Hydrology is that branch of geology that studies water on the earth and in the atmosphere.

I have always loved nature and have done lots of camping and hiking in the Western USA where these activities were accessible to amateurs.  One of the things that has always fascinated me is the presence of sea fossils even on mountains.  It always brings to my mind the biblical account of the great Flood that covered all the mountains of the earth (Gen 7:19).  Now I can hear the sneers, and the wonder how any intelligent person could be so ill-informed as to believe the Flood "myth" in the Bible.  But I believe it.  Look at it this way:  If a person believes in the resurrection of Christ, then the Flood is nothing in comparison!  Unashamedly, I fully confess that I believe the Bible is the Word of God.

Now please consider the understandings of the Water Cycle as found in the OT:

Ecclesiastes 1:7 (ESV)
⁷ All streams run to the sea, but the sea is not full; to the place where the streams flow, there they flow again.

Job 36:27-28 (ESV)
²⁷ For he draws up the drops of water; they distill his mist in rain, ²⁸ which the skies pour down and drop on mankind abundantly.

Job 38:16 (ESV)
¹⁶ “Have you entered into the springs of the sea, or walked in the recesses of the deep?

Amos 5:8 (ESV)
⁸ He who made the Pleiades and Orion, and turns deep darkness into the morning and darkens the day into night, who calls for the waters of the sea and pours them out on the surface of the earth, the Lord is his name;

Amos 9:5-6 (ESV)
⁵ The Lord God of hosts, he who touches the earth and it melts, and all who dwell in it mourn, and all of it rises like the Nile, and sinks again, like the Nile of Egypt; ⁶ who builds his upper chambers in the heavens and founds his vault upon the earth; who calls for the waters of the sea and pours them out upon the surface of the earth— the Lord is his name.

Now please consider the following USGS diagram that depicts the Water Cycle.¹  (Because the following USGS figure is in PNG-25 format, no all internet browsers may be able to view it.  However, you may be able to view it at the Wikipedia article.)  Note that all elements of the diagram, including the underground water making its way to come up from the ocean floor ("springs of the sea") are all present and accounted for in the OT.


The person credited with the modern concept of the Water Cycle is Bernard Palissy in the 16th century A.D.².  However, it is clear from the OT references above that the elements of the Water Cycle were already known at least 1400 years before Christ.

Again, this appears to be another example of scientific foreknowledge in the Bible.
