the water is warmer then the air and it works the same way breath on a glass window fogs up. the moisture in the air condenses and rises, but this only happens when it is cold or early morning, only when the air is colder then the water.

Water (rain, snow, dew, ...) which ends up higher than sea level will flow toward the sea if there is any possible path. Since even a mountainous 'bowl' is likely to have a porous bottom, or to fill enough to find an outlet, there will almost always be a flow to lower levels. \n\nFlowing water is not a neglibible force. It will, over geologic time move, dissolve, pulverize, and remove material. Freeze/thaw cycles contribute more than a bit; the Old Stone Face in new Hampshire in N America has recently fallen (literally) to this. Some of that material will be dropped downstream, filling in an existing channel. Spring floods (in places in which snow and ice accumulate on high ground) will provide an annual increase in this erosion, and if they break over channel banks, will accelerate the deposition process (eg, the Nile floods until the installation of dams to stop them). \n\nOver geologic time, a stream (or river) will fill channels repeatedly and will find new flow paths after doing so. What with dumping material from higher levels, and doing it in channels here and there across the gap between highlands, there will be a gradual acretion of soil in that gap. \n\nEventually, the flowing water, combined on occasion with wind and plant and animal soil processing (earthworms, for instance), there will be a more or less level filiing of the gap between highlands, with water flowing across it on the way to the sea. \n\nThat space, with a history more or less as sketched is a valley. Tehy can be narrow (a kilometer or less) or wide (several hundred kilometes). In fact, they can be so wide that it's not possible for a human to see both highlands between which the water flows at the same time. Valleys can also be very long if the highlands are arranged to permit. Consider the Nile, the Danube, the Volga, the Mississippi, or the Ganges. \n\nIn short, highlands erode, flatten out, and fill in the gaps between them. This can be seen in Britain (whose hills and mountains wer once higher) and in the North American Appalacians (whcih were once very very impressively tall). The N American Rockies, S American Andes, and Asian Himalyas are examples of the early stages in this process. Some millions of years hence, all three of these mountain ranges will be much lower and rounder.

Depends on the building, but the actual pump is often supplied by the fire engine.  The water pipes are usually in the stairwell or just outside the stairwell.  Some buildings have their own water pumps in a basement or adjacent facility, but this can cause problems if the building is on fire.

Some models in addition utilize compressed air to atomize  the water.  Most though simply utilize fogging high pressure mist into freezing air.  Collision in the air of two streams of water is another means of breaking the water into small dropletts which will freeze before hitting the ground, this actually requires less energy on the parts of the electric pumps ie lower pressure and higher volume of flow.

You can observe this yourself by breathing on a mirror. As the condensation evaporates from the mirror, you have completed the water cycle. Water evaporates into the atmosphere from the ocean, lakes, rivers, and from soil and plants, and even from your skin and breath. When the air reaches saturation (100% humidity) due to cooling or changes in atmospheric pressure (or both) the water condenses from vapor to liquid (or solid) and falls to earth as rain, snow, sleet, hail, or maybe only as dew. This water may then form streams and rivers and return to the ocean where it may evaporate again into the atmosphere or it may sink into the earth where it becomes groundwater that may take many thousands of years to emerge again, or may be pumped to the surface from a well and used for drinking water or irrigation. It is a continuous cycle that may take only seconds or may take thousands of years to complete the cycle depending on the path of the water.

I'm not sure what water tanks you are asking about.  I'm going to guess that you are referring to city water systems with towers holding large water tanks.\n\nThey are filled by pumps.  Wells are drilled and the water is pumped from them to these large tanks.  From the tanks gravity moves the water throughout the community to meet demand.

