Percipitation

                                         RAIN

      Like snow and hail, rain falls when they grow  to be to heavy to carried by the cloud. From the top of the cloud the start to fall, collecting smaller water droplets on the way down until they reach the cloud base (the bottom of the cloud). Then the rain falls. Smaller rain drops, called drizzle, comes from stratus clouds.
     Smaller raindrops are shaped like a sphere. While larger raindrops make a more spheroid shape, a sphere with a dent at the bottom. The sent is caused by the wind resistance. If they grow larger they open up like a parachute before bursting into smaller raindrops.

    

   If the temperature remains above 32 degrees, precipitation particles melts into liquid drops bigger than 0.5 mm., called "rain".
