1.Living creatures are amazing at building their homes from just about anything
2.But creatures are : , algae, and giant snails engineer their own building material, like magic, by pulling two dissolved chemicals -- calcium and carbonate -- out of the water to form solid shells of, surprise, calcium carbonate
3.The reason those shells don't dissolve back into calcium and carbonate as soon as they're built is that ocean water is already holding as much calcium and carbonate as it can, so the mineral forms much more easily than it dissolves
4.At least, that's the way it works near the surface, where the shell-builders live
5.But at greater depths, water isn't quite as saturated with calcium and carbonate, and thus calcium carbonate is easier to dissolve
