If we count the number of times the fish opens and closes its mouth in a minute it is less than the number of times of the human breathes in and out in a minute. Since amount of oxygen present in the water is less compared with the air the acuatic animals breath faster than terrestrial animals.
I couldn't find a diagram but was able to find the terms erosion and deposition and using these terms, first there is erosion or the wearing away away of the rock in place be it pre-existing igneous, sedimentary or metamorphic rock, then transportation often to a delta or flood-plain or basin, and then deposition of sand silt and clay and then consolidation into rock and diagenesis which involves compaction and the removal of water.
