Outer layer of Earth. We live on the crust. It is the thinnest layer and made up of rock.

The largest layer located between the crust and the core. It is made of magma. Convection currents occur here.

Liquid layer of the Earth's core.

The solid, dense center of Earth. Made of iron and other minerals.

A large piece of the Earth’s crust that moves.

The theory that continents are carried along, or drift, because of plate movement.

Boundary between two colliding plates. The plates are moving towards each other.

Boundary where 2 plates separate. The plates are moving away from each other.

Boundary between sliding plates; the plates slide past each other. Often results in earthquakes.

An area where an oceanic plate sinks into the soft layer of the mantle. This occurs at convergent plate boundaries.

Very hot magma in the mantle that rises, then cools, then sinks again. This causes Earth's plates to move.

The study of Earth’s structure and history.

The supercontinent all continents were once part of millions of years ago.

Term	Definition
Crust	Outer layer of Earth. We live on the crust. It is the thinnest layer and made up of rock.
Mantle	The largest layer located between the crust and the core. It is made of magma. Convection currents occur here.
Outer Core	Liquid layer of the Earth's core.
Inner Core	The solid, dense center of Earth. Made of iron and other minerals.
Tectonic Plate	A large piece of the Earth’s crust that moves.
Continental Drift	The theory that continents are carried along, or drift, because of plate movement.
Convergent Boundary	Boundary between two colliding plates. The plates are moving towards each other.
Divergent Boundary	Boundary where 2 plates separate. The plates are moving away from each other.
Transform Boundary	Boundary between sliding plates; the plates slide past each other. Often results in earthquakes.
Subduction Zone	An area where an oceanic plate sinks into the soft layer of the mantle. This occurs at convergent plate boundaries.
Convection Currents	Very hot magma in the mantle that rises, then cools, then sinks again. This causes Earth's plates to move.
Geology	The study of Earth’s structure and history.
