Describe the sunspot system.?
461611
The sunspot cycle is caused by irregularly shaped magnetic field lines caused by differences in rotation speed of the surface of the sun and they are also caused by electrical currents caused by the effect of the suns natural magnetic field on the plasma in the surface and corona of the sun. The sunspots are auctually cold spots on the suns surface that are caused by the magnetic field lines repelling charged plasma on the suns surface.

Sunspots are places where the sun's magnetic field has "kinked" and is poking upward above the sun's surface.  They are darker because they are cooler than the surrounding regions.  The gas is cooler because the magnetic "cork" blocks energy from flowing upward.\n\nThe kinks in the magnetic field happen because the sun is a "ball of gas" and does not rotate at the same rate at all latitudes.  Regions near the equator rotate faster than regions near the poles.  The magnetic field is dragged along, causing it to wind around the sun and developing the kinks which cause sunspots.

The sun is the center of the solar system, revolving around it are the nine planets namely: mercury, venus, earth, mars, jupiter, saturn, uranus, neptune and pluto.

the Sun,and the earths Bio-mass.\nthe sun makes it hot (you may know that already)\nand the trees(bio-mass) absorb heat and release it .\nso regulating temperatures between day and night.\nthe ozone layer and aquifiris manta(atmosphere ,clouds,mist etc.)\nworks as a filter and determines how much sun(heat)is allowed to enter.

The sun, moon, planets, I guess this is about all I can think of!

The Earth rotates on its access and revolves around the Sun.

- The Sun is so large, you could fit over one million Earths inside it.\n- The Sun consumes four million tons of hydrogen every second. Even so, it's so vast that our star has enough fuel to keep it shining for another five billion years.\n- The Sun's energy output is estimated to be 386 billion, billion megawatts. So in 15 minutes our Sun radiates as much energy as mankind consumes in all forms, during an entire year.\n\n- The sun is fascinating ! :)

Quite simple, though not simple to explain.\n\nWind :- The Insolation (INcomming SOLar radiATION), from the sun (tortology - sp?, i know) warms up the ground ou ocean. These bodies radiate heat in the form of infra red radiation which in turn heats up the atmosphere. The hot air rises and as it does, cooler air flows across the surface to replace the air that rose. Ari flowing across the surface is wind.\n\nOcean currents opperate in a similar fashon.

When the Sun has Sunspots you can see that they revolve around the Sun.\n\nIt basically rotates similar to how the planets rotate.\n\nRotate not orbit.

I derive essentially the same function as you do:\nf(x) = 70+50*cos(((2*pi)/11)*(x-1))\n\nThis function is the actual function of sunspot activity with the first maximum occuring in year 1 and maximums occuring every 11 years thereafter including 1750 and 1948.\n\nThe reason your calculator is giving you wrong results is that it is in "degree" mode rather than in "radian" mode. (Don't feel too bad, it took me almost an hour to figure out I had my calculator in the wrong mode too.)

Hi, \n\nThe sun's orbit is 365.4 days. The actual length changes very little, but with a period of roughly 41,000 years.\n\nHope that helps, \nMatt

1.Sunspots and Solar Flares are two "surface features".\nsunspots are created due to intense magnetic emissions, which lower temperature and prohibit convection, the transfer of heat through fluids (liquids and gases)\nSolar Flares are violent explosions within the atmosphere of the sun, which eject superheated plasma at over 1 million miles an hour. the flares also emit all forms of electromagnetic radiation, from short wave gamma radiation to long wave radio.\n\n2. Up until the mid-19th century, the light parts (terrae) and dark parts (mare) were thought to be land masses and oceans respectively.\nA theory propagated in Nazi Germany was that the moon, and other celestial bodies, were made of ice.\nUp until the 1950's, it was not completely accepted that the features of the moon were impact craters. Now we know that they truly are craters left over from meteor impacts, the youngest of which are hundred of thousands to millions of years old.\n\n3. What Shoemaker meant was, that since the Moon has no atmosphere, there is no chance of erosion or weathering affecting the features.\nCraters and debris pile up, never changing, just being overlapped by newer events.\n\n4. "Sunshine" Is called an Exothermic thermonuclear reaction (nuclear fusion). The exothermic fusion events happen in the core, where hydrogen is converted into helium, helium into carbon, and carbon into iron.\nThe heat energy created by fusion in the core then travels trough the rest of the layers of the sun before escaping as light and other forms of energy.\n\n5. There is a large amount of Iridium found in the fossil layer of around 65 million years ago, and Iridium (very rare on Earth) is abundant in asteroids.\nChicxulub Crater is an ancient impact crater buried underneath the Yucatan Peninsula. Geologic studies have found that the age and chemical composition of the crater corresponds with the hypothesized asteroid that hit Earth 65 million years ago.\n\n6. The moon is tidally locked in orbit around the Earth, so that as it rotates, we rotate, so that the same face is always pointing toward us. The moon rotates and orbits completely around the Earth every four weeks, so that is why we never see the far side. \n\n7. Mercury and Pluto would have the most in common with the Moon, due to their lack of atmosphere. Mars is semi-similar to the Moon, due to the lack of water available to erode the topography.\nEarth and Venus are the least like the Moon, due to their rather violent atmospheres.\n\n8. Contrary to popular belief, the Earth is NOT closer to the sun, any time of the year. Its orbit is described as elliptical, but only because it is not a perfect circle.\nSince the Earth is tilted, currently in Washington it is autumn, but it is spring in Australia.\nThe Northern Hemisphere is angled so the suns rays are less direct in hitting the face of the planet, and the Southern Hemisphere is angled so the rays are more direct.
