What causes Earth's tectonic plates to move?

Back

Convection currents in the mantle.

Front

What type of event occurs at a transform boundary?

Back

Earthquake.

Front

How do scientists estimate the thickness of each layer of the Earth?

Back

By studying seismic waves.

Front

What geologic feature is most likely to be found at a transform boundary?

Back

Earthquakes.

Front

What geologic feature is found at a divergent boundary between two pieces of oceanic crust?

Back

Mid-Ocean Ridge.

Front

Define plate tectonics.

Back

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

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with each other.

Front

What is a convergent boundary?

Back

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

Front

What is a divergent boundary?

Back

A tectonic boundary where two plates move apart, often creating new crust.

Front

What is a transform boundary?

Back

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