Plate tectonics, mountain building, and the Flood

Please Explain:
[1] - The origin & evolution of the ocean floor in your scenario.
[2] - What caused the ocean floor to uplift in the way that they did (mid-ocean ridges) and then subside.
[3] - The origin of the continents.--Bump------------------

"So, are you starting with a cloud of pure hydrogen right out of the BB or not?"
--I am at a loss as to where his reasoning comes from to support his premise of a 'pure hydrogen' interstellar cloud being anywhere (especially proceeding a Big Bang event).-------------------

"I accept that there is a great deal of kinetic energy to be converted
to heat. As I explained before, this heat can be dissipated in many different ways including the fragmentation of solid material and melting of this to form metamorphic rocks. Plenty of evidence of this everywhere-no need to do a calculation starting from uncertain assumptions as to size density and initial temperatures etc of the affected zones. "
--The impact of the projectile sends shock waves traveling into both bodies. By the time that the shock waves have reached the back surface of the projectile the energy of the system is in four forms:[1] - kinetic energy of the projectile which is still moving;
[2] - internal energy of the projectile mostly in the form of shock compression;
[3] - kinetic energy of the target material; and
[4] - internal energy of target material, again mostly as shock compression.--When the shock wave has reached the end of the projectile a rarefaction wave travels backwards restoring some kinetic energy but also producing heat. Material is ejected, initially at low angles to the surface of the target but at speeds up to three times that of the projectile. Material ejected at a later time is a greater angles to the surface but travels more slowly. The final destination of the energy originally in the projectile is approximately--heat 31%, ejected material 49% and crushing(producing surface energy) 19% with the small residue going into spallation.--It is not at all certain how to extrapolate these results into the regime of a planetary collision in which there are many additional features:[1] - For bodies of comparable size there is no distinction between projectile and target.
[2] - The impact velocities and hence the shock compressions will be much higher than in any laboratory experiment.
[3] - The ejecta may be massive and their dispersion greatly influenced by gravitational forces.
[4] - Gravitational energy will be important for planetary bodies, especially in influencing their approach speeds.[Woolfson, 2000 - The origin and evolution of the solar system]-------------------

"I have covered all the questions you ask in my book.
It probably wont interest you anyway because I get the feeling that you would rather stick with the theories for all these points that you have learnt from others. Thats fine by me. But the offer of a free copy of my book is still open if you really want to know what I believe about the things you ask. "
--If you will seriously send me a free copy, I wouldn't mind having it. You may send it to my address:Chris Grose

Riverview, Fl. 33569I hope to find much to chew on in your book.

"It will in the post by air mail on Monday. "
--Many thanks.------------------

"Randy has given a kinetic energy number you agreed with - 8 x 10^29 joules - which must be dissipated for your planetesimal to form continents. That's about 2 x 10^29 calories. Let's assume half of that can somehow be dissipated in mechanical breaking of rocks, etc.The earth's crust weighs about 1.4 x 10^26 grams, of rock with a specific heat around .2 - let's assume .25. (Mass of oceans an atmosphere are negligible alongside this.) A starting physics calculation will show that your impact will heat the entire crust by about 2850 degrees C = 5100 degrees F, ignoring phase changes.It ain't gonna work."
--Hence, his global magma ocean. The mass of the plametisimal is likely to chemically fractionate all of its contents into the proto-earth before having it concentrate it as lithospheric continents.------------------
