how water affects world wide climate?

You need to concentrate your answer in the following areas:\n\n1) The effect of oceanic circulation.\n2) The role of water vapour as a greenhouse gas.\n3) The role of water as ice and cloud in increasing albedo\n4) The role of water in oxygen production, and hence the effect of oxygen on climte.\n5) The effect of life on albedo.\n6) The role of oceans as heat sinks and atmospheric buffers.\n\n\nWater also has a lot of small scale effects on climate of course, but I'm assuming you really do mean global climate.\n\n\n\n>>>>> countries which are surroended by large bodies\n>>>>> of water have more amount of rainfall than those \n>>>>> countries who are surrounded by land.\n\nNot at all. Australia and the Galapagos islands for example are surrounded by large bodies of water and both are primarily desert. Likewise Antarctica is surrounded by large bodies of water and is the driest place in Earth.\n\nIn contrast Switzerland and Paraguay are both completely landlocked countries that recieve large amounts of rainfall.\n\nWhile it is very broadly true that rainfall decreases with distance from the coastline there is ismply no way to extend this to making comparisons between countries or regions. Many coastal regions are far drier than many central continental regions. Ther are just  too many factors at play to make generlistaions about the effects of oceans on rainfall.

The earth is protected by the Ozone Layer, which helps us from the sun's damaging uv rays.  As people pollute the air, the ozone layer becomes damaged and evenutally will diminish causing the sun's damaging rays to enter the earth's atmosphere increasing temperatures.  The increase in temperature would cause areas of extremely cold temperature where icebergs are found to become warmer; thus causing icebergs to begin melting.  The increase in temperature will also cause many of the plants that survive and grow in the tropics to die.\n\nAir pollution contribuites to GW by causing the ozone layer to dissapear, leaving sections of "holes" where the powerful ray's of the sun will cause increase in temperatures damaging life forms to include plants, animals that survive on such plants, polar caps melting which could affect the animals (polar bears, penguins, etc).

1. continental drifting\n\nVery slow but substantial changes.\n\n2. changes in sun's energy\n\nSuspected to be large, but not yet demonstrated conclusively.\n\n3. variations in the positions of the earth relative to the sun\n\nFairly small effect. \n\n4. volcaic eruptions\n\nLarge observable effects in global temperature etc. \n\n5.greenhouse effect\n\nKeeps the earth about 60 degrees F warmer than it would be otherwise.\n\n6. global warming\n\nIn the last hundred years, the earth has warmed measurably. It is not clear if this is due to human activities or not, but many suspect it is.\n\n7. air pollution\n\nHas increased the ozone depletion at the poles in springtime, which introduces more UV lower into the air column. This might be changing the climate, although it is not known for sure.\n\nAlso blocks sunlight locally near sources of soot. It is not clear how big an effect this has globally, but it might be a cooling factor. \n\nAcid rain produced by S02 emissions has been involved in some deforestation, which has probably had an effect on the climate, but again this is not known for sure.

I give you a couple of hints:\n\nThe sun radiation heats Earth´s surface generating a  movement of air due to the phenomenon of convection: hot air (near the surface) goes up while cold air (high layers of atmosphere) goes down. The air can be wet of dry depending the zone that is heated by the sun (most of the water in atmosphere results from the evaporation of oceanic masses when sun radiation hits the superficial waters for example). \n\nNormally, hot and wet masses of air travel to the North of the planet while the cold and dry travels to the south hemisphere. The encounter of these masses can cause violent hurricanes in some zones of the planet, droughts in others and heavy rains in some others.\n\n(If you need more information I have to tell you that you should travel to www.wikipedia.org)\n\nHope it helps you!\n\nGood luck!

The degree to which humans are effecting the climate is unclear.  There are so many variables that even the most powerful computers or networks of computers can't effectively model them all.  Even if there were computers powerful enough, the honest answer is we don't understand enough about the world around us to know how each system effects the other.\n\nLooking back further than the VERY short timespan that humans have kept climate records, we see that in the past the world has been much much colder during certain periods, but also much, much much warmer during others.  We are now in what you would call "Ice House" conditions, where we cycle between long (100,000 year) glacial periods, and relatively short interglacial (~15,000 year) periods.  Right now we're sitting 2/3rds of the way into one the interglacial periods.  The slight fluctuation that is occuring now may be related to humans, or may be part of the natural cycle.  In any event, it has occured before, when there was no more human CO2 contribution than from campfires.\n\nAll this getting colder stuff happened when the space betwen North and South America closed off, which was once what was called the "Isthmus of Panama".  Before then, times were much much hotter, and correspondingly sea levels were higher too.  This was because the water could go around the equator and exchange hot water from Pacific to Atlantic.  Now, the only seawater exchange is North-South, and around the poles, so you can imagine that this would tend to act to depress temperatures.\n\nAnyways, long story short: We don't really know.  Personally, I think we should worry less about this global warming stuff, and more about reducing air and water pollution and dealing with the increasing water shortages around the world.

Global warming melts the polar icecaps which dilute the salinity of the water. In a process we don't fully understand yet, this slows down the circulation of the undercurrents. \n\nThe earth is in a delicate climatic balance. One of the beneficial effects of "bad" storms(such as hurricanes) is that they act as an equilibrium- bringing cooler air towards the equator and warmer air towards the poles. If this is upset, the results often bring wild swings. \n\nSo if the pendulum swings too far, it could swing too far the other way.

