate how rocks break down, move, and settle over time. The video emphasizes the role of water in shaping landscapes through these processes, providing visual evidence and a recap to reinforce learning.

• By heating rocks

• By moving rocks and causing them to smash into each other

• By freezing and expanding

• By dissolving rocks

What is erosion?

• The chemical alteration of rocks

• The breakdown of rocks into smaller pieces

• The formation of new rocks

• The movement of broken-down rocks from one place to another
