The rain drops because of gravity.

Any thing moving through the atmosphere experiences the force of gravity and a drag force due to the friction of the air as it moves through it. When the object is falling, the force of gravity is directed towards the ground and the drag force directed upwards. As the body moves faster, the drag force becomes larger and larger until it equals the force of gravity and the object then falls at a constant velocity. This velocity is called the terminal velocity. For a person jumping out of an airplane, in skydiving, it is roughly 120-150 miles per hour. The terminal velocity of a water drop is much smaller. A large raindrop (5 mm in diameter) will fall at a velocity of around 20 mph. If you get hit by a large raindrop you will definitely feel it. However its still not large enough to cause much pain. The smaller the raindrop the slower it falls and hence the less energy it has when it hits you. If you dropped a grain of sand the same size as a raindrop it wouldn't hurt either. Pebbles are much heavier than raindrops and hit your head with a lot more force. Force is directly proportional to the mass and velocity of an object.\n\nOf course hail, which is really just a bunch of frozen raindrops which have joined together, is actually less dense than water but will certainly hurt due to its large mass.

Because it is soothing and a constant sound. It is a statistic fact that most people sleep better when listening to rain sounds because they are calming and filter out other noises. So that is probably why you slept all day :)

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. ^^

This is complicated! I am not good at this but just think:\neven the angle of the rain drop is too complicated! It can be affected by the speed of the wind, the size of the droplet, the altitude (maybe?), etc., etc.\nNow if the glass is full of dirt that will hold the droplets, or the glass is coated with something slippery, then the speed will be affected, too.\nIf the air is so polluted, the rain is acid, then ... \nAnd there could be more factors....

Several possible reasons. One is that downdrafts often form at the periphery of the clouds - which may expand a bit and drag the sides down along with them. More often, water droplets which comprise the clouds are falling. When the cloud is forming, updrafts easily suspend the water droplets. After the updrafts generally cease, then water droplets fall. Because they condensed at the level of cloud base they usually evaporate there also - but not immediately.

Because it receives the largest amount of rainfall due to the fact that its near the coast. Also, being near the coast allows for the soil to be more fertile, making it more productive for farming.

Air is heated by the surface of the Earth on a Hot and sunny Day.  Hot air rises.  AS it rises it expands due to lowered atmospheric pressure.  As it expands it cools and begins to decend again.  Also if the air is moist as it cools it must release the moisture (rain -or hail if it is high and cold enough.)  This begins a circulation pattern up in the middle and down outside.  Often hail will begin to fall only to be caught in an updraft and carried aloft again.  This cycle continues until the hail is too heavy for the updrafts to lift it and it makes it to the ground.  This is why very strong thunderstoms with violent updrafts produce large hail.

When sun shines on water, it warms it up and since heat is lighter, the water kinda floats up into the air. That's called evaporating. Then when it's high in the sky, many little water droplets come together and from clouds. When there's too many water droplets, the cloud becomes to watery and it rains. Then it starts all over again.

It rained every Thursday - or at least it did somewhere in the World.\n\nPerhaps if you specified a geographical location then a local meteorologist might be able to give you the answer you're seeking.

Clouds are tiny droplets of water that have condensed on condensation nuclei such as pollen, dust, ash, & pollution in the troposphere.\n\nB/c they are very tiny and independant of each other, they tend to be suspended. This is due to various things such as updrafts, winds, etc. They are very lightweight. Only when they begin to start growing in size will gravity take over & they start to fall as rain.

Yup, it does.  If the air contains dust particles( also soot from car exhausts), rain drops will form a colloidal solution with the dust and carry it down to the ground, or in this case, your eyeglasses.  And when the rainwater evaporates, what are left are the dust particles.

The reason it doesn't rain is because the area is located under an almost permanent high pressure system.\n\nThat is because the surface air rises at the equator due to the higher temperatures. As the equatorial air rises it cools and the water condenses out and fall as rain. The cold air then falls back to the surface in those two sub-equatorial belts. The air at this stage is depleted of all moisture, and because the air is falling it creates a high pressure system that prevents rain producing weather systems from developing.\n\nThat is a fairly simplistic summary of some complex weather systems, but it suffices to explain why most of the Arabian Peninsula is desert.

