Student Read

•Earth’s layers can be identified using two properties; (1) basic chemical composition, and (2) state of matter.

•As Earth cooled and formed a planet, the less dense elements of the crust and mantle separated, forming layers around the dense core.

•The crust and mantle are composed primarily of the elements, oxygen and silicon, known as silicates. Silicates of the mantle contain heavier elements, making them more dense than those found in the crust. The core is composed of the most dense materials, primarily iron and nickel.

Student Read

•The outer more is in the liquid state and the inner core is in the solid state of matter.

•The lithosphere is found in the solid state and is a layer that contains all of the crust and a little of the upper mantle.

•The asthenosphere is a shallow layer of the upper mantle and lies directly below the lithosphere.

•The state of matter of the asthenosphere is a solid; however, it has “plasticity” that allows it to flow.

Pass Out the Earth Layer Information Table

Layer of the Earth

• Lithosphere

• Composition

• Solid outermost layer of Earth’s surface.

Lithosphere

• Characteristics

• This layer contains the numerous living organisms that exist on Earth

Lithosphere

• Additional Facts:

• Contains the crust and tectonic plates.

Asthenosphere

• Composition

• Semi molten rock material

Asthenosphere

• Characteristics

• Solid with plastic characteristics that are similar to a liquid.

Asthenosphere

• Additional Facts:

• The plastic nature of this layer allows the tectonic plates to “float”.

Mantle

• Composition

• Contains molten rock material.

Mantle

• Characteristics:

• The thickest layer of Earth

Mantle

• Additional Facts

• The upper region of this layer is known as the asthenosphere.

Outer Core

• Composition

• Primarily composed of nickel and iron in a liquid form.

Outer Core

• Characteristics

• Superheated liquid layer

Outer Core

• Additional Facts

• This layer generates the magnetic field that protects living organisms from harmful solar particles.

Inner Core

• Composition:

• Primarily composed of nickel and iron in a solid form.

Inner Core

• Characteristics:

• Superheated solid material under extreme temperature and pressure.

Inner Core

• Additional Facts:

• This layer may have a temperature close to the temperature of the Sun’s surface.

Lithosphere * Composition

• Solid outermost layer of Earth’s surface
