See how much you know about the weather.

Sorry! The correct answer is

B) Intense regions of magnetic activity.

Sunspots are areas of intense magnetic storms and are like freckles on the Sun’s surface. A close-up of one is shown in the picture at left. Sunspots are regions of reduced surface temperature which, compared to the surrounding areas of higher temperatures, makes them appear darker. A single "spot," however, can be 8 times the Earth’s diameter! Sunspots occur on an 11-year cycle, and scientists believe that sunspots influence weather patterns on Earth by affecting our magnetic field. In general, the heat energy from the sun is by far the most influential component of Earth's complex weather system, fueling evaporation, wind, temperature variations and many other phenomena.
