What are the cooler areas on the sun called?
A
sun blasts
B
coronas
C
photospheres
D
sunspots
Explanation: 

Detailed explanation-1: -The cooler areas on the surface of the sun are called sunspots. They are seen as black spots on the surface of the sun and are relatively low-temperature regions in comparison with the brighter and hotter regions of the photosphere around them.

Detailed explanation-2: -Sunspots: One interesting aspect of the Sun is its sunspots. Sunspots are areas where the magnetic field is about 2, 500 times stronger than Earth’s, much higher than anywhere else on the Sun. Because of the strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases.

Detailed explanation-3: -There is no direct link between a single sunspot appearing and a short-term cooling in Earth’s temperature. “It will reduce the amount of light hitting the Earth by about 0.1%, ‘’ said Greg Kopp, a senior research scientist at the University of Colorado’s Laboratory for Atmospheric and Space Physics.

Detailed explanation-4: -Sun spots are the darker, cooler areas that are present on the surface of the Sun in a region called the photosphere. They are the regions where the magnetic field is about a thousand times greater than that of the Earth. The photosphere has a temperature of about Kelvins.
