Which of the following options is correct regarding sunspots?
Explanation
Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas.
  • They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection. Sunspots usually appear in pairs of opposite magnetic polarity
  • Individual sunspots or groups of sunspots may last anywhere from a few days to a few months, but eventually, decay. Sunspots expand and contract as they move across the surface of the Sun, with diameters ranging from 16 km (10 mi)to 160,000 km (100,000 mi).
  • Larger sunspots can be visible from Earth without the aid of a telescope.
    Hence, the correct option is (b).
    • a)
      The opposite surface of moon where no light reaches
    • b)
      Area on Sun's photosphere that appears as dark spots due to reduced surface temperature
    • c)
      Polar region of Sun
    • d)
      Black spot on moon
    Correct answer is option 'B'. Can you explain this answer?

    Sunspots

    Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas.

    Causes of Sunspots

    - They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection.
    - Sunspots usually appear in pairs of opposite magnetic polarity.

    Duration and Size of Sunspots

    - Individual sunspots or groups of sunspots may last anywhere from a few days to a few months, but eventually, decay.
    - Sunspots expand and contract as they move across the surface of the Sun, with diameters ranging from 16 km (10 mi) to 160,000 km (100,000 mi).
    - Larger sunspots can be visible from Earth without the aid of a telescope.

    Conclusion

    Hence, option 'B', which states that sunspots are areas on the Sun's photosphere that appear as dark spots due to reduced surface temperature, is the correct option.
