Front

What causes plate motion?

Back

Plate motion is primarily caused by the movement of tectonic plates due to convection currents in the mantle, not directly by earthquakes.

What is a cross section?

Back

A cross section is a diagram that shows what the inside of something looks like.

What is the significance of the fossil remains of Lystrosaurus found in India and South Africa?

Back

The fossil remains of Lystrosaurus found in India and South Africa suggest that these continents were once connected and have since drifted apart due to plate tectonics.

What is the mantle?

Back

The mantle is the layer of the Earth located between the crust and the outer core, composed of semi-solid rock that flows slowly.

What is the role of convection currents in plate tectonics?

Back

Convection currents in the mantle drive the movement of tectonic plates by causing them to rise and sink.
