Question

Quizplus · Accepted Answer

Convection is the energy-transporting process in a star's interior that also plays a role in moving heavy elements from their production region to the star's surface and from there into outer space. As convection currents carry hot gas from deeper in the star to the surface, they also transport heavier elements that were created in the star's core. Once at the surface, these elements can be expelled into space through stellar winds or as the result of a supernova explosion.
