Earth's Layers

Rocky or rigid outer part of Earth consisting of the brittle crust and the top part of the upper mantle

• Lithosphere

• Oceanic Crust

• Continental Crust

• Asthenosphere

Mantle convection is the very slow creeping motion of Earth’s solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface.

• Lithosphere

• Earthquake

• Convection Currents

• Core

Solid, outer layer and is made of both the oceanic and continental crust.

• Hydrosphere

• Core

• Mantle

• Crust

NGSS.HS-ESS1-5

NGSS.HS-ESS2-1

Hot fluid or semi-fluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.

• Convection Current

• Lithosphere

• Core

• Magma

NGSS.HS-ESS2-3

The thick part of the earth's crust that forms the large landmasses. It is generally older and more complex than the oceanic crust.

• Oceanic Crust

• Continental Crust

• Magma

• Inner Core

NGSS.HS-ESS1-5

NGSS.HS-ESS2-1

The very center of the Earth, and the hottest part of the planet.

• Outer Core

• Inner Core

• Magma

• Lithosphere

A fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface.

• Inner Core

• Outer Core

• Lithosphere

• Asthenosphere

The mostly-solid bulk of Earth’s interior. It lies between Earth’s dense, super-heated core and its thin outer layer, the crust.

• Mantle

• Inner Core

• Outer Core

• Lithosphere

The outermost layer of Earth’s lithosphere that is found under the oceans.

• Continental Crust

• Mantle

• Inner Core

• Oceanic Crust

NGSS.MS-ESS2-3

The part of Earth's mantle lying beneath the lithosphere and believed to be much hotter and more fluid than the lithosphere.

• Asthenosphere

• Continental Crust

• Inner Core

• Outer Core
