Question

Lakes, rivers, and streams make up what percent of the fresh water on Earth?

Answer 1

It is a very small amount as the oceans are so large, freshwater is really quite rare. Have a read of this site: http://www.epa.gov/agriculture/tsur.html

Answer 2

Well, freshwater makes up about three percent [3%] of the world's water. I'm not really sure how else to explain it. 97% of the world's water is salt water.
