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 is sea-floor spreading?

Back

The process by which new oceanic crust is formed at mid-ocean ridges as molten material rises from the mantle.

Front

What are the Earth's layers in order from the surface?

Back

Crust, Mantle, Outer Core, Inner Core.

Front

What type of boundary is formed when two tectonic plates slide past each other?

Back

Transform boundary.

Front

What is a convergent boundary?

Back

A tectonic boundary where two plates collide, often causing one plate to be forced beneath the other.

Front

What is a divergent boundary?

Back

A tectonic boundary where two plates move away from each other, leading to the formation of new crust.

Front

What is a transform boundary?

Back

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

Front

What is the San Andreas Fault?

Back

A major transform fault in California that is known for its seismic activity.

Front

What is the lithosphere?

Back

The rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the asthenosphere?

Back

The semi-fluid layer of the mantle beneath the lithosphere that allows tectonic plates to move.
