What are sunspots really?
Sunspots are parts of the Sun that are about 1200 degrees centigrade cooler than the surroundings.
What are halo gases around the sun called?
The Corona.
How are sunspots related to prominence and solar flares?
The sun don't really need sunspots cause sunspots are related to several features on the sun's surface but prominences and solar flares need sunspots.Sunspots are the places where the magnetic field lines of the Sun poke out of the Sun to form loops.Where they poke out they are seens as prominences against the edge of the Sun's visible disk during an eclipse of the Sun.The looped magnetic field lines contain energy and are unstable, When they break and reconnect they release this energy suddenly and cause solar flares.
The first indication that the sun rotates?
We know it rotates about its axis because we experience day and night - phases through which we face the sun, then turn/rotate away from it.We know it rotates around the Sun because if it didn't, we'd fall directly towards it.We know the Earth rotates around the Sun and not the other way around because of inertia and angular momentum. Since the Sun is much larger than us, and therefore has hugely more inertia than us, we know that it must be sitting relatively still, for if it were to rotate around us, our gravitational pull would be insufficient to hold it in orbit. We must therefore be rotating around the Sun as it pulls us in to maintain our orbit around it.It is just as legitimate to state that the Sun rotates around the Earth at a speed of one revolution per 24 hours, which uses the Earth as a point of reference, assuming it is fixed and stationary in space with the rest of the universe moving around it.
Why is the sun spotty?
Sunspots are regions on the solar surface that appear dark because they are cooler than the surrounding photosphere, typically by about 1500 K (thus, they are still at a temperature of about 4500 K, but this is cool compared to the rest of the photosphere). They are only dark in a relative sense; a sunspot removed from the bright background of the Sun would glow quite brightly. The sun has a magnetic field that is twisted around inside the Sun as it spins. There are places on the sun where this magnetic field rises up from below the sun's surface and pokes through, creating sunspots. Sunspots are magnetic and often have a north and south pole like a magnet. They come and go over the surface of the Sun and last from a few days to a few weeks. The period of time between maximum outbreaks of sunspots is about 9 to 14 years, with an average of 11 years.
Are sunspots hotter or colder regions of the sun?
No, sunspots are cooler than the photosphere.
What are Areas of gas On the sun That cooler Then the gases around them?
Sunspots are areas of gas on the sun that are cooler than the gases around them.
What are cooler gases of the sun?
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.
Are sunspots darker and hotter than the gases surrounding them on the sun?
No, sunspots are darker but they are a couple degrees cooler, not warmer
Which pairs both occur as storm events on the suns surface coronas and prominences or sunspots and glowing gases or prominences and glowing gases or sunspots and prominences?
Sun spots and prominences.
How does the sun get sunspots?
Sunspots are cooler regions of the Sun's surface (they are still really bright, they just look dark compared to the surrounding Sun) they are caused by what are basically magnetic field "tangles" stopping the convection that brings heat to the solar surface.
What is an explanation of why sunspots appear dark?
The sun spots are the cooler spots. They are darker because there isnt much heat compared to the rest of the sun
What are patches of less hot gases in the sun's atmosphere called?
Patches of less hot goases in the photosphere are called sunspots.
Visible dark spots on the sun are called?
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.
What makes the sunspots?
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
What is the purpose of 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.
