Question

Ok why is the water in the ocean blue but our drinking water clear?

Answer 1

The first answer is wrong.

In most parts of the world the ocean is blue primarily because it is reflecting the blue color of the sky, not because of Tyndall Effect. This can be easily demonstrated by looking at the ocean on a day with full cloud cover. It will not be blue but rather gray under those conditions. The water is blue only when most of the sky is blue.

This can be further demonstrated by putting some sea water in a glass where it will not appear blue but rather will be as clear as drinking water. In some cases it will actually be a bit brownish if there is enought stuff floating in it.

Water is clear although it does preferentially absorb red light and so it will appear clear unless you have such a large quantity that light absorbtion becomes significant underwhich conditions the reflections from the surface of the water dominate its appearence and to looks blue or grey depending upon the state of the sky.

Answer 2

this is because sea (or ocean) water has many particles in suspended and colloidal state which causes tyndall effect i.e. spreading of light thus making the colour blue....same as that of sky because sky also has suspended particles while drinking water does not have these particles.....understood...now plz can u rate my answer

Answer 3

There is another more common theory.  Blue wavelengths of light are absorbed the LEAST by deep ocean currents.  These are reflected back to us (the observer).

Water is a clear liquid.
