Weathering, Erosion, and Deposition Explained

The video tutorial covers the processes of weathering, erosion, and deposition. Weathering is the breakdown of rocks into smaller pieces through physical means like water, wind, and sun, as well as chemical reactions such as oxidation, hydrolysis, and carbonation. Erosion involves the movement of these smaller rock pieces by water, wind, and glaciers. Deposition is the process where sediments are laid down, forming new landforms like deltas and moraines. The video aims to educate viewers on these geological processes and their impact on Earth's surface.
