Exploring Weathering, Erosion, and Deposition Processes

The video tutorial introduces a hands-on science experiment to demonstrate weathering, erosion, and deposition. It begins with a list of materials needed, followed by setting up a river model using damp sand, water, and ice cubes to represent glaciers. The instructor explains how water causes weathering by breaking down rocks, erosion by carrying sediments, and deposition by dropping them off. A second demonstration shows how wind can also cause these processes. The tutorial provides a practical understanding of these geological processes.
