The average time taken for energy generated by thermonuclear fusion in the center of the Sun to reach the surface layers and escape is calculated to be
A) just a few seconds because this energy travels at the speed of light.
B) about 10 million years.
C) about 1 year.
D) 170,000 years.

Question

Quizplus · Accepted Answer

The process of energy generated by thermonuclear fusion traveling from the core of the Sun to the surface layers is a slow and gradual process. It takes around 170,000 years to reach the surface and escape into space due to the dense layers that make up the Sun's interior. Therefore, choice D is the correct answer.
