Why is the ocean blue?

answers:
busterwasmycat say: water is a blue substance. It is a fairly transparent substance, so you need a lot before the true blue color is obvious. Other stuff in the water (solids like clay, algae, bacteria) can dominate the color pretty easily and make it gray or green or red. But pure water is a blue thing. Absorbs red-end color. This is why it is a good greenhouse gas (heat is in the infrared and water absorbs it, and this is also how a microwave heats food, by the energy being absorbed by water). Just the way it is. Water is blue when pure. Just might need a lot before you can tell.
