Evaporation


Water, water, water’s everywhere and sometimes there’s none to drink.  I learned a long time ago that clouds are formed through the evaporation cycle but one of the books I read had a fancy name for it.  Convection.  Ohh, impressive.

Water vapor is everywhere.  The sun warms the earth.  This creates pockets of warm moist air that rises, as it does the water vapor cools and creates the cloud.  Then the vapors get together to form droplets.  When the droplets get big enough – heavy enough – they fall toward the ground.  Rain.

Sometimes the drops freeze, becoming snow, hail or sleet.  Sometimes it doesn’t make it to the ground.  This is another fancy name, verga.

Rain collects in lakes and rivers and puddles.  Then the sun warms the earth, and the cycle continues.  Evaporation.  Cool, huh.

Nature always points me to the Master Creator.  I never would have thought of such an elegant system for recycling water on the planet.  Would you?

Pack out what you pack in.
