This month we will hear and discuss the third lecture in our six-month series on geology.  Last month we looked at Dr. Kurt Wise's overview of the geological evidences supporting a prominent role of plate tectonics in Earth history including continental drift around the globe.

Conventional slow and gradual geology has had a hard time explaining the physical causes behind these processes.

 

Geophysicist Dr. John Baumgardner  has produced physical models and simulations that very successfully explain the motions of the continents and the subduction of ocean floor rocks into the mantle predicting where cold subducting plates should be found and where hot bodies of mantle should be rising. Since then tomographic data has well confirmed these predictions.  So far, Dr. Baumgardner's model and simulations are the only successful method of explaining the physics of the continental motions, plate subduction, and mantle circulation confirmed by the measured

observations.

 

Dr. Wise explained that the catastrophic process began with a collapse of the continental margins of the Pangea continental configuration that placed all of the continents together into a single landmass. This collapse began the accelerating catastrophic processes that drove subduction of oceanic crust, circulating mantle, and redistribution of

continents all approaching a new Earth scale equilibrium in a matter of a very few months! The energy driving this catastrophic process came from the cold dense ocean floor rocks falling through the hot less dense mantle to a much lower gravitational potential deep in the mantle. The whole process would slow and eventually stop as it approached a minimum energy state and a new equilibrium with the continents

in the positions we see today. During this collapse and redistribution it is likely that the oceans would be displaced over the continents in a sequence of continental scale surges reaching complete inundation well before a new equilibrium was reached. While not perfect, Dr. Baumgardner's model and simulation does an amazing job of explaining the physical mechanisms that predict what is actually observed with astounding detailed accuracy.

The conventional geologic philosophy struggles to provide any physical mechanism that might be consistent with their slow and gradual philosophy. Even so they are reluctant to follow the physical evidence instead of their preconceived philosophy.

  Those who missed these lectures and our discussion can see a YouTube version of these lectures  here and  here.  Those desiring more detail on Dr. Baumgardner's whole mantle simulation and other work can find it here and here.

For the next few months the GHCA will bring lectures that focus on a smaller scale where we can consider the structure of the many layers of rocks.  On March 8^th GHCA will start with a brief lecture by igneous rock geologist Dr. Andrew Snelling. Dr. Snelling will explore the foundational rocks of the continents and consider how these rocks might correspond to the days of creation.
