The Role And Importance Of The Sun Philosophy Essay.
Sunspot, vortex of gas on the surface of the Sun associated with strong local magnetic activity. Spots look dark only by contrast with the surrounding photosphere, which is several thousand degrees hotter. The dark centre of a spot is called the umbra; the outer, lighter ring is the penumbra. Spots.
A sunspot is a region on the Sun's surface (photosphere) that is marked by a lower temperature than its surroundings and intense magnetic activity, which inhibits convection, forming areas of low.
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin. Sunspots have temperatures of about 3,800.
The Sun is such a massive source of energy and to be able to understand it more will help people to harness its power to meet the need for power and energy. Pete Interesting question, with its answer dating back to at least the 7th century BC when Greek scientists first started questioning the religious belief that the Sun was the god Helios, who each day would ride his fiery chariot across.
What are sunspots? Sunspots form on the surface of the Sun due to strong magnetic field lines coming up from within the Sun trough the solar surface and appear visibly as dark spots compared to their surroundings. These sunspots which can become many times bigger than the Earth are always dark because they are much cooler than the surrounding surface of the Sun itself. A big sunspot can have a.
The Sun so greatly dominates the skies that the first scientific speculations about different climates asked only. Speculation increased in the mid-19th century following the discovery that the number of spots seen on the Sun rose and fell in a regular 11-year cycle. It appeared that the sunspots reflected some kind of storminess on the Sun's surface — violent activity that strongly.
Sunspots are connected with other solar events like flares and coronal mass ejections (CMEs). A solar flare is a sudden release of energy from the sun, while a CME actually shoots hot plasma from the sun into space.The precise mechanisms that trigger flares and CMEs are not yet known, but the bigger the group of sunspots, the more intense such solar weather tends to be.
