Question

Explain what happens in the convection zone of the Sun and the visible results of this process. Please do not hand write a response. It is difficult to read.

Answer 1

The convection zone is the outer-most layer of sun. It is made of plasma. We can say that it is convecting that is boiling. It's temperature is about 2 million K compare to 5 million K of radiation zone. Radiation can't pass through convection zone. The radiation comes from the radiative zone cannot escape from the convection and a large amount of convection current sets up. As hot material from radiative zone reaches the top of the convection zone it begins to cool and sink and as soon as it is sinked temperature rises up again and producing a rolling motion just like bowl of hot water. When water boils you can see bubbles like shapes rolling down and come again.

We can only see the surface of the convection zone. If we point our telescopes towards the Sun, we can see that the surface is fully covered with convection cells. We can also see dark patches.

The convective motions themselves are visible at the surface as granules and supergranules.
