Why is the Ocean Blue?

The video explains why the sky and ocean appear blue, focusing on Rayleigh scattering for the sky and light absorption and reflection for the ocean. It details how water molecules absorb certain wavelengths, leaving blue to be reflected. The video also covers how ocean depth affects light absorption, why a glass of water looks clear, and factors causing ocean color variations.

What causes the sky to appear blue?

• The reflection of the ocean

• Rayleigh scattering

• Presence of blue particles in the air

• Absorption of red light

Why does the ocean appear blue?

• It reflects blue wavelengths

• It contains blue algae

• It reflects the sky's color

• It absorbs blue light

What happens to light as it penetrates deeper into the ocean?

• Blue light is absorbed more

• Only red light is absorbed

• All colors are absorbed equally

• Red light is absorbed more

Why doesn't a glass of water appear blue?

• It absorbs a tiny amount of red light

• It contains no blue particles

• It is too shallow to show color

• It reflects all colors equally

What can cause the ocean to appear bluish-green or brown?

• The depth of the ocean

• The presence of microorganisms and silt

• The time of day

• The temperature of the water
