Sunspots affect radio compunication and the weather.
The primary affect on the Earth is on our ionosphere

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

All surface artifacts of the sun are caused by magnetism (Magnesium is an element and does not affect much.) These phenomena include sunspots, solar flares, and plasma ejections.
Sunspots give off magnetic rays that affect terrestrial life. Then are just dark patches on the sun's surface that appear periodically. They are not as hot as other parts on the sun though.
You die!

These are called sunspots. These are the cooler darker areas on the sun.They range in size from 800 to 80000 km in diameter. They have very strong magnetic fields that can affect radio communications on earth. They follow an eleven year cycle called the sunspot cycle.
