Why is the Ocean Blue?

Parents - finally, the non-answer we've been giving all along is right: Nobody knows!

There are several theories as to why the ocean is usually blue. Some scientists believe that when sunlight hits seawater, part of the white light is absorbed and part is reflected. White light is composed of various shades (all the colors in the rainbow). Seawater does not absorb blue light, so the blue light is reflected outwards. Some scientists believe that suspended matter in the sea is responsible for its blue color.
Something else of interest:

Real forests grow in the oceans! Off the coast of California, Giant Kelp plants (large brown seaweed) can grow to 125 feet in length.

Cool beans.
