Why are sunspots cooler than the photosphere?
Sunspots appear as dark patches in the solar photosphere. These are areas where strong magnetic field has emerged from below the solar surface. The strong magnetic field suppresses the release of heat into the photosphere making sunspots cooler than their surroundings.
Are sunspots cooler areas of the photosphere?
Sunspots. 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).
Are sunspots hotter or cooler than the sun?
Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun's surface. The temperature of a sunspot is still very hot though—around 6,500 degrees Fahrenheit!
Why are sunspots cooler?
As well as being a darker area on the sun, a sunspot is an area that temporarily has a concentrated magnetic field. This magnetic force inhibits the convective motion, which ordinarily brings hot matter up from the interior of the sun, so the area of the sunspot is cooler than the surrounding plasma and gas.
Why are sunspots cooler than the surrounding photosphere quizlet?
Explain why sunspots are cooler than surrounding areas on the sun's surface. Sunspots are cooler because there are areas of intense magnetism that are so intense that it inhibits the flow of hot gases from the sun's interior to its surface.
Why are sunspots cooler than the Sun?
As well as being a darker area on the sun, a sunspot is an area that temporarily has a concentrated magnetic field. This magnetic force inhibits the convective motion, which ordinarily brings hot matter up from the interior of the sun, so the area of the sunspot is cooler than the surrounding plasma and gas.
Why do sunspots increase temperature?
Times of maximum sunspot activity are associated with a very slight increase in the energy output from the sun. Ultraviolet radiation increases dramatically during high sunspot activity, which can have a large effect on the Earth's atmosphere. The converse is true during minimum sunspot activity.
How are sunspots different from the surrounding photosphere?
The photosphere is generally taken to have an effective temperature of 5800 degrees Kelvin. Sunspots are areas of the photosphere which have intense magnetic field activity which serve to reduce/disrupt the convection from lower in the sun thus lowering the temperature of the immediately surrounding plasma.
How does the temperature of a sunspot compare to the rest of the Sun’s surface?
Sun spots are magnetically disturbed areas on the surface of the sun that are actually cooler than the surrounding surface. The temperature of the sun's surface is about 5700 K or 9800 degrees Fahrenheit whereas the temperature of sunspots is closer to 4000-4500 K or 6740-7640 degrees Fahrenheit.
What is the relationship between Earth’s temperature and the number of sunspots that occur?
What is the relationship between Earth's temperature and the number of sunspots that occur? An increased number of sunspots causes an increase in Earth's temperature.
What is the relationship between Earth’s temperature and the number of sunspots that occur Brainly?
What is the relationship between Earth's temperature and the number of sunspots that occur? An increased number of sunspots causes an increase in Earth's temperature.
What is the relationship between temperature and the number of sunspots that occur?
What is the relationship between Earth's temperature and the number of sunspots that occur? An increased number of sunspots causes an increase in Earth's temperature. A decreased number of sunspots causes an increase in Earth's temperature.
