A typical spot consists of a dark region called the umbra, surrounded by a lighter region known as the penumbra. The sunspots appear relatively dark because the surrounding surface of the Sun (the photosphere) is about 10,000 degrees F., while the umbra is about 6,300 degrees F. Sunspots are quite large as an average size is about the same size as the Earth.

∙ 9y agoA black spot on the sun is known as a sunspot and is a phenomenon that is temporary in nature. It occurs on the suns photosphere and is caused by magnetic activity so intense that it inhibits convection in that particular area.

∙ 13y agoSun spots form in pairs when a loop of solar magnetic flux breaks through the photosphere. The flux lines push away the plasma of the photosphere, exposing the slightly cooler layer of the sun just below the photosphere making the spots look dark.
If the spots stay long enough, the flux loop connecting them will pick up plasma becoming a solar prominence. If there is enough energy in the flux lines they might "break" and eject the plasma they have picked up as a solar flare.

What are dark spots that appear on the surface of the sun called?
Sunspots
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?)
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.
Why do sunspot appear in dark?
Because they are cooler than the rest of sun's surface.Even though the spots are cooler,They are still 6000 degrees.The other surface of sun is 10000 degrees.
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?
Sunspots
What is an explanation of why sunspots appear dark?
The sun spots are the cooler spots. They are darker because there isnt much heat compared to the rest of the sun
Why do sunspots appear darker?
Because the sunspots are cooler spots on the sun. They are much different from the rest of the sun so the appear really dark.

What is a violent storm on the sun that has huge clouds of large bright loops or arches gases?
They''re called sun-spots. They appear as dark 'spots' on the surface of the Sun. The bright 'arches' are solar flares resulting from the storm's energy.
Why do spots appear dark?
Spots appear dark because they are much cooler than the surrounding area. They are still very hot, but not as much as the rest of the Photosphere.
What are dark areas on the sun surface called?
