In which direction did South America drift away from Pangaea?

Back

West.

Where is Earth's heat energy most concentrated?

Back

The core.

Front

What are convection currents?

Back

The movement of fluid caused by differences in temperature and density, which helps drive plate tectonics.

Front

What is the mantle?

Back

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

Front

What is the lithosphere?

Back

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

Front

What is the core?

Back

The innermost layer of Earth, composed mainly of iron and nickel, and is divided into a solid inner core and a liquid outer core.

Front

What is the relationship between tectonic plates and earthquakes?

Back

Earthquakes occur when tectonic plates move and interact at their boundaries, causing stress to be released.
