How does a sailboat move upwind or into the wind?

It cannot go directly into the wind, rather it has to go back and forth at an angle to the oncoming wind, called "tacking".\n\nIf you want to go North, but the wind is blowing out of the north, you have to go northeast, then turn and go northwest, and keep going back and forth like that until you eventually get where you are going. \n\nThe keel in a sailboat makes this possible.  It allows the boat to take wind from the side and push it forward, not tip it over.  \n\nIt's easier to see using pictures.  See the ref.

The same as everywhere else.\n\nHigher wind speeds disperse pollutants.  Wind direction determines where pollutants go.

air naturally comes from high pressure fronts to low pressure fronts\n\nalso if you look at weather maps those wierd looking squiggly lines \nthe closer together they are the higher wind speed you'll have

WIND \nAir that flows in relation to the earth's surface, generally horizontally. There are four areas of wind that are measured: direction, speed, character (gusts and squalls), and shifts. Surface winds are measured by wind vanes and anemometers, while upper level winds are detected through pilot balloons, rawin, or aircraft reports. \nWhoosh! You know that wind is moving air. But what causes the air to move? It’s the uneven heating of the earth’s atmosphere. \n\nAs the sun warms the earth’s surface, the atmosphere warms too. Some parts of the earth receive direct rays from the sun all year and are always warm. Other places receive indirect rays, so the climate is colder. Warm air, which weighs less than cool air, rises. Then cool air moves in and replaces the rising warm air. This movement of air is what makes the wind blow.

Wind speed is never zero.  It seems like it somedays, but higher up it is windy. Just look at the clouds.

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.

Well lets see....I have a Pirate buddy that could answer this with ease....You have the Main sail (main),Jib (another sail),Fore:the front,Aft:rear,Top Deck,Helm:wheel or wheel house(the thing that steers)Poop deck: I don't know,The Head:bathroom,Keel: the thing that keeps you from flipping over,Hull:the main "Body" of the vessel,The Plank:to "get rid" of extra baggage,Top Side:on top,Deck:where you walk(on Top)Mast:where you hook-up the main sails,Rigging:all the ropes,.....you know,I could go all night or you could check out:\n   http://en.wikiepedia.org/wiki/Sailing_ship

The flag is not flapping in the wind.  It is moving becuase of the momentum imparted by opening the flagpole, stretching out the flag itself, and then the drilling motion used to put the flagpole in the ground.\n\nThe flag keeps on moving because there's no atmosphere to STOP it.\n\ngo see www.badastronomy.com for more truth

either or--- Its the motion in the ocean.. Not the size of the Boat.... REMEMBER THAT!

The same way it travels through air, in waves.  It just doesn't make it very far.

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.

The wind exerts more pressure on the open side of the cups than it does on the rounded side, so that no matter which direction the wind is coming from, the cups will spin.  Wind velocity is calculated by the speed of the spin -- rotations are counted and divided by the time of measurement.  It was invented in 1846 but didn't really become accurate until electrical spin counters and timers were added.

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\nWinds can also shape landforms, via a variety of eolian processes.

The more wind the higher the waves.\n\nWhen wind blows over the ocean's surface, it creates waves. Their size depends on how far, how fast and how long the wind blows. A brief, gently breeze forms patches of tiny ripples on the surface called catspaws; strong, steady winds over long distances create large waves. But even when you feel no wind at all, you may encounter large swells created by distant storms.

Like wallablack says... Whilst going in the same direction as the wind you go in a straight line....but when you go into the wind you move in a large zig zag motion side to side edging forward in small increments using the tension between the board and the wind to propel you.

"Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface."\n\nThe sun heats up the earth's surface, the hot air rises while the cool air sinks, therefore create air movement - which is called wind.
