Question

At which location does heat transfer begin as dense material heats up?

1
2
3
4

Answer 1

Explanation:

At the surface, the warm soup spreads out and cools, becoming denser. Gravity pulls this cooler, denser soup down to the bottom, where it is heated again and begins to rise. This flow that transfers heat within a fluid is called a convection current.

Answer 2

Answer:

Heating and cooling of the fluid, changes in the fluid density, and the force of gravity, combine to set convection currents in motion. Heat from the core and the mantle itself cause convection currents in the mantle. Convection currents take place in the core and the
