what is the shape of a very large rain drop?

it is a sphere while in suspension and then the classic teardrop shape while falling.

It depends on a number of variables. One factor is the temperature difference between two air masses. The warm air will hold more water than cold air, so if a warm front hits a very cold air mass the cold air will cool the warm air and it will become oversaturated with water vapor. The more the warm air is cooled the more rain will fall. \n\nAnother factor is the way the air masses are moving. If a warm front moves over cold air slowly it will form a gradual transition with the cold air remaining near the ground and the warm air climbing gradually over it. This will produce a prolonged period of rain. If a cold front pushes under a warm air mass it may form a much steeper boundary area between the two air masses. This can produce very hard short periods of rain. \n\nHere's a little diagram:\nhttp://www.tiscali.co.uk/reference/encyclopaedia/hutchinson/m0006324.html

The shape is completely random, based on how air currents (wind and updrafts) are moving around and inside the cloud. You get so many cloud shapes over time that a few random patterns are bound to resemble something else we're familiar with, such as a heart or a dog.

rain comes from clouds. clouds are actually water vapour floating in air. when they become really condensed due to a drop in temperature then they form large drop of water which cant stay afloat and so rain happens.

The rain drops because of gravity.

they are forms of water or precipitation

It forms due to diffraction of light by the small water droplets in fog. It's formation is similar to formation of the rainbow.

the "rain" is sulfuric acid.

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.

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.

I believe it is an umbrella\n\nRuth

I did a Yahoo Search for:\nflat cloud bottom\nhttp://search.yahoo.com/search?ei=utf-8&fr=slv1-&p=flat%20cloud%20bottom\n\nand I found this page which is from a sight call "Ask A Scientist" where they answer this very question:\nhttp://www.newton.dep.anl.gov/askasci/wea00/wea00041.htm\n\nThe answers aren't great, but it seems to do with level at which water vapor begins to condense into cloud forming water droplets.  It depends on the temperature or air pressure.  The reason the bottoms of some clouds look flat is that these conditions are pretty uniform over a large area.  As you go higher up, temperature and pressure decrease and the transition point is a fairly consistent altitude for that moment in time.\n\nFor more information on clouds and cloud types:\nhttp://ww2010.atmos.uiuc.edu/(Gh)/guides/mtr/cld/cldtyp/home.rxml

Wrong.  \nFrozen rain is called frozen rain (clever,eh?).\n\nHail is formed when rain is swept upward in a thunderstorm to a freezing altitude, falls and is swept up again repeatedly until the size of the hailstone is too much for the upgoing air to support.  Enough cycles of this can result in some killer size stones.........

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.

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.

I believe that it was a tropical downpour. Very heavy rain of terror that day.
