Water, Water!

I recently learned a few amazing facts about the colossal scale of the water cycle on planet Earth:

One cubic kilometer of water is 264 billion gallons -- a lifetime supply for 70,000 people. 
The ocean's evaporate a cubic kilometer of fresh water every 72 seconds, 1,200 cubic kilometers of fresh water a day -- which is 45,000 gallons of fresh water a day for every person on earth (two full swimming pools' worth).
Each day's evaporation joins an incredible river of 12,900 cubic kilometers of water already floating in the atmosphere. That's more water whirling through the atmosphere than sits in four of the five Great Lakes combined (Michigan, Huron, Erie and Ontario). 
And yet the Earth is a relatively dry place.  If the Earth were the size of a Honda Odyssesy minivan, all the water on the planet would fit in a single half-liter bottle. 


To God be the glory!
