Sunspots.

Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.

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.
Sunspots sit on the sun's photosphere. The photosphere is the surface of the sun, and sunspots are dark regions on it that are visible. The photosphere's average temperature is about 5800 degrees Kelvin.
I believe that the layer in which sun spots occur would be the chromosphere. The chromosphere is the second layer in the sun's atmosphere and is about 2,000km above the photosphere(the first layer).
The black spots on the photosphere of the sun are called sunspots.

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.

Photosphere
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.

Yes. They are actually the result of charged particles streaming into and out of the photosphere (gaseous, "cool" outer layer) along magnetic field lines. The dark color is due to the cooler temperature at these spots. Sunspots are not, however, black.
