• outer core

• asthenosphere

• Inner core

• crust

The Earth is divided into different layers based on various physical properties. Which layer is a hot, thick layer where convection occurs?

• crust

• inner core

• outer core

• mantle

Which of the following statements describe the pressure from one layer to the next?

• Pressure increases as the weight of the layers above increases.

• Pressure increases with depth in the Earth, but it only applies to the mantle.

• Pressure between layers remains constant regardless of depth or material composition.

• Pressure decreases as you go deeper into the Earth, because the weight of the layers above becomes less significant.

Which layer heats the material in the mantle to form a convection current?

• crust

• core

• lithosphere

• mantle

The Earth is divided into different layers based on various physical properties. Which layer is a thin, rigid outermost layer that we live on?

• crust

• inner core

• outer core

• Mantle

Which of the following statements accurately describes a convection current?

• Heat is transferred through direct contact between the core and the crust.

• Less dense, hot magma rises to the surface and denser cooler magma sinks.

• More dense, hot magma rises to the surface and less dense cooler magma sinks.

• Convection currents can only occur in solids, as they require rigid structures to transfer heat.
