Theory of Plate Tectonics Final

Front

What are tectonic plates?

Back

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

Front

How many tectonic plates are there approximately?

Back

There are about 20 tectonic plates.

Front

What is the theory of plate tectonics?

Back

A scientific theory that explains the movement of the Earth's plates and how they shape the Earth's surface.

Front

What is continental drift?

Back

The hypothesis that continents move across the Earth's surface over geological time.

Front

What is a transform boundary?

Back

A type of plate boundary where two plates slide past each other, causing earthquakes.

Front

Give an example of a transform boundary.

Back

The San Andreas Fault.

Front

What is a convergent boundary?

Back

A boundary where two tectonic plates collide, often forming mountains or causing subduction.

Front

What is a divergent boundary?

Back

A boundary where two tectonic plates move apart, leading to the formation of new crust.

Front

What can result from the movement of tectonic plates?

Back

Earthquakes and volcanic activity.

Front

What is subduction?

Back

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