Describe one way the geosphere can change over time.
Plate tectonics – Movement of Earth’s plates can cause earthquakes, form mountains, and create valleys.
Explain in your own words:
Why is the mantle important to the structure of the Earth?
The mantle is important because it supports the crust, drives plate tectonics through convection currents, transfers heat from the core, and produces magma that forms new crust.
How does sedimentary rock form?
Sedimentary rock forms when sediments are compacted and cemented together over time.
