Plate Tectonics

Front

What is a divergent boundary?

Back

A plate boundary where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

What drives the movement of tectonic plates?

Back

What is a convergent boundary?

Back

A plate boundary where two tectonic plates move towards each other, often leading to subduction or mountain building.

What is subduction?

Back

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

Front

What are transform boundaries?

Back

Plate boundaries where two plates slide past each other horizontally, often causing earthquakes.

Front

What is the lithosphere?

Back

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

Front

What role do tectonic plates play in earthquakes?

Back

Earthquakes occur primarily at plate boundaries due to the movement and interaction of tectonic plates.
