What is a dark area of the sun that is cooler than the surrounding area?
A dark area on the sun that is cooler than its surrounding area is called a sunspot. Sunspots are temporary phenomena that appear as darker regions on the sun's surface due to magnetic activity.
What is a bright area on the surface of the sun called?
A bright area on the surface of the sun is called a facula.
What is a cooler area on the sun's surface?
An area on the sun that is cooler is called a sunspot.
What are dark spots on the suns surface?
The dark spots on the Sun's surface are called Sunspots. These are formed by the sun's magnetic field because these areas have less convection underneath the sun's surface. Convection is how the sun's energy gets to the surface from the core in a circular motion. This reduces the heat in the area and makes the area appear darker than the surrounding sun. However, these spots are still extremely hot and can be many times the size of Earth!
An area seen as a dark spot on the photosphere of the sun?
The darkest part, where the magnetic field is approximately vertical to the sun's surface is called the Umbra.
What is it called when the area of the sun is cold and darker that comes and goes in cycles?
This phenomenon is called a sunspot. Sunspots are temporary areas on the sun's surface that appear darker and are cooler than the surrounding areas due to intense magnetic activity. They occur in cycles of about 11 years and can have various effects on space weather.
What are dark areas on the surface of the sun?
Dark areas on the surface of the sun are called sunspots. They appear darker because they are cooler areas compared to their surroundings due to strong magnetic activity. Sunspots are temporary phenomena that can last from days to weeks.
What is a cooler area on the sun called?
A cooler area on the sun is called a sunspot
A dark area of gas on the suns surface that is cooler than surrounding gases?
The dark area is known as a sunspot on the Sun's surface. Sunspots appear darker because they are cooler than their surroundings. They are caused by strong magnetic activity that inhibits convection and reduces temperature.
What are the blotches on the Sun's surface that appear darker than surrounding regions?
The blotches on the Sun's surface that appear darker than surrounding regions are called sunspots. They are temporary phenomena caused by intense magnetic activity, which inhibits convection and reduces surface temperature. Sunspots are often associated with solar flares and coronal mass ejections.
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.
What is the darkened area of a sunspot called?
The darkened area of a sunspot is called the umbra. It is the central region of a sunspot where the magnetic field is strongest, causing the area to appear darker compared to the surrounding photosphere of the Sun.
