Condensation and Cloud Formation

1.  Heat from the sun causes water from the ocean, lakes, seas and ponds to evaporate – i.e., change its phase from a liquid to a vapor

  • The change of phase from a liquid to a vapor (or gas) is called “Evaporation”

2.  The water vapor in turn rises and, as it does, it eventually reaches a level in the atmosphere where the temperature is cool enough to change the water vapor back into a liquid

  • The change of phase from vapor to liquid is called “Condensation” – this is the process that causes steam from a hot shower to fog up a bathroom mirror

3.  Water condenses in the air in tiny droplets about 1/100 of a millimeter in diameter, so small they remain aloft as clouds

4.  Usually for rain drops to form there must also be small solid particles suspended in the air – usually ice or some other substance

  • As the water droplets collect around these particles, they growing larger and larger

5.  When they are too heavy to remain in the sky, they fall back to earth as rain or some other form of “Precipitation”

  • Once the weight of the rain drops (or hail, sleet, or snow) is too heavy for the atmosphere (and wind) to keep aloft, then it will fall back to earth as “Precipitation” 1

 

“For He draws up drops of water which distill as rain from the mist, which the clouds drop down and pour abundantly on man. Indeed, can anyone understand the spreading of clouds, the thunder from His canopy?”                                                                                          – Job 36: 27 – 29

“When He utters His voice, there is a multitude of waters in the heavens: “And He causes the vapors to ascend from the ends of the earth. He makes lightning for the rain. He brings the wind out of His treasuries”.”                                                                                                       – Jeremiah 10: 13

 

6.  Job is writing some 4,000 years ago – yet, he describes the process of making rain with profound accuracy:

  • Evaporation – “drawing up drops of water”
  • Condensation – “from the mist”
  • Precipitation – “distill as rain”

7.  The fact that Job uses the word “distill” evidences great insight into the “Water Cycle” for impurities are removed through this process

  • This is why rain water drawn from the ocean comes down as fresh water
  • The Hebrew transliteration at play here is “zaqaq” which means to strain, purify, distil and refine 2

8.  Jeremiah conveys the same idea around 2,600 years ago – but he also makes mention of lightning and wind

  • Electric discharges play an important role in rain generation
  • Wind flow changes air pressure and also plays an important role in rain generation 3

 

“He binds up water in His thick clouds, yet the clouds are not broken under it.”      – Job 26: 8

“If the clouds are full of rain, they empty themselves upon the earth.”             – Ecclesiastes 11: 3

9.  As we’ve said, within clouds the water condenses in the air in tiny droplets about 1/100 of a millimeter in diameter

  • This enables the water to remain aloft as clouds

10.  Usually for rain drops to form there must also be small solid particles suspended in the air – usually ice or some other substance

  • As the water droplets collect around these particles, they growing larger and larger

11.  When they are too heavy to remain in the sky, they fall back to earth as rain or some other form of “Precipitation”

  • Once the weight of the rain drops (or hail, sleet, or snow) is too heavy for the atmosphere (and wind) to keep aloft, then it will fall back to earth as “Precipitation”

12.  Job’s description in the text of what is taking place within clouds is dead-on accurate

  • The water is “bound up” within the “thick clouds” as it is lighter than the air around it (and holding it in place)

13.  Solomon expresses a similar idea in Ecclesiastes

14.  The Bible is accurate in its meteorology
