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.
The method was later improved by Babcock and others, allowing astronomers to observe not only the magnetic field of sunspots but also the weak fields near the Sun's poles. It turned out that the Sun has a polar field somewhat like the Earth's, but that it reverses its polarity during each 11-year cycle. Sunspots have also led us to a better understanding of the Earth's own magnetic field. The face of the Sun consists of ionized hot gas (plasma), hot enough to conduct electricity.
