What causes tectonic plate movement?

Back

Convection currents in the mantle.

Front

What is the surface of the Earth called, and what does it sit atop?

Back

The surface is called the lithosphere, and it sits atop a liquid layer called the asthenosphere.

Front

Define lithosphere.

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the mantle beneath the lithosphere.

Front

What is the significance of the outer core?

Back

The outer core is responsible for generating Earth's magnetic field through the movement of molten iron.

Front

Explain the concept of convection currents in the mantle.

Back

Convection currents are the circular movements of molten rock in the mantle caused by heat from the Earth's core.
