7.2.5 Plate Tectonics

Front

What is a tectonic plate?

Back

A piece of the Earth's crust.

Front

What happens when two tectonic plates slam into each other?

Back

Continental mountains are formed.

Front

How does convection in the mantle affect tectonic plates?

Back

Hot liquid rock from the Earth's mantle rises, pushing the cold crust out of the way and forming new land.

Front

Where are earthquakes and volcanoes generally located?

Back

At the edges of plate boundaries.

Front

What type of plate boundary is formed when two plates collide?

Back

Convergent boundary.

Front

What is a divergent plate boundary?

Back

A boundary where two tectonic plates move away from each other.

Front

What is a transform plate boundary?

Back

A boundary where two tectonic plates slide past each other.

Front

What is the role of the Earth's mantle in plate tectonics?

Back

The mantle's convection currents drive the movement of tectonic plates.

Front

What geological features are formed at convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs.

Front

What geological features are formed at divergent boundaries?

Back

Mid-ocean ridges and rift valleys.
