The asthenosphere which contains the crust and mantle.
The lithosphere which contains the crust and outer core.
The lithosphere which contains the crust and upper mantle.
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.
