8.9AB Plate Tectonics

Front

What is Plate Tectonics?

Back

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

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with one another, causing geological phenomena.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates push toward each other, often forming mountains or causing subduction.

Front

What is a transform boundary?

Back

A tectonic plate boundary where two 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 crust as magma rises.

Front

What is subduction?

Back

The process where one tectonic plate is forced under another, often leading to volcanic activity.

Front

What geological feature is commonly formed at convergent boundaries?

Back

Mountain ranges, such as the Himalayas, are commonly formed at convergent boundaries.

Front

What is the San Andreas Fault?

Back

A transform fault in California where the Pacific Plate and North American Plate slide past each other.

Front

What causes earthquakes?

Back

Earthquakes are caused by the sudden release of energy in the Earth's crust due to the movement of tectonic plates.

Front

Where is volcanic activity most likely to occur?

Back

Volcanic activity is most likely to occur at divergent boundaries and subduction zones.
