Amplify- Plate Motion Post Assessment Review

Front

What is plate tectonics?

Back

Plate tectonics is the scientific theory that describes the large-scale movements of Earth's lithosphere, which is divided into tectonic plates.

Front

What happens at a convergent plate boundary?

Back

At a convergent plate boundary, two tectonic plates move toward each other, which can result in one plate being forced beneath another (subduction) or the plates colliding and creating mountains.

Front

Define subduction.

Back

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

Front

What is the lithosphere?

Back

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

Front

What is the asthenosphere?

Back

The asthenosphere is the semi-fluid layer of the upper mantle that lies beneath the lithosphere and allows tectonic plates to move.

Front

What are tectonic plates?

Back

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

Front

What is a transform boundary?

Back

A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally.

Front

What geological features can form at divergent boundaries?

Back

At divergent boundaries, new oceanic crust is formed, leading to features like mid-ocean ridges and rift valleys.

Front

What is an earthquake?

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.

Front

What is a fault?

Back

A fault is a fracture or zone of fractures between two blocks of rock, which can cause earthquakes.
