What keeps the Sun's outer layers from continuing to fall inward in a gravitational collapse?
A)outward pressure due to super- heated gas
B)electromagnetic repulsion between protons
C)the strong force between protons
D)neutrinos produced by nuclear fusion drag gas outward

Question

Quizplus · Accepted Answer

The outer layers of the Sun are held up by the outward pressure of superheated gas, which is generated by the heat and light produced by nuclear fusion reactions in the core. This outward pressure balances the inward pull of gravity, resulting in a stable star.
