Crossword-Solution: CARBONATION 11 letters, 2 clues 🏆 scrabble score: 15

The greater amount of carbon dioxide in the air during Palaeozoic times would have favored more rapid carbonation.

Although the action of all surface waters is toward oxidation and carbonation of these metals, the carbonate development of oxidized zones is more marked when the enclosing rocks are calcareous.

Whether single or double carbonation is used, the same general methods are employed, and results are expressed by the same chemical equation.

Later, as the mountains are worn down by the many agencies of water, wind, ice, and chemical decay, although much carbon dioxide is locked up by the carbonation of the rocks, the carbon locked up in the coal is set free and increases the carbon dioxide of the air.

One consequence of erosion and weathering was presumably a diminution of the carbon dioxide in the atmosphere, for although the ice covered perhaps a tenth of the lands and interfered with carbonation to that extent, the removal of large quantities of soil by accelerated erosion on the other nine-tenths perhaps more than counterbalanced the protective effect of the ice.
