What is Plate Tectonics?

Back

The theory that explains the movement of the Earth's lithosphere, which is divided into tectonic plates.

How far do tectonic plates move each year?

Back

Centimeters per year.

Front

What are tectonic plates made of?

Back

Continental and oceanic lithosphere.

Front

What type of boundary occurs when two tectonic plates move apart?

Back

Divergent boundary.

Front

What is a convergent boundary?

Back

A boundary where two tectonic plates move toward each other.

Front

What is subduction?

Back

The process in which one tectonic plate sinks under another.

Front

What is a transform boundary?

Back

A boundary where two tectonic plates slide past each other.

Front

What geological feature is commonly found at divergent boundaries?

Back

Front

What is the lithosphere?

Back

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