Mancha solar

Sunspots are slightly cooler areas on the sun caused by magnetic activity. There is a strong correlation between the number of sunspots and the amount of energy the sun generates. More sunspots indicate higher solar energy output.

What are sunspots in relation to their surrounding areas on the sun?

• Darker areas

• Brighter areas

• Slightly cooler areas

• Hotter areas

What causes sunspots to form on the sun's surface?

• Nuclear reactions

• Gravitational pull

• Magnetic activity

• Solar flares

How does the number of sunspots relate to the sun's energy output?

• Fewer sunspots mean more energy

• The number of sunspots has no effect

• More sunspots mean more energy

• More sunspots mean less energy

Which of the following is true about the relationship between sunspots and solar energy?

• Sunspots only affect solar flares

• Sunspots increase solar energy

• Sunspots have no effect on solar energy

• Sunspots decrease solar energy

What is the correlation between sunspots and the sun's energy generation?

• Random correlation

• Direct correlation

• No correlation

• Inverse correlation
