What else can I help you with?
Are sunspots permanent features?
Sunspots are not permanent features on the Sun. They typically last for days to weeks, and then fade away. The number of sunspots varies in an 11-year cycle known as the solar cycle.
What causes features on the sun?
Sunspots and other natural solar events.
The names of 2 types of solar features?
Two types of solar features are sunspots and solar flares. Sunspots are dark spots on the Sun's surface caused by magnetic activity. Solar flares are sudden bursts of energy and radiation released from the Sun's atmosphere.
What are some of the features that are on the surface of the Sun or above it?
sunspots prominence solar flares solar winds
What are the surface features of sun?
Photosphere- outer (gaseous) layer or surface of sun that we see Faculae- bright areas Sunspots- dark areas
Do sunspots occur on the surface of the sun?
What is true about sunspots
Features of the sun's surface?
Scientists have discovered many features of the sunâ??s surface. Some of these features include a rigid iron surface, sunspots, prominences, and solar flares.
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.
What are the most prominent visible features on the sun?
The most prominent visible features on the sun are sunspots, which are cooler and darker regions on the surface, and solar flares, which are intense bursts of radiation. Additionally, prominences are large, bright loops of gas that extend from the sun's surface into the corona.
What are the features found on the surface of the sun?
The most discernable features on the Sun are sunspots; areas that are a little cooler, and therefore a little darker, than the rest of the Sun around them. We know that sunspots are formed by intense magnetic regions, and that large solar flares and prominences are associated with sunspots. There's a cycle of increasing and decreasing numbers of sunspots that runs about 11 years in length, although this can vary by a couple of years. Slower cycles seem to be correlated with fewer sunspots, and faster cycles with more sunspots, but scientists don't have a detailed explanation for why the cycle exists, or why it is 11 years (more or less) in length. We are currently (in 2014) at or near the maximum of the sunspot cycle. You can see the daily view of the Sun and yesterday's sunspot number at the SpaceWeather website, www.spaceweather.com.

Are sunspots hotter or colder regions of the sun?
Sunspots are actually cooler regions on the sun's surface compared to their surroundings. They appear darker because they are areas of intense magnetic activity that disrupts the normal flow of heat to the surface.
