a)They are holes in the solar surface through which we can see to deeper, darker layers of the Sun.
b)They actually are fairly bright but appear dark against the even brighter background of the surrounding Sun.
c)They are too cold to emit any visible light.
d)They emit light in other wavelengths that we can't see.

solar spots are areas of quite ionized cloth it quite is not any longer in contact in nuclear fusion. they're arranged in strings like noodles in a pot. because of the fact the middle of the solar rotates swifter than the poles if those strings go the shear area of rotation they are able to be torn and the ends ensue to the exterior of the solar. there is usually a favorable and a unfavorable pair of sunspots-consiting of the alternative ends of the sheared string. they're very magnetic. a number of this magnitism outcomes the Earth ensuing in problems with satellite tv for pc and different varieties of communications. The spots ( or ends of the strings) are approximately 3000 stages cooler than the the remainder of the solar's floor and for this reason they're darker. solar spots have been studied for touching directly to the final 200 plus years. that's been desperate that sunspot interest will develop and then decreases over a 22 year cycle. The solar now at a low in sunspot interest.

The answer is B, they are bright but appear dark against the surrounding sun. They are magnetic storms which are cooler then the sun's photosphere. That's why they appear black. The sun gets even hotter and brighter the lower you go because it's closer to the nuclear furnace at the center of the sun.

The answer is c, they are to cold to emit visible light. Sun Spots are cold dark areas the sun gets. Usually it goes through a cycle where it gets more in a year than other years.

neither is correct. the particles that emite light that are ejected form the sun travel out of sunspots and then back into them as there is a loop in the suns magnetic field there.

The answer is b. They are hot gases but they are cooler than the background and hence appear dark.

"If you could cut an average sunspot out of the Sun and place it in the night sky, it would be about as bright as a full moon."

Answer b) is correct. I guarantee it. If you show a sunspot at its true brighness you overexpose everything else.

Sunspots are "dark" because they are cooler than their surroundings.
