Amplify Unit 2 Plate Motion - Review

Front

What is Earth's outer layer made of?

Back

Earth's outer layer is made up of hard, solid rock.

Front

What happens to tectonic plates at a Divergent boundary?

Back

At a Divergent boundary, tectonic plates move away from each other over time.

Front

What type of plate movement forms a mid-ocean ridge?

Back

A mid-ocean ridge forms from Divergent plate movement.

Front

How fast do tectonic plates typically move?

Back

Tectonic plates typically move at a rate of about 4 cm/year.

Front

What fills the gap created by plates moving apart?

Back

Soft, solid rock from underneath the plates rises and hardens, adding new solid rock.

Front

Define tectonic plates.

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing one plate to be forced below the other.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What geological features can form at divergent boundaries?

Back

Geological features such as mid-ocean ridges and rift valleys can form at divergent boundaries.

Front

What is the lithosphere?

Back

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