Question

How quickly do sunspots form? How long do they last? What is the length of the average sunspot cycle? (site 1)

Answer 1

The sunspots form when the sun's magnetic field protrudes through its surface. The sun's magnetic field is composed of tubes that affect the sun’s surface temperature at the point of protrusion. Hope this helps. Have a nice day.

Answer 2

Answer:

• There are different form or level of physical effects due to the sun rays or any electromagnetic radiations that are exposed to the human integumentary system or mainly the human skin.  As, they are formed to the degeneration of some of cells or the pigments present inside the human skin. As, they have the optimum level of requirements to grow and develop themselves, for that reasons the sunspots are created on the region or part of the human body to which the electromagnetic radiations are exposed.
• As, the sunspots may last for a much longer duration, which might precede in the formation of the sunspots which would last for a tenure of about seven years.
• While, the length of the average sunspot all depends upon the body mechanism of the target individuals.
