Plate Tectonics

Front

What is the theory of plate tectonics?

Back

The theory of plate tectonics explains how the Earth's outer shell, or lithosphere, is divided into several plates that glide over the semi-fluid asthenosphere beneath. This movement causes geological events like earthquakes and volcanic eruptions.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other. They can be continental or oceanic.

What is the name of the plate located in Africa?

Back

African Plate.

Front

What is the name of the plate located in North America?

Back

North American Plate.

Front

What is the name of the plate located in Eurasia?

Back

Eurasian Plate.

Front

Where do most earthquakes occur according to the theory of plate tectonics?

Back

Most earthquakes occur along plate boundaries.

Front

What geological event is most likely to occur along the San Andreas fault system?

Back

Earthquake.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often causing one plate to be forced below another, leading to earthquakes and volcanic activity.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move apart from each other, often creating new crust as magma rises to the surface.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, which can cause earthquakes.
