plate tectonics and boundaries

Front

What is the core of the Earth primarily made of?

Back

Iron.

Front

What geological forces are responsible for mountain ranges?

Back

Converging tectonic plates.

Front

What happens at a subduction zone?

Back

The denser oceanic crust is subducting under the less dense oceanic crust.

Front

Where does sea floor spreading occur?

Back

At divergent plate boundaries (oceanic vs. oceanic).

Front

What is the upper rigid part of the Earth called?

Back

Lithosphere.

Front

What are tectonic plates?

Back

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

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move away from each other.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide.

Front

What is a transform boundary?

Back

A tectonic plate boundary where two plates slide past each other.

Front

What is subduction?

Back

The process where one tectonic plate moves under another and sinks into the mantle.
