Outer Core
Earth's molten (liquid) layer made of iron and nickel.
Inner Core
Earth's layer that is a dense solid ball of metal.
Atmosphere
A thin layer of gases that forms around Earth's outer most layer.
Earth's magnetic field
Scientist believe that this is created by the movement of the liquid metal outer core.
Igneous
Rock formed from the cooling of magma and lava.
Metamorphic
Rock formed from heat and pressure inside Earth's crust changing the materials of a rock.
Sedimentary
Rock formed when pieces of sediment deposit in layers.
Lava
Molten rock that reaches Earth's surface.
Magma
Molten rock BELOW Earth's surface.
Sediment
Created by the weathering and erosion of rock.
Biosphere
Contains Earth's living organisms.
Hydrosphere
Contains all of Earth's water.
Geosphere
Made of three main parts: metal core, solid middle and rocky outer layer.
