where does wind come from if there are no clouds?

We have air around us. The atmosphere has high preasure and low preasure. When the high preasure area turns into low preasure, the air moves from high preasure area towards the low preasure. This movement of air from one area to another causes the wind. \n\nIt has nothing to do with clouds. The faster the low preasure area is formed, depends on whether you have clouds, or thunderstorms. Low preasure areas causes rain. This is why normally you have winds before the rain.

Both. The rotation of the earth causes storms (and your the water in your toilet) to spin in one direction depending on what hemisphere of the earth you live on.  Wind can also make clouds if blown up a mountain face by forcing warmer air into colder mountain air and thus creating clouds. These clouds form on the windward side of the mountain, and are pushed over the top of the mountain (by the wind) and then disappear on the leeward side of the mountain when the cooler air reaches the lower elevation warmer air.

Wind will never stop blowing because it is a result of differences in temperature.   If it's hot in one area and cold in the next, the air in between the two areas will rush and swirl around each other... and thus you get wind.  \n\nThank you.

Wind is just moving air which id technically a mixture of particles and gaseous molecules. The earth's rotational spin and pressure systems causes movement. These mixture is microscopic yet you feel the effect of the movement as the friction caused when brushing on your body and hence wind. You cannot see wind with the naked eye but a lot of different particles are found within the atmospheric composition.

There is the factor of where the wind originated from and the rotation of the earth.  Think about it, how fast is the north pole spinning (pretty slow, it takes 24 hrs for the earth to revolve)?  At the equator, the ground spins at a very high speed, being as the ground is further from the axis of rotation.  \n\nAs an example, a high-altitude air-mass originates from near the equator and travels away from the equator. The ground is spinning slower as you move away from the equator, but the air-mass does not lose a lot of the speed it had when it was at the equator.  Thus it will be moving relative to the ground it is now above. Since the earth rotates in the eastern direction, the wind will travel from east to west (relative to the ground it is now above).  \n\nIf the wind came from a location away from the equator and moved towards the equator, it is moving slowly relative to the equator so it will appear to be travelling slower than the rotation of the ground below it.  As a result, it would move from east to west relative to the ground.\n\nThis is how phenomenon like that jet-stream work.  This effect is called the coriolis (if I spelled it right) effect.

well if the wind is not blowing then you will have high pressure and rising until the weather is about to change. not sure about the other stuff you typed under your major question.

The moon's gravitational pull causes the waves to form.\n\nAnd those waves are what cause wind to be generated.

Gravity is pulling down on the object, air is resisting it (pushing up, if you will) and causing friction, and if there's any wind it's pushing sideways on the object. I doubt you'd have wind in your problem, though. Wind is complicated :)

Clouds are made up of water vapour which rise into the air by the heat of the sun. They stay at a height where the sun has just enough effect to keep them up.

Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on the atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect).\n\nGiven a difference in barometric pressure between two air masses, a wind will arise between the two which tends to flow from the area of high pressure to the area of low pressure until the two air masses are at the same pressure, although these flows will be modified by the Coriolis effect in the extratropics.\n\nWinds can be classified either by their scale, the kinds of forces which cause them (according to the atmospheric equations of motion), or the geographic regions in which they exist. There are global winds, such as the wind belts which exist between the atmospheric circulation cells. There are upper-level winds, such as the jet streams. There are synoptic-scale winds that result from pressure differences in surface air masses in the middle latitudes, and there are winds that come about as a consequence of geographic features such as the sea breeze. Mesoscale winds are those which act on a local scale, such as gust fronts. At the smallest scale are the microscale winds which blow on a scale of only tens to hundreds of metres and are essentially unpredictable, such as dust devils and microbursts.\n\nYou could get more information from the link below...

probably gravity. it's the most likely. without gravity there would be no wind, running water or sea waves. think about it for a second it'll make sense

Heat from the sun that warms water in the Oceans, rivers,and lakes. The water evaporates goes up inot the clouds, evaporated watre dropplets cling to dust particles in the atmoshpere, These become clouds, and as soon as enough water is clinging to one drop it beginn, rivers to rain, as if the clouds are to heavy to hold anymore. If it is cold then it will snow. This falls to the ground and (if snow melts) runs into the ocean rivers and lakes. REpeat Process with heat from the sun. ^^

Wind is the movement of air in response to formation of low pressure cells.\n\nAs someone else stated earlier, the uneven heating of the earth is the primary source for the formation of wind.\n\nCertain parts of the world gets more sunlight than others. This creates uneven heating.\n\nAreas that accumulate more heat are associated w/ low pressure cells. Warm air is less dense than cooler air & will rise.\n\nLike everything else in nature, air pressure tends to want to balance out. That means high pressure will move toward low pressure. This is the beginning of wind.\n\nThe process above describes the global movement of wind that is associated w/ pressure belts around the globe. These are called global winds (ie trade winds, easterlies, etc.)\n\nLocal winds such as valley & mountain breezes as well as sea & land breezes are created in the same way except on a much smaller scale.\n\nLocal winds begin w/ uneven heating of earth's surfaces and/or waters.\n\nFor instance, w/ a sea breeze, localized low pressure will form over land during the day since land heats up faster & to much higher temps than water.\n\nAs the air rises, cooler denser air from over the ocean moves toward the land to replace the air that has risen. This creates a convection current in which the air will circulate, creating a constant breeze.\n\nHowever, at night, the opposite is true. Low pressure forms over the water. Since water cools off more slowly than land surfaces, the water will be the source of the low pressure & the reverse will take place.

They end up becoming the 'seeds' of clouds.  That is, water in the air condenses around them, & once the process starts, those condensation  trails sometimes form into clouds up to 500 miles long.\n\nI read about it in, I believe, Popular Science a couple years ago.  There was also a fascinating article about a study that took place during the 3 days in 9/01 when all planes in the U.S. were grounded:  due apparently to the reduced cloud cover, temps everywhere were a couple degrees higher those days!

because hot air rises and cold air sinks.\n\nit creates pressure changes, which make air particles move rapidly, hence we have wind.

Clouds are made of water vapor.  You inhale clouds every time you walk into a patch of fog, because fog is just a cloud at ground level.  Clouds are formed when water evaporates from the surface of the Earth and makes its way upward.  The water condenses and we get a cloud.  When clouds get too laden with water, it falls in liquid form and we get rain.
