Sunspots are blindingly bright - they only appear dark due to the contrast of the surrounding matter, which is hotter and therefore brighter. Sunspots are typically around 1200 degrees Celsius (or Kelvin) cooler than the surroundings.
For more information about sunspots, I suggest reading the Wikipedia article on sunspots, or at least the introductory paragraphs.
Sunspots are cool regions of the suns surface that are also areas of intense magnetic fields.
The general theory behind sunspots is that the mangetic fields in the region have become all twisted and tangled as the gas in the sun moves around. This tangle interferes with the orderly motion of underyling convection cells. These convection cells are rising streams of hot gas that move energy in from the hot core of the sun (where the nuclear fusion generates energy) up to the surface. This just like how boiling water has hot spots that rise to the surface and cause it to roil and ripple.
By hampering these convection cells the magnetic fields essentially reduce the amount of heat and energy that spot on the sun recieves, allowing it to cool, and appear dark compared to it's surrounding area.
The surface of the sun is normally ~5,000o C, while a sunspot is ~3,500o C. That's still hot, but enough of a difference that it appears dark in comparison.
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They are caused by intense magnetic activity, which inhibits convection by an effect comparable to the eddy current brake, forming areas of reduced surface temperature
it is because of god
The twisting and tangling of magnetic field lines on the surface of the sun.
Caused by a concentration of magnetic activity on the surface of the sun. The magnetic activity causes the surface temperature to decrease, making the affected spot look darker than the surrounding area.
It isn't particularly hard; you can observe larger sunspots even in a small telescope. Warning: Don't try to look directly through the telescope at the Sun; this is very dangerous for your eyes. Instead, project the image on a piece of white paper placed behind the telescope.
Sunspots are places where it is cooler - about 1200 degrees Centigrade - than the surrounding matter. This, in turn, is caused by magnetic phenomena that reduce the convection at that point. The details of these magnetic phenomena are still being investigated.
Sunspots are made of exactly the same stuff as the rest of the surface of the Sun (hydrogen plasma). They appear because they are slightly cooler than the surrounding Sun Surface and are caused by loops of magnetic field pushing their way up through the surface of the Sun. These areas of intense magnetic field have the effect of inhibiting the convection of heat from the lower layers of the sun and this causes the area affected by the fields to be cooler than neighbouring areas. The temperature difference causes less light to be emitted by the Sun's photosphere in the area of the spot.
solar flares are caused by the periodic entangling and untangling of the sun's magnetic field. occasionally a field line becomes twisted to the point it tries to snap back into place, in doing so it can throw out a little solar material, a solar flare.
Sunspots appear to be darker because those areas are cooler than those around them.
Sunspots are caused by intense magnetic activity on the Sun.

The sun does not have an atmosphere. In the earth, the temperature in the different layers is not evenly distributed.
The sun has an extremely powerful gravitational field, and as a result, denser materials tend to fall to the lower layers.
the four main layers of the sun are: - corona - chromosphere - photosphere - sunspots (^_^) hope I answered it correctly..
Nine, if you include the minor layers, See related question.
3
That depends how you choose to count the layers. You can find details about the individual layers in the Wikipedia article about the Sun, among other places.
photosphere, chromosphere, and corona are the suns atmoshere made up of (=
to protect their skin from the sun and sand storms the layers are made from a cotton fabric that reflects the sun during the day so you stay cool and keeps you warm through the night

There are "layers" and there is a structure.
The sun does not have an atmosphere. In the earth, the temperature in the different layers is not evenly distributed.
The sun is made up several different layers, but the main 3 would have to be 1. Photosphere, 2. Chromosphere, 3. Corona.

because the sun is beuatiful
Your mom made the earths layers
