The amount of sun spots may vary over time, like in one year there would be 7 sun spots and then 20 the next year.

Visible dark spots on the sun are called?

We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.


What are the dark and cooler spots on sun called as?

Dark spots on the Sun are called sunspots. (You knew that was coming, didn't you?)


What are dark spots on the suns surface?

The dark spots on the Sun's surface are called Sunspots. These are formed by the sun's magnetic field because these areas have less convection underneath the sun's surface. Convection is how the sun's energy gets to the surface from the core in a circular motion. This reduces the heat in the area and makes the area appear darker than the surrounding sun. However, these spots are still extremely hot and can be many times the size of Earth!


What are dark spots that appear on the surface of the sun called?

Dark spots that appear on the surface of the sun are called sunspots. They are areas of reduced temperature caused by interactions with the sun's magnetic field.


What the black spots show up in the sun?

They are sun spots. Sun spots are cooler than the rest of the sun. They have strong magnetic field and usually occur in groups or in pairs. When they are in pairs one sun spot usually means the north pole of a magnet while the other means the south. Sun spots can sometimes be bigger than earth. The eleven year cycle of sunspots is the number of sunspots increasing and decreasing again. Hope that answered all your questions about sun spots.
