Sunspots are cooler, darker areas on the Sun's photosphere that are caused by magnetic activity inhibiting convection. They appear darker because they are about 1500 degrees Celsius cooler than the surrounding photosphere. Other areas of the photosphere do not have the same magnetic influence that creates sunspots.

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 best describes the photosphere?
The photosphere is the visible surface layer of the Sun and other stars, where light is emitted. It has a temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit) and appears as a bright, glowing layer. The photosphere is characterized by features such as sunspots, granules, and solar flares, which result from convective and magnetic processes. Overall, it serves as the boundary between the Sun's interior and the outer atmosphere, including the chromosphere and corona.
What is the function of the sunspot?
Sunspots can be defined as a short-term phenomenon on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They are caused by intense magnetic action, which inhibits convection by an effect comparable to the eddy current brake forming areas of reduced surface temperature. They usually appear as pairs, with each sunspot having the opposite magnetic pole to the other.
Sunspots are known to be magnetic phenomena because?
Sunspots are known to be magnetic phenomena because they are areas on the Sun's surface where the magnetic field is significantly stronger than in surrounding regions. This causes a suppression of convection, leading to cooler temperatures and darker spots on the solar surface. Sunspots often appear in pairs, with one spot having a magnetic field oriented in one direction and the other in the opposite direction.
What happens on the photosphere?
The photosphere is the outermost layer of the Sun's atmosphere where sunlight is emitted. It is the visible surface of the Sun that emits most of the Sun's light we see from Earth. The photosphere is where the temperature starts to decrease with increasing distance from the Sun's core.

What are dark patches on the surface of the sun?
They are called "sunspots". They are areas where concentrated tangled magnetic flux lines exit through the photosphere of the sun (locally cooling it, resulting in the dark appearance), propelling solar plasma outward as coronal loops (prominences), solar flares, and coronal mass ejections. Sunspots always occur in pairs, one being a "north" magnetic pole and the other a "south" magnetic pole.
Are the sunspots hotter or colder than the surrounding areas?
They are colder and darker than the other areas

How are sunspots and solar flares different from each other?
Sunspots are dark areas on the sun's surface caused by magnetic activity, while solar flares are sudden bursts of energy and radiation from the sun's atmosphere. Sunspots are relatively cooler regions, while solar flares are intense releases of energy.
Why do sun spots appear dark?
A typical spot consists of a dark region called the umbra, surrounded by a lighter region known as the penumbra. The sunspots appear relatively dark because the surrounding surface of the Sun (the photosphere) is about 10,000 degrees F., while the umbra is about 6,300 degrees F. Sunspots are quite large as an average size is about the same size as the Earth.
Why do sunspots appear dark in color?
Sunspots appear dark in color because they are areas on the Sun's surface that are cooler compared to the surrounding areas. This temperature difference causes them to appear darker when observed against the hotter background of the Sun.
Are sun spots hotter or colder than other parts?
Sunspots are cooler than surrounding areas on the Sun's surface, with temperatures around 4,000-4,500 degrees Celsius compared to around 5,500 degrees Celsius for the surrounding areas.
What do sunspots do?
Sunspots are areas of cooler and darker regions on the Sun's surface that indicate intense magnetic activity. They are associated with solar flares, which are sudden and intense bursts of energy that can release harmful radiation and impact Earth's magnetic field. Monitoring sunspots helps scientists understand solar activity and its potential effects on our planet.
Why do sunspots appear darker than their surroundings?
Sunspots appear darker than their surroundings because they are cooler regions on the sun's surface, which causes them to emit less light and appear darker in comparison to the hotter surrounding areas.
