Plate Boundaries

Front

What is a divergent plate boundary?

Back

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

Front

What occurs at a divergent boundary between two oceanic plates?

Back

Sea floor spreading occurs at a divergent boundary between two oceanic plates.

Front

What is formed along a divergent boundary?

Back

New crust is formed along a divergent 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 is a tectonic plate?

Back

A tectonic plate is a large slab of the Earth's lithosphere that moves over the asthenosphere.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often leading to one plate being forced beneath another.

Front

What is a transform plate boundary?

Back

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

Front

What is subduction?

Back

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

Front

What geological features can form at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs can form at convergent boundaries.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is created at divergent boundaries as magma rises to the surface.
