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
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.
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.
The increase in sunspot activities solar flares are a result. They are extra bursts of electrically charged particles and x-rays.
yes, some spots of it are very hot and others can be cooler (not really "cool", but less warmer)
No, sunspots are cooler than the photosphere.
What is true about sunspots
Sunspots are caused by magnetic activity on the surface of the sun. These are usually temporary and are viewed as dark compared to the areas surrounding the spot. These spots may emit solar flares that affect the solar system by sending out radiation from the Sun.
