H		H		The Evolution of the Planet Earth Rothschild and Lister
								"Liquid water is the crucial difference between Earth and the other planets. Liquid water enables the plate system to operate. Liquid water is needed to make subduction zones operate, to create granitoid intrusions, and andesite volcanoes, and to maintain the continents.      If liquid water were lost, carbon dioxide would degas, the plate system would probably be replaced by a plume-led system and the world would be a very different place, either Venus-like or, ultimately Mars-like."
