Earth's Interior

Front

What is the Earth's mantle?

Back

The Earth's mantle is a solid layer that flows, located between the crust and the outer core.

Front

What happens to magma when it cools down?

Back

When magma decreases in temperature, it becomes denser and sinks.

Front

What is the asthenosphere?

Back

The asthenosphere is a solid, putty-like layer made up of the upper mantle, located below the lithosphere.

Front

Which layer of the Earth is the hottest?

Back

The core is the hottest layer of the Earth.

Front

Is the outer core liquid or solid?

Back

The outer core is the only truly liquid layer inside the Earth.

Front

What is the lithosphere?

Back

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

Front

What is the difference between the inner core and outer core?

Back

The inner core is solid due to immense pressure, while the outer core is liquid.

Front

What is convection in the Earth's mantle?

Back

Convection is the process where hot magma rises, cools, and then sinks, creating a cycle that drives plate tectonics.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

What is the role of the mantle in plate tectonics?

Back

The mantle's convection currents help move tectonic plates on the Earth's surface.
