Question

Red giants are huge because their outer layers have expanded to a very low density tenuous atmosphere.

True
False

Answer 1

A red giant is not huge because its outer layers have expanded to a very low density tenuous atmosphere. Rather, a red giant is a large and bright star that has exhausted its core hydrogen fuel and is now burning helium in its core.

Step-by-step explanation:

False.

A red giant is not huge because its outer layers have expanded to a very low density tenuous atmosphere. Rather, a red giant is a large and bright star that has exhausted its core hydrogen fuel and is now burning helium in its core. As the core contracts and heats up, the outer layers of the star expand, causing the star to become larger in size.
