The three compositional layers of the Earth are

• inner core, outer core, crust

• Core, mantle, crust

• mantle, crust, lithosphere

• crust, lithosphere, atmosphere

Compositional layers refer to the

• the order of the layers

• the depth of each layer

• Material each layer is made from

• how the layers interact

The outer most layer of the Earth is also known as the

• lithosphere

• land

• mantle

• asthenosphere

The outer core is

• made of gas

• solid metal

• liquid metal

Temperatures at the inner core are above the melting point of the metals it is composed of. The inner core is

• liquid because the metals have melted

• solid because the metals have cooled over time

• solid because it is under extremely high pressure

• liquid because the metal is mercury
