Plate Tectonics

Front

What is Plate Tectonics?

Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What are the two types of crust?

Back

Continental crust and oceanic crust.

Front

What is subduction?

Back

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

Front

What is a convergent boundary?

Back

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

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other, often creating new oceanic crust.

Front

What is Pangea?

Back

A supercontinent that existed around 200 million years ago, where all continents were joined together.

Front

What geological feature is formed at a convergent boundary?

Back

Mountains are often formed at convergent boundaries due to the collision of tectonic plates.

Front

What is the San Andreas Fault?

Back

A transform fault in California known for its significant earthquake activity.

Front

What is oceanic crust?

Back

The part of the Earth's crust that underlies the ocean, typically thinner and denser than continental crust.
