Amplify- Plate Motion Post Assessment Review

Front

What is plate tectonics?

Back

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

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other, causing geological activity such as earthquakes and volcanic eruptions.

Front

What is continental drift?

Back

The gradual movement of continents across the Earth's surface through geological time.

Front

What is subduction?

Back

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

Front

What is a fault line?

Back

A fracture or zone of fractures between two blocks of rock, which can lead to earthquakes.

Front

What is an earthquake?

Back

A sudden shaking of the ground caused by the movement of tectonic plates.

Front

What is a volcano?

Back

An opening in the Earth's crust through which molten lava, ash, and gases are ejected.

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, allowing tectonic plates to move.

Front

What evidence supports the theory of plate tectonics?

Back

Fossil distribution, similar rock formations across continents, and the fit of continental coastlines.
