Convection and Layers of Earth

List the order of Earth's Layers starting with the outermost layer.

• crust, lithosphere, mantle, outer core, inner core

• crust, mantle, lithosphere, inner core, outer core

• mantle, crust, outer core, lithosphere, inner core

• crust, outer core, mantle, lithosphere, inner core

Why is the Inner Core solid?

• Extreme Temperature

• Extreme Pressure

• Due to Convection Currents

• The Outer Core is Liquid

In which layer of the Earth are convection currents that result in the movement of the tectonic plates?

• Crust

• Lithosphere

• Asthenosphere

• Outer Core

How does material move in convection currents?

• Hot and cold material mixes together.

• Hot material rises and cold material sinks.

• Cold material rises and hot material sinks.

• Temperature has not affect on the movement of materials.

• Temperature Increases, Density Decreases, and Pressure Decreases.

• Temperature Decreases, Density Decreases, and Pressure Decreases.

• Temperature Increases, Density Increases, and Pressure Increases.
