WHY THE SKY CRIES

     Have you ever wondered what makes rain into rain?  Is it only the clouds?  Is there a huge bucket of water in the sky?  Is the sky crying? 
     Raindrops are first a collection of many droplets.  Droplets are smaller than mist.  This practically invisible mist is formed from water vapors.  Water vapors are always in the air.  With machines, these water vapors can be measured.  They're commonly known as humidity.  When humidity reaches one hundred percent, clouds begin to form.
     When the humidity is on the ground, it is referred as fog.  It looks like white, smokeless smoke.  When this is in the sky, it makes clouds.  Clouds are a mixture of water vapor, mist, dust and water droplets. 
     If the conditions are right in the atmosphere to form rain, the clouds begin to grow.  As the clouds are growing, they're also drawing in more moisture.  When the water droplets begin to form, they also increase in numbers.  This causes the water droplets to collide.  The collisions cause the droplets to form into a solid drop.  These drops are to solid to be called airborne.  When these solid drops fall from the clouds, it makes rain.
     Water is very important to our planet.  Rain gives us water to drink, grow our foods, clean ourselves, wash clothing, water is the home for our fish and sea life.  Water can also save lives.  Can you think of ways that water is useful to you?
