How can you describe the “heat flow” or convection currents in the Earth’s mantle?

• When magma is heated by the core, it becomes dense and sinks. When magma cools, it becomes dense and rises.

• The heat flow in the mantle bubbles up under the surface causing the surface to be warm.

• When magma is heated by the core, it becomes less dense and rises. When magma cools, it becomes dense and sinks.

• Heat flow comes up through volcanoes making the Earth warm enough to sustain life.
