Why don't raindrops crash into to buildings when they fall to earth?

terminal velocity. After a while the increase in acceleration is zero. The less momentum of an object the less time it will be too acheive thie velocity. Rain drops are not very massive therefore reach this stable velocity very quikly.\n\nYou are talking the impact of raibsrops being so minimal right? By using the diction "crashed" i am assuming you mean crash through, or create damage via impact.

Raindrops: slightly bigger ones do hurt. The lower the cloud cover the more likely they could hurt.\n\nMy understanding is that the when the raindrops speed increases too much it splits up further. Thus the size goes on reducing and the pressure when it lands is reduced.\n\nComing back to the penny. The penny is solid and all force is transmitted directly.

There is a speed at which a falling object can't fall any faster, because the wind resistance holds it back.  It's called "terminal velocity".  It's different for a rock and a wad of paper the same size.  The terminal velocity for a raindrop is pretty low.

by the effect of wind.\n      the rain comes from too height & there the speed of air is very fast 'n' due to it the angle deflected.this deflected angle is very short but the height is too large so it seems like a big deflection.

They stay in the sky because they are part of our atmosphere. \n\nDefinition of a cloud - A visible body of very fine water droplets or ice particles suspended in the atmosphere at altitudes ranging up to several miles above sea level. \n\nThey aren't forced to drop to the ground unless they become larger droplets or bigger ice particles forcing them down by gravity - which is what would be rain or a storm.

Galileo postulated  the "feather drop" which states that when a feather and a stone are dropped from the same height, both objects will hit the ground at the same time.  \n\nWe see that the feather and a stone fall at different rates when dropped from a certain height because there is air resistance.  The feather will be affected by the air when falling and reaching terminal velocity before the stone will.  Therefore, the feather will fall more slowly than the stone.  \n\nHowever, if somehow we were to remove the air and then drop the feather and the stone, both the feather and the stone will fall and hit the ground at exactly the same time.  Since gravity will cause the same acceleration in both objects (feather and the stone) of 9.80 m/s^2 downwards, both objects will accelerate uniformly at the same rate towards the ground.  Hence, both objects will hit the ground at the same time, as long as we are able to ignore air resistance.

Don't listen to any of the other answers because as odd as it may seem the truth is \n\nIT MAKES NO DIFFERENCE WETHER YOU WALK OR RUN in the rain\nbecause The empirical evidence presented notwithstanding, it seems implausible that the number of raindrops hitting a person per unit time remains constant whether running or walking. The answer posits that running will cause you to hit more raindrops on the front per second, with which I agree, but claims that you will be hit less often on the top, with which I disagree on the following grounds: \n\nAs a horizontal piece of cardboard moves forward, drops that would have hit it go behind it and thus miss. However one would expect an equal number of raindrops that would have fallen in front of the cardboard to now hit. \n\nTherefore taking front and top into account, running should cause you to intersect more drops per second than walking, but will take less time to cover a certain distance. How these 2 effects balance out remains to be seen. \n\nMathematical models which assume raindrops falling vertically in planes with randomly distributed drops within the plane show the two effects to balance out perfectly, but the real life application? Who knows

High up in the atmosphere where rain clouds form, the temperature is freezing cold. At these aktltitudes the water can freeze. If there is turbulance a drop of water can freeze and be caught in an updraft. A layer of water can form around the frozen rain drop, freezing too. Thti small ice ball falls within the cloud and gets caught up in another up draft. If this continues a piece of hail is produced. It becomes too heavy to stay up and falls to the ground.\n\nIn still air the water is  in vapor form and as the temperature falls below freezing point, molecules of water coalesse and form crystals. If the air is freezing cold all the way to the ground, these crystals fall as snow. If the temperature is slightly above freezing point these crystals melt and form sleet.

There is a dent, although it is quite small and also short-lived. The air pressure just in front of the falling drop pushes the surface down just before the drop hits.\n\nBuh-bye now.

Well, the rocks don't float away because even though they may float very high, they still come back down, they usually don't have enough velocity to break the gravitational pull of the moon, even the shuttles are effected by gravity, but it SEEMS weightless because they're in a state of constant freefall while maintaining a certain horizontal velocity so they orbit the earth, in simpler terms, they're falling over the side of the world all the time.  Anyway, those rocks that may fly up, come back down, and they bounce, however they don't bounce as high, and eventually come to a rest, and as for anything that's not bolted down floating away, that's just stupid, because the moon has gravity, it's only 1/6th of Earth's gravity, but it's still there. (By the way, the level of stupidity in your question is aggravating me.)  The moon suits had to be weighted so when the astronaughts pushed on the ground with their feet, they didn't just blast off about a hundred meters into the sky.\n\nPS.  ANYONE who asks that sort of question sounds like an uneducated mendicant.\n\nPPS. If yer curious about my age, I'm 17

