What is the significance of sunspot regions the sun?
A sunspot is a part of the Sun that is cooler, and therefore darker, than the surroundings.
What blotches on the Sun's surface that appear darker than surrounding regions?
sunspots
Sunspots are what compared to the gases around them on the sun?
Sunspots appear darker because they are "cooler" than the surrounding area.
What a sunspot is?
A sunspot is an area on the Sun's surface (the photosphere) that is affected by intense magnetic activity, which inhibits convection, thus reducing the surface temperature in that region. Even though sunspots are still very bright and hot they appear darker because they are cooler than the surrounding area. The normal temperature of the photosphere is about 5,800 kelvin, whereas the temperature of a sunspot is roughly 4,000 - 4,500 kelvin, which leaves them clearly visible (through filters) as dark spots. The average sunspot is about the size of the Earth! However, sunspots come in a variety of sizes ranging from hundreds to tens of thousands of miles across (many times larger than Earth). Scientists measure the total size (area) of all of the sunspots seen on the sun every day to get a measure of how active the sun is. Sunspots are not permanent. They appear and disappear on the surface of the sun in regular cycles that average about 11 years.See the link below for more information

Why are sunspot dark?
Sunspots aren't actually dark, if you could look just at a sunspot it would still be bright enough to damage your eyes. They are however, significantly darker than the surrounding Sun, which makes them appear black. Sunspots are darker than the surrounding Sun because they are cooler areas. What happens is a "tangle" of magnetic field stops the convection bringing new hot plasma to the surface, meaning the area inside the tangle keeps cooling, we can't see magnetic field lines, so what we see is the cooler region of plasma.
What are dark areas cooler than their surroundings?
sunspot
Why are sun spots darker than the surrounding area?
They are darker because they are relatively cooler than the surrounding area. They are cooler because where a sunspot happens tightly bunched together magnetic field lines poke out of the surface of the Sun. This region of intense magnetic activity, inhibits convection motion and thus less heat is welling up from the Sun's interior.
A dark area of gas on the suns surface that is cooler than surrounding gases?
It is called a sunspot.
What is suns spots?
A sunspot is a dark spot on the sun's surface. It is darker because it is cooler than most parts on the sun.
Why is part of the sun black?
No part of the sun is black. There are anomalies called sunspots which are cooler than the surrounding areas that appear darker but they are still incredibly hot and are not black.
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
Why do the sunspots appear to be darker than surrounding part of the sun?
This is because they are cooler.
What blotches on the Sun's surface that appear darker than surrounding regions?
