How does convection occur in stellar bodies?

1 Answer

Convection in stellar bodies like stars happens when hotter gases from the core move outwards and release (transfer) their energy whilst the cooler gases move back into the hotter core area.

Explanation:

The above explained phenomenon accounts directly to the heat radiation by stars.

Hot wind currents tend to go upwards as they weigh less (less density), while cool currents go downwards due to the lesser particles movement.