Actually, no one has quite gotten into the reality.  Rain is almost all rain.  But something like 99% of all precipation drops form around something called condensation nuclei.  Basically that's a fancy term to say some small particle in the air.\nThis can be dust, clay, sea salt, pollutants (leading to smog, acid rain, etc), even tiny insects... whatever's available.  Water actually takes advantage of the particle's curvature, allowing water to condense even though the air isn't 100% saturated.\nCloud seeding is an attempt to induce additional rainfall by adding more particles.  It is only marginally useful in most places.\n\nThere are also small amounts of mixed in gases (nitrogen and oxygen mainly) and any other pollutants the raindrop comes into contact with while falling through the atmosphere.\n\nBut mainly rain is just water.  Awesome stuff, too!\n\nHope I helped,\nGod bless,\nShane

If you study the details of lightening, u will find that there are some strikes that are between the clouds. Some hit the earth. There is some detailed mechnisms described in books. There u will find terms like pilot leader, streamers, etc.\n\nWhen the lightning occurs, the air gets ionised. So, even if u capture a  Lightening in your tower, the air will become an ionised conductor, so the charge will go to thwe ground. \n\nThe strike from ground occurs as well as the strike from the cloud. \n\nAbove all it is not feasible.\n\nThank you.

Depends if u are asking regarding rain hazard (outward) collapse,\nor packing/storage  (inward) collapse...

Clouds aren't just random droplets of water. What they are is tiny droplets of water that have condensed from water vapor in areas where the conditions (temperature, air pressure and humidity) are exactly right. Anywhere where you have the correct combination of these conditions, you'll get a cloud. Anywhere that you don't, you don't.\n\nAreas with this kind of conditions don't occur in random tiny places. Instead, there will be a large area of one condition that gradually shifts into another. (If this doesn't make sense, think of just temperature. You don't get a different temperature at every spot on the globe. Instead, you get a large area of warm air that gradually shifts into a large area of cooler air. The same is true for air pressure and humidity.) This is why you get a large area of 'cloud' in one place and nothing at all in another. You can think of clouds as being physical maps of the weather conditions in the sky.\n\nThis is also what holds the clouds up. In general, if a cloud is high up in the sky, the conditions just below it aren't right for the cloud to form. As the water droplets fall, they reach areas with the wrong temperature or pressure and evaporate again. Only if the clouds become densely packed enough for the water to form large enough droplets can the droplets fall to the ground. Not all clouds form high up, either... sometimes the right conditions can occur at groundlevel, giving us fog.

Great question.\n\nThe reason that they don't collide is that the moon is moving to fast.\n\nCheck this out- when the space shuttle is up in space it is only about a 100-150 miles up there. Why doesn't it just fall out of the sky and crash into the planet? \n\nWell the answer to why things don't fall out the sky is because they are in orbit- duh-. The space shuttle is not only up in space it is also moving sideways at a tremedous speed. The shuttle IS falling out of the sky, but the reason it doesn't ever hit the ground is all that sideways motion. Everytime it starts falling, the earth has moved out of the way ( sideways- remember) so it changes direction and starts to fall again, well guess what the earth has moved out of the way again. This keeps repeating and repeating. in essence anything in orbit- satelites, moons, and space shuttles are always falling but they never seem to get there. That is why the moon never hits the earth. It's important to remember that just because you are in space does not mean gravity is not pullin you down. I assure you if the shuttle was somehow able to suddenly stop it would fall out the sky like a rock. The reason the people in the space shuttle are floating is because they are falling and not because they are in space.\n\nI just have to add a little more to this statement- You know that in freefall ( you jumped out of a airplane ) you can't feel gravity and there is no up or down or sideways. The same thing with being in orbit since you are always falling you can't feel gravity either. One other thing the people that wrote first on this question really need to double check their facts. The Perfect distance and gravity cancelling out stuff is wrong. The moon could and used to be much closer to earth. It also went around earth much faster, but because of tidal action the moon has slowed down and gone into a farther out orbit. The moon even today is leaving the earth at about three inches a year. It is slowing down and so is our day- our day is getting longer because of the moon

No.\n\nSleet is frozen droplets of water (usually used to mean soft snow like pellets in Europe and hard ice pellets in the US). These typically bounce when they hit the ground.\n\nFreezing rain is supercooled droplets of liquid water. These freeze on contact with the ground (or anything else indeed). For this reason, freezing rain can be far more treacherous because it leads to very slippery conditions, and if it forms ice on structures such as power cables or trees the weight can cause them to fail.

How high up is the cloud? What is the level of the ground?\n\nIt'll take less time for a raindrop to hit the top of a mountain than to hit the ocean.
