What are the dark spots on the surface of the Sun that represent areas of cooler temperatures called?
Sunspots are dark areas on the sun's surface that are cooler than the surrounding area.
What are the cool magnetic fields that dot the surface of the sun?
Magnetic fields that dot the surface of the sun are known as sunspots. Although they are hardly cool in temperature, they are much colder than surrounding areas, which causes them to be visible as darkened spots.
Why are sunspots formed?
This would be due to star-cluterring. A grouping of any where from a dozen to a million stars that formed at he same time from the same cloud of interstellar gas. Stars in clusters are useful to aid our understanding of stellar evolution because, within a given cluster, stars are all roughly the same age and chemical composition and lie at roughly the same distance from Earth.
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 is the magnetic disturbance on the sun's surface called?
These magnetic disturbances are known as magnetic storms.
How will sun spots effect the earths weather?
Sunspots: One interesting aspect of the Sun is its sunspots. Sunspots are areas where the magnetic field is about 2,500 times stronger than Earth's, much higher than anywhere else on the Sun. Because of the strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases. This in turn lowers the temperature relative to its surroundings because the concentrated magnetic field inhibits the flow of hot, new gas from the Sun's interior to the surface. Sunspots tend to occur in pairs that have magnetic fields pointing in opposite directions. A typical spot consists of a dark region called the umbra, surrounded by a lighter region known as the penumbra. The sunspots appear relatively dark because the surrounding surface of the Sun (the photosphere) is about 10,000 degrees F., while the umbra is about 6,300 degrees F. Sunspots are quite large as an average size is about the same size as the Eart
Why does the number of sunspots vary?
The number of sunspots depends on the magnetic field of the Sun. This magnetic field changes with a period of roughly 22 years; twice in each of these magnetic cycles there is a maximum of sunspots. (So, the sunspot cycle has a period of about 11 years (on average), whilst the magnetic cycle has a period of about 22 years.)I am not sure whether the reasons for the magnetic cycles are completely understood, but you can check what is known so far, in the Wikipedia article on "Solar dynamo".

Why do solar flares happen near sunspots?
Sunspots are believed to be the sites where solar flares are generated. Sunspots are known to be "storms" on the sun's surface, but they are not yet fully understood.add The surface of our Sun is about 5800 deg C and above, and naturally most of the material is highly ionized. Thus large electrical currents may be generated, and these in turn cause the magnetic field loops seen as solar activity. These magnetic loops can accelerate the charged ions from the Sun, hence the name Solar Flare..
How does sunspots occurs?
They occur because of the sun has some spots on it that are slightly colder than the other areas of the sun. If we were to go to the sun, we would barely notice the sunspots. They are as big as a city and sometimes as big as earth itself. Sunspots produce solar flares which fling into space and then crash with the earth's magnetic field and go to the north and south. Most of the charged particles don't make it all of the way, though. The particles produce the aurora borealis also known as the northern lights.
How does the sun's magnetic field affect the solar system?
The sun's magnetic field is what causes the phenomenon known as sunspots. Magnetic fields also affect the earth's weather. Sunspots are a cyclical occurrence that cause solar flares, magnetic activity that affects the earth.
Are magnetic rocks known as lodestones?
Although Lodestone is a naturally occurring magnetic rock, not all magnetic rocks are known as lodestone, and it is only magnetized because of the magnetite mineral in it.
What causes solar flares prominences and sunspots?
Although the cause of flares is not completely understood, they are known to be associated with the magnetic field of the Sun. One favored explanation is that they occur when magnetic fields in the Sun pointing in opposite directions interact strongly with each other. Such a situation can be brought about by the churning motion of solar material near the surface, and is more likely during periods of the active sun. Thus, there typically is a correlation between the frequency of flares and the number of sunspots.
What is auroral?
Solar wind,ejected from the sunspots are high-energy particles which interact with the earth's magnetic field to form VAN ALLEN radiation belts.These particle eventually move towords the earth's magnetic poles where they collide with molecules in the atmosphere and radiates energy in the form of coloured lights known as auroral lights.
Why evaporation known as surface phenomena?
Evaporation is known as surface phenomena because molecules of water present on the surface of liquid are bonded weakly as compaered to inner molecules and when temperature increases hydrogen bonding between water molecules breaks.Due to this water molecules tend to evaporate.so that's why it is called as surface phenomena.
