Physical Geography Flashcards

Continental Crust

The thicker and less dense outer layer of Earth's crust where landmasses exist.

Oceanic Crust

The thinner and denser outer layer of Earth's crust located beneath oceans.

Mantle

A very thick layer beneath the crust made of hot, semi-solid rock whose movement helps drive plate movement.

Outer Core

Layer of Earth mainly made of liquid iron and nickel whose movement produces much of Earth's magnetic field.

Inner Core

Layer of Earth made of solid iron and nickel that remains solid under enormous pressure despite being extremely hot.

Atmosphere

The layer of gases surrounding Earth.

Hydrosphere

All the water on Earth, including oceans, rivers, lakes, groundwater, glaciers, and water vapour.

Lithosphere

The solid outer part of Earth, including the crust and uppermost mantle.

Biosphere

All parts of Earth where living things exist.
