Plate Tectonics

Front

What do tectonic plates consist of?

Back

Both continental and oceanic crust.

Front

What are the three types of plate boundaries?

Back

Convergent, divergent, transform.

Front

What is the inner core?

Back

Innermost layer of solid metal.

Front

What is the lower mantle?

Back

Solid material extending to Earth's core.

Front

What is the outer core?

Back

Layer of molten metal.

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 beneath the lithosphere that allows tectonic plates to move.

Front

What occurs at a convergent boundary?

Back

Tectonic plates move towards each other, often causing one plate to be forced below another.

Front

What occurs at a divergent boundary?

Back

Tectonic plates move apart from each other, leading to the formation of new crust.

Front

What occurs at a transform boundary?

Back

Tectonic plates slide past each other horizontally, causing earthquakes.
