Plate Tectonics

Front

What type of force occurs at a convergent boundary?

Back

Compression

Front

What is the primary composition of continental crust?

Back

Light granite rock

Front

What is the mechanism that causes convection currents in the mantle?

Back

Hot magma rises while cool magma sinks.

Front

What type of plate boundary is associated with the formation of faults?

Back

Transform boundary.

Front

What is the name of the upper part of the mantle that is semisolid and allows for convection?

Back

Asthenosphere.

Front

What are the three main types of plate boundaries?

Back

Convergent, Divergent, and Transform.

Front

What geological feature is commonly formed at convergent boundaries?

Back

Mountains or deep ocean trenches.

Front

What is the process called when tectonic plates move apart?

Back

Divergence.

Front

What is the significance of the lithosphere in plate tectonics?

Back

It is the rigid outer layer of the Earth that includes the crust and upper mantle.

Front

How do tectonic plates interact at divergent boundaries?

Back

They move away from each other, creating new crust.
