Types of plate boundaries

Front

What is a subduction zone?

Back

A subduction zone is formed when a more dense tectonic plate sinks below a less dense plate.

Front

What type of plate boundary occurs when two plates collide?

Back

Convergent boundary.

Front

What happens at a divergent boundary?

Back

Plates diverge or move apart from each other.

Front

What is subduction?

Back

Subduction occurs when a less dense plate slides under a more dense plate.

Front

What type of plate boundary is characterized by sliding past each other?

Back

Transform boundary.

Front

What is the lithosphere?

Back

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

Front

What geological features are commonly formed at convergent boundaries?

Back

Folded mountains, deep ocean trenches, and volcanic arcs.

Front

What geological features are associated with divergent boundaries?

Back

Mid-ocean ridges and rift valleys.

Front

What is the main driving force behind plate tectonics?

Back

Convection currents in the Earth's mantle.

Front

What is a transform fault?

Back

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