what the desiccation of the upper mantle would have done to the Earth.
the extra heat from the added friction would have moved upwards releasing hydrogen and oxygen from the minerals
this would have been a extremely large volume of hydrogen
and oxygen and you would think that through this release the overall mass would tend to shrink resulting in the events
you propose , however with the added heat the magma itself would expand into any void created by the hydrogen and oxygen release.
it would have slowly happened over a period of time gradually
releasing the hydrogen and oxygen from the minerals that the hydrogen and oxygen were locked up in.
it would not have been a sudden event that occurred in a matter of minutes or hours.
Nor have we considered how all the water would have made its way back into the mantle minerals.
bonded pairs of ions?
Apatite naturally soaks up water as water-bearing magma cools, locking it up in the form of hydroxyl ions—pairs of bonded hydrogen and oxygen atoms.
the article says that many believe that the moon was formed
from an impactor , I hold that the moon was once part of the
earth , and that is why the moon always faces the earth with the same face.
because the moons heaviest parts moved toward the earth as the
moon cooled , also forming a hollow in the moon on the dark side.
