Layers of the Earth

Small particles of broken down rock can be formed into sedimentary rock when they are buried and then –

• melted completely because of extreme heat.

• compressed and cemented together.

• pushed upward and exposed to wind and water.

• contaminated by underground nuclear material.

In order for plants to be changed into fossil fuels, they must first die and then be –

• eaten by consumers.

• completely dried out.

• buried deep underground.

• evaporated.

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

• Exosphere

• Asthenosphere

• Mesosphere

• Thermosphere

The thin, solid, outermost layer of Earth; is either continental (landmasses) or oceanic (ocean floors)

• Earth's mantle

• Earth's core

• Earth's lithosphere

• Earth's 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

• Plateosphere

• Lithosphere

• Crustosphere

• Mantlecore

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

• mantle

• lithosphere

• crust

• core

The outer layer of Earth’s core; surrounds the inner core and is made of liquid nickel and iron

• Inner core

• Mantle

• Crust

• Outer core

The sphere of solid nickel and iron at the center of Earth; surrounded by the liquid outer core

• Middle core

• Inner core

• Outer core

• Central core

A characteristic of the material in the asthenosphere; existing in a solid state yet having the ability to flow

• Plasticity

• Liquid

• Solid

• Gas
