Why are sunspot darker than surrounding areas?
Sunspots are darker because they are cooler than the surrounding area.
Why are sunspots colder than the surrounding areas?
Slower convection means that less gas is transferring heat from the core of the sun to the photosphere.
Why do sunspots look dark in color?
In regular photographs, sunspots appear dark because the temperature of surrounding areas is so high that by comparison, sunspots are cool. In reality, they are still immensely hot.
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.
What causes sunspots to be colder than the surrounding areas?
Sunspots are areas on the surface of the sun where strong magnetic fields keep charged particles trapped. Matter on the surface convects (gets heated, rises to the surface, cools, and sinks down only to be reheated and continue the cycle) but not the matter trapped in these magnetic fields. It can't sink back down once it cools off, which is why it looks black from Earth. These spots are still 3000 degrees kelvin (essentially Celsius) which is really hot but colder than the surrounding 5800 kelvin surface.
What is a dark area on the surface of the sun that is cooler than the surrounding area?
Sunspots are dark areas on the sun's surface that are cooler than the surrounding area.
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 is the flow of heat through a material from areas of hotter temperatures to areas of colder temperatures?
Convection I believe. If not conduction. I'd go with convection.
Why some areas are colder?
depending on the climate different areas can be colder or hotter. closer to the equator will be warmer and likewise farther from the equator will be colder but besides that u have to factor in the height of the land and the usual weather those are all factors of the climate or the "area"
What best explains the movement of heat from tropical to polar areas?
The fact that heat tends to move from hotter objects to colder objects.
Is Alaska desert hotter than Arizona?
Alaska has no major true desert areas but if it did, they would be much colder than Arizona.
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.
