So exactly how much water is on the earth?

Glad you asked!

  • Believe it or not, 70% of the earth is covered with water!
  • Even though you can’t see it, there is a lot of water underground called groundwater that soaks into the ground from rain, snow, sleet, and hail


  • There’s also a lot of land on the earth that’s just really wet, called wetlands
  • We call these areas swamps, bogs, and marshes


  • The rest is salt water or contained in the ice caps
  • All of this water, just like the water in the ocean, will make its way into the never-ending, amazing water cycle
