Why is the sun spotty?

Answer 1

Sunspots are regions on the solar surface that appear dark because they are cooler than the surrounding photosphere, typically by about 1500 K (thus, they are still at a temperature of about 4500 K, but this is cool compared to the rest of the photosphere). They are only dark in a relative sense; a sunspot removed from the bright background of the Sun would glow quite brightly.

The sun has a magnetic field that is twisted around inside the Sun as it spins. There are places on the sun where this magnetic field rises up from below the sun's surface and pokes through, creating sunspots. Sunspots are magnetic and often have a north and south pole like a magnet. They come and go over the surface of the Sun and last from a few days to a few weeks. The period of time between maximum outbreaks of sunspots is about 9 to 14 years, with an average of 11 years.

Answer 2

The spots on the sun are known as sunspots and are areas of strong magnetic activity where the temperature is slightly cooler than the surrounding areas. They appear dark because they are cooler regions on the sun's surface, and their formation is linked to the sun's magnetic field.

Answer 3

because those spots are not spots they are craters and they form by astroids hitting the moon

Answer 4

Earth is tilted on it's axis .
