Now while all this was taking place, something else was being deposited into the Earth from the Cosmos. Another substance was being added to the silica; it is what you find today as the chalky constituents of the Earth.

It came to the Earth at a later stage than the silica but it too came from the Cosmos. Thus chalk is to be found as a second substance in the Earth.
