1. Why is the sea blue? Information on why the sea is blue!

2. Water is clear!!! So why is the sea blue?! Lots of people want to know this! By the way!! Make sure you watch my presentation on cats nextIf you like cats!!

3. Answer: The sea is blue because water absorbs colours in the red part of the light spectrum. Like a filter, this leaves behind colours in the blue part of the light spectrum for us to see. The sea may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water. Most of the ocean, however, is completely dark. Hardly any light penetrates deeper than 200 meters (656 feet), and no light penetrates deeper than 2,000 meters (3,280 feet ).

4. Translation: The sea looks blue for the same reason the sky looks blue: the refraction and scattering of light rays. Light scatters as it passes through air or water. Since blue light has a short wavelength, it scatters most easily. Conversely, red light has a long wavelength and scatters less easily. So, the blue rays get reflected back, and that's what we 'see' as the colour of the sky or the water surface.

5. So.... That’s why the sea is blue!! Any questions?! Just ask!!
