Sun spots are the one found on the outer surface of the Sun.

Consider the statements regarding Sun spots.

1) Sun spots region generally have lower temperature than the surrounding region on

the Sun’s outer surface.

2) Sun spots do not have any effect on Earth’s climate.

3) Each period of weak Sun spot activity co-relates with the period of overall high solar

radiation output from the Sun’s surface.

Explanation:

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. Sunspots usually appear as pairs, with each spot
having the opposite magnetic polarity of the other.
Sunspot populations quickly rise and more slowly fall on an irregular cycle of 11 years,
although significant variations in the number of sunspots attending the 11-year period are
known over longer spans of time.
