Plate Boundaries

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to one plate being forced below the other, often resulting in earthquakes and volcanic activity.

Front

Which plate typically subducts in a convergent zone?

Back

The plate which is more dense in the collision zone.

Front

What happens to oceanic crust at a convergent oceanic boundary?

Back

Oceanic crust is destroyed.

Front

Which ocean is currently getting larger?

Back

The Atlantic Ocean.

Front

What type of crust will subduct if two plates converge?

Back

Oceanic crust.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move apart from each other, leading to the formation of new crust as magma rises to the surface.

Front

What is created at a divergent boundary?

Back

New oceanic crust (sea floor) is created.

Front

What is a transform boundary?

Back

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

Front

What is 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.
