It has become more fashionable these days to talk in terms of geological and astronomical catastrophes. One major segment of current geological enquiry concentrates on on life-form extinctions at the geological boundaries, plus the evidence of simultaneous major earth movements. A brief overview of one model explaining these events is given below. It is based on the evidence for changing light-speed as presented in The Atomic Constants, Light and Time, Creation and Catastrophe , and a major scientific paper that is currently undergoing review.
Meteorites are the left-overs from the creation of the solar system.
Upon heating, this water is given up, and the mineral turns to olivine. Interestingly, the earth's mantle is largely composed of olivines. The following scenario therefore bears examination. This radioactive heating drove the water out of the minerals in the mantle towards the earth's surface. Through pores in the crust, this water came to the surface as springs and geysers and watered the ground.
