Detailed explanation-1: -Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. The temperature of a sunspot is still very hot though-around 6, 500 degrees Fahrenheit!
Detailed explanation-2: -As well as being a darker area on the sun, a sunspot is an area that temporarily has a concentrated magnetic field. This magnetic force inhibits the convective motion, which ordinarily brings hot matter up from the interior of the sun, so the area of the sunspot is cooler than the surrounding plasma and gas.
Detailed explanation-3: -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.