Well...\n\nThe "sun is out" whenever there is a break in the clouds that can let the sunlight in.  You can still have clouds overhead providing precipitation.\n\nAlso, in rare cases, the clouds can drop precipitation and quickly leave while it is still falling to the earth, even though it is not hitting the ground yet.  Remember that precipitation takes a few minutes to travel from the clouds to the ground.\n\nPEACE IS COMMING SOON!

There are a couple of reasons that work together to explain this situation. The first one has to do with how raindrops form. \n\nNow, it may seem silly to make such an obvious statement as, "Rain always falls from clouds." But once it has been said, we can then ask, "What is going on inside those clouds?" And that question leads us to plenty of relevant information! \n\nDo you remember the last time your local weather was described as being "hot and humid"? Do you remember what it FELT like? Do you also remember what the air LOOKED like? The reason I am asking these questions is because it is important to know that ordinary water is commonly found in one of three forms: solid, liquid, or gas. The liquid form is what we call "water", while the solid form we call "ice", and the gas form we call "water vapor". Water vapor is colorless, odorless, and invisible. But you sure can FEEL it on a hot and humid day! \n\nNext, do you remember the last time you encountered some fog? Think about what IT looked like. If you looked real close, you would have seen zillions of tiny tiny droplets of water floating in the air. And, if you remember the last time you saw some steam, you might think that it looked just like fog (except it was hotter). Steam is NOT pure water vapor! \n\nWell, it happens that the description, "zillions of tiny tiny droplets of water floating in the air", applies to every fog, to every mist, to every burst of steam -- and to every cloud in the sky. If you sit back and simply watch the clouds for a while, you will see that some clouds grow, some shrink, and some do nothing but move across the sky. What is happening to the growing or shrinking clouds? When a cloud grows, water vapor in the air gradually "condenses" to form lots more tiny tiny droplets. When a cloud shrinks, many droplets are completely "evaporating" to become invisible water vapor. \n\nAs the winds move air across the sky, carrying clouds along, fragments of wind known as "eddys" can do strange things to the shapes of clouds. A common game is to study a cloud's shape and guess what it looks like. Also, winds from different directions can collide with each other, which often has great effects upon clouds. It depends on how cold or warm the colliding winds are, and how much water each wind carries (only the differences matter, not whether the water is in the form of vapor or tiny drops). \n\nFor rain to happen, the weather conditions inside the clouds, and surrounding them, has to cause the droplets to grow. Some droplets will grow by colliding and combining with each other -- just what you Asked about. Some droplets will grow by acquiring more and more water vapor from the air. Some will do both. But the important thing to remember now is that MOST of the droplets in the clouds grow at the same time! \n\nBUT, the droplets do not all grow at the same rate; some grow faster than others. As soon as ANY get big enough, they start to fall out of the cloud. Water is heavier than air, after all. Depending on the wind conditions, those first raindrops might be blown back up into the cloud, where they can grow some more. Eventually, however, they get too big to stay up in the air, so they fall all the way to the ground. And the slower-growing droplets will fall after them, and the slower-growing-yet droplets will fall after THEM, and so on. This is the essence of the raining process. \n\nAs I said at the start, there are a couple of reasons why the raindrops don't combine to make a single stream. The first reason is simply that raindrops start falling just as soon as they are too heavy to stay in the air. The second reason is that they are all falling together DOWNWARDS, not sideways. If the wind blows them sideways, they all move TOGETHER sideways. That isn't good enough to cause them to meet each other, while falling, so they could combine to form a si

The rain falls from lower altitudes where the ambient temperatures are warmer. The hail starts out as rain but high winds carry it upward to higher altitudes where it freezes due to lower temps. The hail stones fall and get wet as they pass through the warmer rain clouds, then they are swept up again to refreeze, thus growing larger in diameter. This process repeats until the hail stones get heavy enough that the upward winds cannot carry them up again. They fall to the ground. Large hail stones indicate high winds.

Since a cloud is made up of lots of small droplets of condensed water (or, in the case of some clouds, the condensed water freezes into ice crystals), if you were able to "shake" the cloud (get the water droplets moving around randomly) they would collide and form larger water drops.  These drops should then eventually become heavy enough to drop from the sky as rain.\n\nWikipedia has a pretty good article on clouds.
