The answer of how it is convert is the sun generates energy
by slowly contracting in size; converting gravitational potential energy into
thermal energy and this is called gravitational contraction. Gravitational collapse is the narrowing of an
astronomical object due to the effect of its own gravity, which tends to draw
matter inward toward the center of gravity.
I think the correct answer is crust. I am really sorry if I am wrong.
