Plate Boundaries Practice #1

Front

What does the tectonic drift theory explain?

Back

The tectonic drift theory explains that continents move.

Front

At which type of plate boundary is new crust formed?

Back

Divergent boundary.

Front

What type of boundary results in the spreading of the oceanic ridge?

Back

Divergent boundary.

Front

Where do convection currents in the mantle cause tectonic plates to diverge?

Back

Mid-ocean ridges.

Front

What is the MAIN result of two tectonic plates sliding past one another?

Back

Earthquakes.

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other.

Front

What is a convergent boundary?

Back

A plate boundary where two plates move towards each other, often causing one plate to be forced below the other.

Front

What is a transform boundary?

Back

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

Front

What is subduction?

Back

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

Front

What geological features are commonly formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys.
