A large number of sunspots indicates a high solar activity, which occurs on an 11-year cycle. Electronic communications can seriously be disrupted during this time.

How do sunspots change over time?

The number of sunspots increases then decreases in a fairly regular cycle, although it's not totally reliable. The time between each maximum or minimum is usually 11 years. I'm not sure if you mean how do individual spots change, but I've just given this answer about groups of sunspots.


What are the areas of cooler gases brought to the sun's surface through the convection zone?

As strange as it is to think of a body as hot as the sun having such a thing as a "cool" spot, it actually does! These areas are known as sunspots. Their number changes from year to year and they appear darker in color when studied by astronomers.


What can you conclude from your observations of sunspots?

Sunspots are temporary dark spots on the sun's surface caused by magnetic activity. Observations of sunspots help track the sun's 11-year solar cycle and provide insight into the sun's magnetic field and its effects on space weather. Changes in the number and size of sunspots can also affect Earth's climate and communication systems.


What is the most observable phenomena in the solar cycle?

The most observable phenomena in the solar cycle is the variation in the number of sunspots. Sunspots are dark areas on the Sun's surface that represent intense magnetic activity and are closely related to the overall activity level of the Sun. The number of sunspots follows an 11-year cycle, where the Sun goes from a solar minimum with fewer sunspots to a solar maximum with increased sunspot activity and then back to a minimum.

What are sunspots.how do they affect earth?

Sunspots are originally thought to be planets. They are darker than the surrounding photo sphere. Sunspots are caused by large magnetic fields


Are sunspots permanent features?

Sunspots are not permanent features on the Sun. They typically last for days to weeks, and then fade away. The number of sunspots varies in an 11-year cycle known as the solar cycle.

What part of the sun looks draker?

i think you mean darker. those are sunspots. sunspots are places on the sun that are much cooler than the rest of the sun. but that doesn't mean you could stand on one. it's still very hot.

Could the number of sunspots affect the amount of volcanic activity on earth?

Highly unlikely.
