As atmospheric pressure falls from 2 or 3 bars to 1, much calcium carbonate precipitates from the sea water by "degassing", forming limestone and cementing the sand and mud.These become the thick sedimentary rock layers that are full of "Paleozoic" and "Mesozoic" fossils.The flood waters only had to rise hundreds of feet above sea level to cover the hills, rather than many thousands of feet to cover the mountains we have today.

This environment ends when a long swarm of meteorites of all sizes begins striking the Moon and Earth.

The bombardment goes on for forty days, causing the vapor canopy to collapse and rain down on the Earth. Meteorites hitting the ocean raise plumes of water that Noah calls "fountains of the deep".

On land, some impacts make large craters such as Vredefort and Sudbury, and unleash the Siberian flood basalts. Noah takes some of each kind of animal living around him into the Ark.

Conventional geology is built around a uniformitarian paradigm that discards "anomalous" findings and interpretations that do not support the paradigm. Delair provide a large volume of "anomalous" material in their 1997 book "Cataclysm!

Two veteran geomorphologists, Cliff Ollier and Colin Pain, pushed back in 2000 with their book "Origin of Mountains". ", which makes a compelling case for a catastrophic event that brings down the Pleistocene world in 9,500 B. You can read long excerpts (with many unfortunate copy typos) at appreciate the remarkable fit of the geologic and fossil evidence to the Shock Dynamics theory.

They conclude, "Our compilation of mountains throughout the world shows that a major phase of uplift occurred in the Pliocene-Pleistocene." "Uplift occurred over a relatively short and distinct time. It is my experience that people often mistakenly combine evidence from two separate catastrophic events into one - a global flood.

Some earth process switched on and created mountains after a period with little or no significant uplift. Here is how I see the sequence of events from a creationist point of view: Before the Flood, a water vapor canopy covers the Earth. Earth's atmosphere is dense (2 or 3 bars at sea level).

The Flood of Noah A global flood covers the protocontinent, burying the dinosaurs.

A few people, and animals that lived near them, survive in the Ark. Flood waters do not have to rise very high to cover everything because the topography is relatively low; there are none of the mountain chains we see today.

During the Flood, massive waves of ocean water wash onto the land, depositing sediment from the continental shelf.

Each wave then retreats, but rising water brings the next wave farther inland.
