Characteristics [edit]. Bantams are suitable for smaller backyards as they do not need as much space as other breeds. Bantam hens are also used as laying hens, with some breeds laying up to 150 eggs per year. However, Bantam eggs are only about one-half to one-third the size of a regular hen egg.antams are suitable for smaller backyards as they do not need as much space as other breeds.

All in all, the sunspots appear dark because the are darker than the surrounding surface. They're darker because they are cooler, and they're cooler because of the intense magnetic fields in them. share | improve this answer.
Sunspots always appear in pairs and are intense magnetic fields (about 5,000 times greater than the Earth's magnetic field) that break through the surface. Field lines leave through one sunspot and re-enter through the other one. The magnetic field is caused by movements of gases in the sun's interior.Sunspot activity occurs as part of an 11-year cycle called the solar cycle where there are periods of maximum and minimum activity.t is not known what causes this 11-year cycle, but two hypotheses have been proposed: 1  Uneven rotation of the sun distorts and twists magnetic field lines in the interior. 2  The twisted field lines break through the surface forming sunspot pairs. 3  Eventually, the field lines break apart and sunspot activity decreases.
