What are sunspots caused by?
Sunspots are caused by interactions between the Sun's magnetic field and its plasma. Magnetic field lines become twisted and concentrated, inhibiting the flow of energy from within the Sun, resulting in cooler and darker regions on the surface known as sunspots. These sunspots appear darker because they are cooler compared to the surrounding areas.
What are the dark spots on the surface of the Sun that represent areas of cooler temperatures called?
The dark spots on the surface of the Sun that represent areas of cooler temperatures are called sunspots. Sunspots are regions on the Sun's photosphere that appear dark because they are cooler than the surrounding areas, due to intense magnetic activity inhibiting convection. Sunspots are temporary phenomena that occur in cycles and can have significant effects on space weather and Earth's climate.
Sunspots are dark because?
Sunspots are dark because they are cooler than the surrounding area on the Sun's surface, known as the photosphere. The magnetic fields near sunspots inhibit the flow of hot gases from below, causing them to be cooler and appear darker in comparison.
Why do the amount of sunspots change over time?
sunspot: A spot or patch appearing from time to time on the sun's surface, appearing dark by contrast with its surroundingThey appear because of strong magnetic forces on the sun. Our magnetic forces are changing on earth too.
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.

Do sunspots occur in magnetic pairs?
Yes, sunspots typically occur in pairs with opposite magnetic polarities. This is known as Hale's polarity law. Sunspots are regions of intense magnetic activity on the Sun's surface, and the interaction between these magnetic fields gives rise to the characteristic dark spots we observe.

How will sun spots effect the earths weather?
Sunspots: One interesting aspect of the Sun is its sunspots. Sunspots are areas where the magnetic field is about 2,500 times stronger than Earth's, much higher than anywhere else on the Sun. Because of the strong magnetic field, the magnetic pressure increases while the surrounding atmospheric pressure decreases. This in turn lowers the temperature relative to its surroundings because the concentrated magnetic field inhibits the flow of hot, new gas from the Sun's interior to the surface. Sunspots tend to occur in pairs that have magnetic fields pointing in opposite directions. 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 Eart
What are dark patches on suns surface?
Dark patches on the sun's surface, known as sunspots, are areas of reduced temperature caused by magnetic activity inhibiting heat transfer. They are temporary phenomena that appear darker than their surroundings due to their cooler temperatures. Sunspots are associated with increased solar activity and can impact Earth's space weather.
Why does the number of sunspots vary?
The number of sunspots depends on the magnetic field of the Sun. This magnetic field changes with a period of roughly 22 years; twice in each of these magnetic cycles there is a maximum of sunspots. (So, the sunspot cycle has a period of about 11 years (on average), whilst the magnetic cycle has a period of about 22 years.)I am not sure whether the reasons for the magnetic cycles are completely understood, but you can check what is known so far, in the Wikipedia article on "Solar dynamo".
What is the dark patches on the sun's surface?
Dark patches on the sun's surface are known as sunspots. They appear darker because they are cooler regions on the sun's surface where magnetic activity inhibits the flow of heat. Sunspots can be large and can last for days or weeks before dissipating.
Why do solar flares happen near sunspots?
Sunspots are believed to be the sites where solar flares are generated. Sunspots are known to be "storms" on the sun's surface, but they are not yet fully understood.add The surface of our Sun is about 5800 deg C and above, and naturally most of the material is highly ionized. Thus large electrical currents may be generated, and these in turn cause the magnetic field loops seen as solar activity. These magnetic loops can accelerate the charged ions from the Sun, hence the name Solar Flare..
What are the dark spots on the photosphere?
Dark spots on the photosphere, known as sunspots, are areas of reduced surface temperature caused by magnetic activity on the Sun. They appear darker than their surroundings because they are cooler and emit less light. Sunspots can vary in size and number over an 11-year solar cycle.
