TEK 6.10A Layers of the Earth

The sphere of solid Nickel and Iron at the center of Earth; Surrounded by the liquid outer core.

• Inner Core

• Outer Core

• Mantle

• Crust

The outer layer of Earth's Core; surrounds the Inner core and is made of liquid nickel and iron.

• Inner Core

• Outer Core

• Mantle

• Crust

The solid layer of Earth between the crust and the core; made of dense silicates.

• Inner Core

• Outer Core

• Mantle

• Crust

The thin, solid outermost layer of Earth; made of less dense silicates and is either continental (landmasses) or oceanic (ocean floors).

• Inner Core

• Outer Core

• Mantle

• Crust

The cool, rigid, outermost layer of Earth that consists of the crust and the uppermost part of the mantle; broken into pieces or segments called plates.

• Lithospehere

• Asthenosphere

• Mesosphere

• Atmosphere

NGSS.MS-ESS2-3

The solid layer with plasticity in the upper mantle that is located just below the lithosphere; lithospheric plates "float" and move on this layer.

• Lithosphere

• Asthenosphere

• Atmosphere

• Mesosphere

NGSS.MS-PS1-1

The more dense part of Earth's crust that underlies the oceans.

• Oceanic Crust

• Continental Crust

• Mechanical Layers

• Compositional Layers

The less dense part of the Earth's crust that forms large land masses.

• Oceanic Crust

• Continental Crust

• Mechanical Layers

• Compositional Layers

Layers differ in physical properties (state of matter and how the layers transfer heat); Lithosphere, Asthenosphere, Mesosphere, Outer Core, Inner Core
