Sunspots are temporary phenomena on the surface of the Sun. The number vary over time, but there is a "trend" towards a greater number appearing every eleven years. However, this "trend" seems to be "disturbed" as the "11 year" cycle is very late.

What is true about sunspots


Describe the characteristics of sunspots?

A sunspot is a region on the Sun's photosphere that is cooler and darker than the surrounding material. Sunspots often appear in pairs or groups with specific magnetic polarities that indicate electromagnetic origins.


What part of the sun does storm clouds occur in?

I assume you are talking about sunspots, as they are, in effect, "storms on the sun". They occur on or near the sun's surface.


Which layer of the sun do sunspots occur?

They appear in the Photosphere. That's basically the "surface" of the Sun.


Sunspots are temporary disturbances in the sun's?

Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.


Which layer of the sun do sunspots occur on?

I believe that the layer in which sun spots occur would be the chromosphere. The chromosphere is the second layer in the sun's atmosphere and is about 2,000km above the photosphere(the first layer).


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.


Which pairs both occur as storm events on the suns surface coronas and prominences or sunspots and glowing gases or prominences and glowing gases or sunspots and prominences?

Sun spots and prominences.


What are dark areas on the photosphere on the sun called?

Dark areas on the photosphere of the Sun are called sunspots. They appear dark because they are cooler regions compared to their surrounding areas, which results in decreased luminosity. Sunspots are temporary phenomena that occur in 11-year cycles as part of the Sun's magnetic activity.


Sunspots sit on the suns what?

Sunspots sit on the sun's photosphere. The photosphere is the surface of the sun, and sunspots are dark regions on it that are visible. The photosphere's average temperature is about 5800 degrees Kelvin.


Where do the sunspot appear?

Sunspots appear on the surface of the Sun, specifically in the photosphere. These darker, cooler areas are caused by magnetic activity on the Sun's surface. Sunspots can vary in size and shape and are often seen in groups.


What structure found in the photosphere?

Sunspots are structures commonly found in the photosphere of the Sun. These dark regions are caused by magnetic activity and are cooler than the surrounding areas, hence appearing dark against the brighter photosphere. Sunspots often occur in pairs with opposite magnetic polarities.
