Earth's Processes and Sediment Dynamics

The video tutorial covers the natural processes of weathering, erosion, and deposition. It begins with an introduction to these concepts and proceeds to demonstrate how to create a plateau model using cornmeal. The tutorial then uses water to simulate weathering and erosion, showing how sediment is transported and deposited, forming new landforms.

What natural processes are responsible for the ever-changing nature of Earth's land?

• Glacial melting and freezing

• Volcanic eruptions and earthquakes

• Tectonic plate movements

• Weathering, erosion, and deposition

What material is used to create the plateau in the demonstration?

• Clay