Also pressure from cold water sinking in some areas, thus causing it to rise in others, such as the Peruvian coastline (produces La Niña), the ac5tion of prevailing winds on both warm and oold surface waters.  Also water entering the oceans from large rivers such as the Amazon and Mississippi, and also salt concentration (dense water sinking).\n\nTidal currents are caused by the combined effects of the sun and the moon, the strongest when their effects combine.\n\nHeat and cold also affect water density, causing the ocean suface to be higher in hot areas and depressed in cold areas.\n\nGenerally these effects keep water circulating.  Some lack of movement is possible where all are missing from a given area, such as the Sargasso Sea.

That's really a very interesting question.  The short answer is that the water evaporates rises to form a cloud and drifts somewhere else (over land, lake or ocean) to fall as precipitation (rain or snow, etc.) returning to where it began but in a different spot upon the planet.  And don't forget that some of the water is broken down in plants to form hydrocarbons (perhaps the wood of a giant sequoia tree).\n\nThe fascinating answer is that some of the precipitation falls at the poles and is locked up for centuries within mile thick glaciers.  Some of the rain drifts to the poles with salt water and is chilled so cold it sinks to the bottom then finds its way to the seven seas in very cold currents that finally wend to the tropics and rise to replace evaporated seawater.  The bottoms of the oceans even at the tropics is dark and icy cold and the entire cycle from pole to tropics and back to the atmosphere can take centuries.  Some of the precipitation can drain into underground rivers and even refill huge aquifers that underlay many contiguous states.  The water in many aquifers has been there for centuries (even since the last glaciers retreated).  Although everything remains in a vague equilibrium (perhaps interrupted by ice ages) a drop of water that evaporates may be taken out or the normal water cycle for hundreds of years at a time.

The melted ice cube does affect the water level. Global warming is causing the sea level to rise because the polar ice caps are melting and adding to the amount of liquid in the sea.

It has EVERYTHING to do with climate, season, winds, etc.\n\nThe Coriolis effect, which results from the Earth’s rotation, plays an important role in large-scale circulation of the atmosphere. As viewed by an observer on Earth, air appears to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This results in areas of low pressure rotating counterclockwise in the Northern Hemisphere and clockwise in the Southern hemisphere, with the opposite being true for areas of high pressure. If the Earth’s rotation were to suddenly reverse itself, these patterns would also be reversed. The westerlies would become easterlies and the northeast trades would blow from the northwest. \n\nChanges in the Earth’s rotation would have an effect on ocean currents, which can influence local climates. The El Niño and La Niña phenomena that affect global climate patterns on a periodic basis. \n\nOne large component of a location’s climate that would not likely be affected would be the effect of seasons, which are more dependent on the tilt of the Earth’s axis than they are on the Earth’s rotation.

The water cycle is usually broken into 4 basic steps:\n1) evaporation / transpiration / sublimation\n2) atmospheric storage\n3) condensation / precipitation\n4) runoff/infiltration / surface storage\n\nThere is as much water on the planet today as there was when dinosaurs roamed the Earth. There will always be plenty of water.\n\nNow, if we are talking about useful water, we need to reexamine this. You may first want to look at NASA's global water map:\nhttp://www-surf.larc.nasa.gov/surf/pages/water.html\n\nNASA also has a page for global water distribution:\nhttp://earthobservatory.nasa.gov/Library/Water/\nThis page illustrates the tiny portion of useful water on our planet.\n\nThere are two larger issues that NASA does not discuss in their global water distribution. 1) Keeping in mind that the US has just about the same amount of water available as it did 200 years ago, there are now 250 million to share with instead of the 4 million of 200 years ago. 2) Of the roughly 3/4% of fresh water in groundwater and lakes and streams around the world, much of that is too polluted to drink.\n\nWith regard to the coming urgency for "Thinking Globally - Acting Locally", check out Jonathan Harris' "infographics" poster:\nhttp://www.princeton.edu/~ina/infographics/water.html When our neighboring countries run out, they will be forced to do what you do when you run out of sugar in the middle of a recipe - run over to the neighbor's for some.\n\nWhen we waste water, we are not only using our drinkable water but we are also moving water to the undrinkable part of the water distribution. True, we aren't losing any water on this planet, but we are losing useful water and won't be getting any more new water, either.\n\nIf we do, it will be in the form of a large icy comet and we probably won't need water at all after that.

There's actually a number of reasons why water does that. Yes, cooler or warmer water can come in and make water differ in temperature in different parts of the body of water. Another reason is that water takes a lot longer to cool or heat than many other things like the earth. The depth of the water makes an impact also. The sun's rays passing through the water faster at different depths heat water when it's not as deep.

The human race will survie with great difficulty. The average temprature of earth will plumit to near Zero degrees. World Strom Systems will become depleted of Water vapours thus creating huge famine all over the world.

Because it takes a tremendous volume of water to rise the oceans even by inches and much of the water will cycle, evaporating, forming clouds and comming back down as rain, with part of that being absorbed drunken by plants and other life forms.
