Please help me!!

A student drew this model to show the flow of convection currents
on Earth.
Part A
Is the model accurate? Explain your answer.

Yes the model is correct

Explanation:

Transfer of heat energy takes place usually any of these three processes namely; Conduction, Convection and Radiation. In conduction, transfer of heat energy takes place by microscopic collisions of particles within a body. In radiation, heat, light and energy through any source is sent out from something and moves through space without a material medium of propagation. In Convection, heat transfer happens because of the movement of the bulk of molecules within fluids.

We can define convection currents as a natural process of heat transfer involving the movement of energy and heat from one place to another.

The equator is the part on Earth that is nearest to the sun hence it receives much heat. As a result of this, the air near the equator rises upwards as it becomes less dense and later spreads out and again descends towards the equator. This process is responsible for the continual circulation of air which is called wind. It is due to the process of atmospheric convection currents that the clouds are kept aloft.

From the foregoing, the model shown in the image has been validated as a correct model of convection current in nature.