The maximum water level is called "high tide" or "high water" and the minimum level is "low tide" or "low water". High water occurs as two bulges in the height of the oceans; one bulge faces the moon and the other, on the opposite side of the earth, faces away from the moon. For an explanation see below under Tidal physics. There are two low waters positioned at about 90° of longitude from the high waters. At any given point on the ocean, there are normally two high tides and two low tides each day. The common names of the two high tides are the "high high" tide and the "low high" tide; the two low tides are called the "high low" tide and the "low low" tide. On average, high tides occur 12 hours 24 minutes apart. The 12 hours is due to the Earth's rotation, and the 24 minutes to the Moon's orbit. The 12 hours is half of a solar day and the 24 minutes is half of a lunar extension, which is 1/ (29-day lunar cycle). The lunar cycle is what is tracked by tide clocks.\n\nThe time between high tide and low tide, when the water level is falling, is called the "ebb". The time between low tide and high tide, when the tide is rising, is called "flow" or "flood". At the times of high tide and low tide, the tide is said to be "turning".\n\n \nThe height of the high and low tides (relative to mean sea level) also varies. Around new and full Moon when the Sun, Moon and Earth form a line, the tidal forces due to the Sun reinforce those of the Moon, due to the syzygy found at those times.\n\nThe tides' range is then at its maximum: this is called the "spring tide", or just "springs" and is derived not from the season of spring but rather from the German verb springen, meaning "to leap up". When the Moon is at first quarter or third quarter, the sun and moon are at 90° to each other and the forces due to the Sun partially cancel out those of the Moon. At these points in the Lunar cycle, the tide's range is at its minimum: this is called the "neap tide", or "neaps".\n\nSpring tides result in high waters that are higher than average, low waters that are lower than average, slack water time that is shorter than average and stronger tidal currents than average. Neaps result in less extreme tidal conditions. Normally there is a seven day interval between springs and neaps.\n\nThe relative distance of the Moon from the Earth also affects tide heights: When the Moon is at perigee the range increases, and when it is at apogee the range is reduced. Every 7½ lunations, perigee and (alternately) either a new or full Moon coincide; at these times the range of tide heights is greatest of all, and if a storm happens to be moving onshore at this time, the consequences (in the form of property damage, etc.) can be especially severe (surfers are aware of this, and will often intentionally go out to sea during these times, as the waves are more spectacular than ever). The effect is enhanced even further if the line-up of the Sun, Earth and Moon is so exact that a solar or lunar eclipse occurs concomitant with perigee.

Just the water evaporates leaving behind the salt.  Some places along the Mediterranean they have a process that the salt water goes though leaving behind the salt that we use.  They have several locks that the salt water drain from and finally ends up as a pile of salt to be processed.\nOh by the way clouds don't melt.  The water vapors get heavy until they're so heavy the the water drop as rain droplets.No they do not mix into a different form of water.\nNO! NO! NO! to all the rest of your question.\nChuck

floods occur when the ground can't hold any more rain and the rivers and lakes crest over over their banks, this normally happens during the very heavy rain seasons that occur in most places where there is no place for the water to go like after severe thunderstorms, monsoons, hurricanes and typhones the waters receed once the rains stop and sun comes out to help with evaporation however the recession of the waters takes days and weeks to do on it's own so people normall end up pumping the water out of their homes also occurs when poorly built dams fail to hold the water in.

evaporation is when the liquid form of water eevaporates or becomes water vapor. evaporation is one part of the water cycle and is a very large one. evaporation puts water into the air as a gas called water vapor. this then condenses into tiny droplets, forming clouds. \n\nhope this helps

Now if you'd asked about delta O18 (a heavy isotope of oxygen) I could have told you how the water cycle concentrates water composed of hydrogen and heavy oxygen atoms and how this is used to study paleoclimates using ice cores and sea shells. Have a good day.

It would make water (H2O).

The water supply was at a higher elevation than the fountain, which created pressure. It's the same principle as community water towers of today.

Trees do NOT get water to their leaves using cappilary action alone. Cappilary action could lift water to maybe 10 metres maximum. The tallest trees are over 8 times that height. Cappilary action plays only a small, albeit vital, role in lifting water in trees.\n\nThe simple answer is that the tree uses the equivalent of a siphon effect to lift the water. A siphon works because water is cohesive, IOW water sticks to water. That cohesiveness of water in a siphon tube means that as water at one end falls it is able to suck more water up from the other end. Provided that the fall is greater than the rise you are trying to overcome you can use a siphon to lift water to significant heights.\n\nA tree trunk is basically composed of masses of siphon tubes filled with water, but it doesn't have any physical 'fall' component. Instead what the tree uses is the force generated by evaporation. As water enters a leaf it is exposed to the air and allowed to evaporate. Because water is cohesive that loss of water creates a negative pressure that pulls more water into the leaf within the leaf, and that in turn creates a negative pressure that pulls water into the vessel elements of the branch and the trunk. That pressure is sufficiently high to lift water to the tops of the tallest trees.\n\nWhich is why trees use such massive quantities of water. Even a small tree will use over 100 litres of water a day and less than 1% of that will be used physiologically. The rest is simply evaporated off to draw more water up the stem. It's an incredibly wasteful process.\n\nThis is also the reason why trees in dry environments are invariably shorter than plants in wetter environments. Because the system functions like a siphon the water column in the trunk can never be allowed to break or the pressure inside will immediately drop to zero. It's like getting vapour lock in a fuel line and plants can't re-prime the line. There has to always be sufficient water in the ground to feed the negative pressure required in the column. The taller the tree the greater pressure required and hence the more water required. As a result the maximum height of tree is determined in large part by the amount of water available.

The molecules in the water are in motion and as the move some of them move into the air and this is called evaporation.  The water will evaporate into the air until the air is as it can be at whatever the temperature is.  When the saturation is greater than the air can hold, condensation forms.
