Front

Ocean ridges are formed by which type of plate boundary?

Back

Divergent.

Front

Why does oceanic crust subduct under continental crust?

Back

Because oceanic crust is dense.

Front

What causes convection currents in the Earth's mantle?

Back

Hot magma rises while cool magma sinks.

Front

What is a convergent plate boundary?

Back

A boundary where two tectonic plates move towards each other.

Front

What is a divergent plate boundary?

Back

A boundary where two tectonic plates move apart.

Front

What is a transform plate boundary?

Back

A boundary where two tectonic plates slide past each other.

Front

What geological feature is commonly formed at divergent boundaries?

Back

Mid-ocean ridges.

Front

What is subduction?

Back

The process where one tectonic plate moves under another plate.

Front

What is the lithosphere?

Back

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