What kinds of elements make up the inner and outer core?

• Gases: hydrogen and oxygen

• Rocks: granite and shale

• Metals: iron and nickel

• Liquids: mercury and gold

Which layer of Earth is the densest?

• Mantle

• Crust

• Outer Core

• Inner Core

A variable that affects the state of matter of Earth's layers (thick layers of rock apply great forces to those layers buried below them, affecting the melting points of the buried rock.)

• Inner Core

• Outer Core

• Pressure

• Chemical composition

The third most dense layer and is made of liquid nickel and iron

• Lithosphere

• Physical properties

• Chemical composition

• Outer core

Crust

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

• A characteristic of the material in the asthenosphere, existing in a solid state yet having the ability to flow without being a liquid

• The thin solid outermost layer of Earth; is made of less dense silicates and is either continental (land) or oceanic (ocean floor)

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

Silicates

• Solid rock made of oxygen and silicon

• Solid rock made of oxygen and hydrogen

• Solid rock made of iron and nickel

• Liquid made of iron and nickel

The amount of matter in a given space or volume; a relationship between mass and volume.

• Pressure

• Density

• State of matter

• Plasticity

Inner Core

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

• The amount of matter in a given space or volume; a relationship between mass and volume

• The cool, rigid outermost layer of Earth, consisting of the crust and the uppermost part of the mantle, and broken into pieces or segments called plates

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

Lithosphere

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

• Characteristics that can be observed or measured, for example color, melting point, and conductivity

• The cool, rigid outermost layer of Earth, consisting of the crust and the uppermost part of the mantle, and broken into pieces or segments called plates

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