Flood theory is a branch of real science that uses clues from the Bible and scientific evidence to come up with theories about the earth's past behavior.
Genesis 7:11 states that: "On that day all the fountains of the great deep burst forth, and the windows of the heavens were opened."Many flood scientists believe the most likely interpretation of fountains of the deep is volcanic activity that, along with the flooding, dramatically changed the face of the earth, formed all the fossils we now find, and created in a short time wonders such as the Grand Canyon. (As happened on a smaller scale at Mt. St. Helens where "A small eruption in 1992 carved a canyon over 150 feet deep in a single day!" )
I'll be the first to admit that flood theory is only it's name, a theory. Just because it uses clues from the Bible doesn't mean that anyone is certain about its claims. But everything is a theory when it comes to the ancient world and some theories fit the archeological evidence better than others. I like studying flood theory along with my kids mainly because it fascinates us. It's kind of like a hobby. But I'm not insistent upon these things.
Flood Theory and the Ice Age
The following quote from the article Where Does the Ice Age Fit? sumarizes the theory well. Here's the gist: a combination of volcanic dust and the rise in ocean temperatures would have made for an ice age:
A shroud of volcanic dust and aerosols (very small particles) would have been trapped in the stratosphere for several years following the Flood. These volcanic effluents would have then reflected some of the sunlight back to space and caused cooler summers, mainly over large landmasses of the mid and high latitudes. Volcanoes would have also been active during the Ice Age and gradually declined as the earth settled down.
Abundant evidence shows substantial Ice Age volcanism, which would have replenished the dust and aerosols in the stratosphere.7 The Greenland and Antarctic ice sheets also show abundant volcanic particles and acids in the Ice Age portion of the ice cores. An ice age also requires huge amounts of precipitation.
The Genesis account records the “fountains of the great deep” bursting forth during the Flood. Crustal movements would have released hot water from the earth’s crust along with volcanism and large underwater lava flows, which would have added heat to the ocean. Earth movement and rapid Flood currents would have then mixed the warm water, so that after the Flood the oceans would be warm from pole to pole. There would be no sea ice. A warm ocean would have had much higher evaporation than the present cool ocean surface.
Most of this evaporation would have occurred at mid and high latitudes, close to the developing ice sheets, dropping the moisture on the cold continent. This is a recipe for powerful and continuous snowstorms that can be estimated using basic meteorology.9 Therefore, to cause an ice age, rare conditions are required—warm oceans for high precipitation, and cool summers for lack of melting the snow. Only then can it accumulate into an ice sheet.
The principles of atmospheric science can also estimate areas of high oceanic evaporation, the eventual depth of the ice, and even the timing of the Ice Age. Numerical simulations of precipitation in the polar regions using conventional climate models with warm sea surface temperatures have demonstrated that ice sheets thousands of feet thick could have accumulated in less than 500 years.
One of the things I enjoy about being a stay at home mom is that there are lots of opportunities to have an active mind, if you make the effort, whether or not you're home schooling.
