Question

true/false: the corona layer is the least dense and coolest layer of the sun.
true
false
question 10
why does the sun produce its own light?
due to the chemical reactions happening in the outer layers
because gravitational compression releases light
it doesnt produce its own light, instead it reflects light from nearby stars
because nuclear fusion in the core releases enormous amounts of energy

Explanation:

The Sun produces light due to nuclear fusion in its core. Nuclear fusion combines hydrogen atoms into helium, releasing vast energy. Chemical reactions in outer layers don't generate light. Gravitational compression causes heat but not light emission. The Sun isn't a reflector like planets; it's a star creating its own light via fusion.

Answer:

Because nuclear fusion in the core releases enormous amounts of energy
