*7.10B PLATE TECTONICS

Front

What is the Pacific Plate?

Back

The Pacific Plate is the largest tectonic plate, located under the Pacific Ocean, and is known for its role in geological activities such as 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, causing geological phenomena like earthquakes, volcanoes, and mountain formation.

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 along faults.

Front

What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other horizontally, often causing earthquakes.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move towards each other, often resulting in one plate being forced below another, leading to subduction.

Front

What is a divergent boundary?

Back

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

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another plate, leading to volcanic activity and the formation of deep ocean trenches.

Front

What is the San Andreas Fault?

Back

The San Andreas Fault is a major transform fault in California that marks the boundary between the Pacific Plate and the North American Plate.

Front

What are ocean basins?

Back

Ocean basins are large depressions in the Earth's surface that are filled with ocean water, formed by tectonic plate movements, especially at divergent boundaries.

Front

What is the North American Plate?

Back

The North American Plate is a tectonic plate covering most of North America, parts of the Atlantic Ocean, and the Arctic Ocean.
