Why do nuclear fusion reactions only take place in the interior of a star
A)The magnetic fields are strongest there.
B)The temperature is the hottest in the center.
C)The density of material is very high in the center.
D)The temperature is the hottest in the center and the density of material is very high in the center.
E)FALSE; Nuclear fusion reactions can take place in the core and corona where temperatures are high enough.

Question

Quizplus · Accepted Answer

Nuclear fusion reactions require both high temperature and high density. The temperature is the hottest in the center of a star, and the density of material is also very high in the center due to the pressure from the layers above. As a result, the conditions in the center of a star are ideal for nuclear fusion reactions to take place. While temperatures may be high enough in the corona, the density of material is too low for fusion to occur in this region.
