Question
Sunspots are produced by areas of strong magnetic fields that decrease the transport of energy to the surface by ________.
- Conduction
- Convection
- Induction
- None of these
Hint:
The literal meaning of the word is motion caused in a liquid by the tendency of hot, less dense matter to rise under the influence of gravity and colder, denser matter to sink, resulting in the transfer of heat.
The correct answer is: Convection
- A sunspot is a phenomenon on the photosphere of the sun that appears as a temporary spot that is darker than the surrounding area.
- Sunspots are produced by areas of strong magnetic fields that decrease the transport of energy to the surface by convection.
- So, the correct option is b.
