Amplify- Plate Motion Post Assessment Review

Front

What is plate tectonics?

Back

The theory that explains the movement of Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What are tectonic plates?

Back

Large, rigid pieces of Earth's lithosphere that move and interact at their boundaries.

Front

What happens at convergent plate boundaries?

Back

Two plates move toward each other, which can cause one plate to be forced beneath the other, leading to subduction.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.

Front

What occurs at divergent plate boundaries?

Back

Two plates move away from each other, allowing magma to rise and create new crust.

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The semi-fluid layer of the mantle beneath the lithosphere that allows tectonic plates to move.

Front

What is a fault?

Back

A fracture in the Earth's crust where blocks of rock have moved past each other.

Front

What is an earthquake?

Back

A sudden release of energy in the Earth's crust that creates seismic waves.

Front

What is a volcano?

Back

An opening in the Earth's surface through which molten rock, ash, and gases can escape.
