Water is a freak of nature, a cosmic enigma. The normal physics of matter goes like this: dense solid, less dense liquid, least dense gas. But water is otherworldly - solid ice floats in oceans, lakes and your gin-and-tonic.
If not for this paradox, bodies of water would freeze from the bottom up in temperate and polar zones. Aquatic and marine life would suffer. The vital thermal pathways of sub-surface waters would stop. Earth would be a harsh, drastically-different place.
Spring unlocks the crystalline matrix of ice and water runs back to the sea. The sun warms the ocean, gathering mist into the clouds that water the earth.
