Read Psalms 104:5-9  These verses that tell the story of the hydrological cycle.  That is a big word!  But it is really a simple idea:  God causes water in the ocean to evaporate up into the air as clouds.  When your mother makes tea, she puts a pot of water on the stove to boil.  When the water gets hot and begins to boil, you can see the water vapor rising up from the pot.  That is called evaporation.  Winds pick up the evaporated water from over the oceans and blows it over the land.  The evaporated water is called clouds.  When the clouds get over the land they rain and the water nourishes the land which helps our crops to grow.  The extra water then runs off the land into creeks, and then rivers, and then finally back into the ocean once again.  That is called the hydrological cycle. It is amazing that God knew all about this many many years before scientists figured it out!  God is much wiser than the scientists!  He makes it rain so that the crops will grow so that we can have food to eat.  What is your favorite food?  I like green peas.
