What is the solar cycle?
Hello. Thank you for reading this question. I am really stuck on this question for science class. What are solar cycles and could a part of the solar cycle affect earth? I hope you can answer this question. again, thank you for your time.
The term 'solar cycle' refers to a cycle of how active the Sun is and has a period of 11 years. It is thought that the luminosity, (or how bright the Sun is) may vary with this, and since all the energy on the Earth comes from the Sun, this could have a big effect on our climate. A nice website on all this is Sunspots and the Solar Cycle.
