Geosphere

Front

What is the thickest layer of the Earth?

Back

The mantle is the thickest layer of the Earth.

Front

What type of crust is the thickest?

Back

The continental crust is the thickest type of crust.

Front

What is erosion?

Back

Erosion is the movement of soil and other surface materials from one place to another.

Front

What are large chunks of the Earth's crust called?

Back

Large chunks of the Earth's crust are called tectonic plates.

Front

On which layer can we find the tectonic plates?

Back

Tectonic plates are found on the lithosphere.

Front

What is the outermost layer of the Earth called?

Back

The outermost layer of the Earth is called the crust.

Front

What is the difference between continental and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.

Front

What is the role of the lithosphere in plate tectonics?

Back

The lithosphere is the rigid outer layer of the Earth that includes the crust and the upper mantle, where tectonic plates float and move.

Front

What causes tectonic plates to move?

Back

Tectonic plates move due to convection currents in the mantle beneath them.

Front

What is the significance of the asthenosphere in plate tectonics?

Back

The asthenosphere is a semi-fluid layer beneath the lithosphere that allows tectonic plates to move.
