An Overview of Creation Science Flood Models
Just for fun = Cell Size and Scale
That site above is worth visiting, trust me! They may not be Creationists, but they know how to make a great visual aid. You will also find that the real science involved in studying cells has NOTHING at all to do with Darwinism. Darwinism is the division of "science" that has no practical purpose and often actually hinders research (for instance, the faulty concept of vestigial organs meant lots of folks had things removed from their bodies in error).
Here is an overview of Flood models and hypotheses concerning the sedimentary rock layers. A good overview of advancing real science in which the Bible is part of the process but evidence is respected and guides changes in said hypotheses. This is the way true Creation Science works - understanding that what the Bible says will be true but also understanding that the Bible is primarily a book of history and philosophy, a message from Creator to the created, and not intended to be a science textbook. So Creation Science focuses on the evidence and, as it happens, the Creation models that speak to the fossil rock layers actually fit the evidence rather than present fairy tales that do not.
Flood models and biblical realism
Biblical creationists by definition believe in a globe-covering flood. But how this
occurred has been a matter of intense debate within the creationist geologist community.
Some general observations can be made from a theological, philosophic and scientific
perspective.

This article does reveal some ideas that were considered and cast aside, such as the water canopy hypothesis, which would also cause such an increase in atmospheric pressure that living things likely would not have been able to handle the pressure. Early Creation Science in the mid-20th Century had to catch up to where all of science had been well into the beginning of the century, because Darwinism did not actually become popularized until after World War One. Now new discoveries in science should have caused Darwinism to have been abandoned, but just as it took several decades for Darwinism to become accepted it appears that it will require several decades to be abandoned by science at large.
There is some pretty good evidence for rapidly subducted tectonic plates based on the temperature differences measured in the magma where the subducted plates would have not yet reached equilibrium with the normal temperatures. Such temperature variations have indeed been measured and are hard to explain other than by a massive rapid subduction of cold surface rock.
It is hard to comprehend the sheer size of the biggest dinosaurs found in the Flood layers if the atmosphere of the Earth was not more oxygenated before the Flood, as their structure apparently would preclude the larger ones from being able to survive on today's mixture of oxygen within the atmosphere. Physiologists have concluded the largest dinosaurs either had a more oxygenated atmosphere to breath or they had a thus far undetected means to extract more oxygen from their lungs than now-living organisms.
