what does the sun do in the   in the water cycle?
476577
Evaporates water back into the sky so that it can come back to the earth in the form of percipitation.

The Sun is mostly hydrogen and helium, but also contains wery small quantities of lots of other elements such as oxygen, magnesium and iron.

In the surface of the sun, the hydrogen and helium are get reacted and generate the heat energy. This power is a main reason to sun is very hot. Due to cenre of gravity all bodies get link with sun and rotate.

The sun.  That's what Mother Nature used, and it works pretty good.

This question could be interpretted two different ways: (1) What drives the sun to produce heat/enegery? and (2) Describe the process of using the solar energy to power modern conventions.\n\nSomebody else already attempted the latter, so I'll go for #1.\n\nThe sun, right now, is fusing hydrogen into helium to produce its energy.  It's been doing this for a long time, and will continue to do so until it runs out of hydrogen.  When this happens, it'll start fusing the helium, and so on.\n\nHope this helps.

The heat and light in the sun is due to the vast amounts of energy produced at the core. At the core hdrogen atoms combine together to form Helium atoms due to the pressure (billions of atmospheres.) and temperature (15 million degrees C). This reaction is called fusion. \n\n  However the mass of the helium atoms produced is slightly less than the combining hydrogen atoms. This difference in the mass is coverted into energy according to einsteins equation E= mc2 (c is squared).\n  This energy is in the formed of gamma rays which reaches the earth. However what we look at is only the surface of the sun called the "photosphere" which is very much cooled than the core (just 6000 degrees).\n\nThe sun wont always be bright. Eventually as the hydrongen gets used up, the reaction will slow down and the sun will become a red giant and on further reduction will become a white dwarf and at the end it will be a black dwarf.

It would be heat and sunlight- A cycle means that a substance or energy will eventually return to its origin.  Sunlight generates heat and chemical energy on the Earth, but is non-cyclic, in other words, you have to have a constant infusion of it all the time, it doesnt recycle.  The majority of the energy of sunlight is lost as heat, out of our atmosphere into space, never to enter the cycle again. So the flow would be sunlight in, some chemical use and some heat absorption, and eventually all the energy is lost as heat out.

Sun Spot Cycles, or Solar Cycles, Affect Earth’s Weather  \n\n \n\n\n \n\n\nSun spot cycles are being studied by various scientific organizations which publish regular reports on their findings: the Sun has cycles of activity and inactivity, characterised by more or less sun spots, flares and other signs, and these cycles have an effect on radio communications, power distribution and even the weather on Earth as well as on orbiting spacecraft.\n\nSun spots are relatively cooler areas on the Sun that are observed as dark patches. \nThe number of sun spots observed indicates the amount of activity and the length of the solar cycle under observation. A great deal of research focuses on trying to predict sun spot activity and recently, scientists at NASA’s Marshall Space Flight Centre reviewed all the current methods. They recommended combining the two best methods, which both use disturbances in the Earth’s magnetic field as an indication of ‘solar maxima’, when the Sun is most active. Magnetic activity that accompanies the sun spots produces changes in the ultra-violet and soft x-ray emissions from the Sun with consequences for the Earth’s upper atmosphere.\n\n\nIt was Galileo, in 1610, who made the first European observation of sun spot activity. Later that century there was a period of inactivity, with very few sun spots reported from about 1645 to 1715. This inactivity corresponded with a period of colder weather on earth, with year-long snow at lower than usual altitudes and rivers freezing over - out of character. \n\nDaily observation began at the Zurich Observatory in 1749. Details of observations of sun spots – their number, size and position – have been recorded by the Royal Greenwich Observatory since 1874. US Air Force data have been added to that observatory’s records since 1976. Daily updates on the sun spot cycle and monthly updates on sun spot cycle predictions are published on the internet. \n\nRegular observation of solar activity has shown that sun spots are concentrated in two bands around the Sun. Tracings of sun spot positions reveal a shape that is referred to in the name of a ‘butterfly diagram’ of activity. Sun spots group together in clumps of around 10 spots. Monthly data reveals that the number of spots visible waxes and wanes in a cycle of about 11 years. The more scientists can learn about sun spot cycles, and predicting them, the more we will know about how the Sun works. \n\nSolar cycles of activity and inactivity, characterised by more or less sun spots, flares and other signs, are important to us on Earth and regular reports on scientific findings of observations of sun spot cycles are published on the internet.

the sun doest not use oxygen. it actually follows a method called nuclear fusion, whereby two hydrogen atoms react to form a helium atom. with this, very large amounts of heat and light are produced

Sunlight, H2O (water), CO2(carbon dioxide)??

The Sun, in 4.5 billion years supposedly, WILL start to swell. It will get bigger, and en-gulp Mercury and Venus. The atmosphere will evaporate, water will melt, and life will be gone. The sun will swell enough to devour the earth, then shrink, grow, Turn into a planetary nebula, then shrink, for the last time, into a white dwarf. Then In a few billion years, cool down to a black dwarf.\n\nThe reason the sun expands, In case you want to know, Is because of its fuel supply. The energy from the sun comes from nuclear fusion of Helium. When the helium supply runs out, The sun has to fuse hydrogen, therefore making the sun swell. The sun then will Shrink, once its helium supply is restored, grow again, then cast out a planetary nebula (For what a planetary nebula looks like, Look up the ring nebula) then it wont have enough hydrogen to grow back to the normal size...and become a white dwarf. Eventually, it will cool into a black dwarf and die.

morning.  because water + sun = food (for plants) water them int he morning

It absorbs light energy from the sun.

the water cycle is what it says it is,the cycle water goes through.there has always been the same amount of water in the earth at all times.basically it is recycled.water from bodies of water is evaporated and rises into the atmosphere.it isnt all H2O.it contains all of the impurities and other elements also.the partcles form clouds and when they get heavy enuogh it rains.but it isnt just rain from the beginning.as it falls ,it starts out as frozen water(snow)and as it falls toward the earth,it melts into raindrops.i hope this helps.

The sun causes the water to evaporate leaving the salt behind.
