Why sea appears blue in colour ? SCIENCE COLLECTOR

The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71 percent of the Earth's surface.
A sea is defined as a portion of the ocean that is partly surrounded by land.

The sea looks blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.

Water molecules scatter blue wavelengths by absorbing the light waves, and then rapidly re-emitting the light waves in different directions. That is why there are mostly blue wavelengths that are reflected back to our eyes. Sometimes oceans look green.

In water, absorption is strong in the red and weak in the blue, thus red light is absorbed quickly in the ocean leaving blue. Almost all sunlight that enters the ocean is absorbed, except very close to the coast. The red, yellow, and green wavelengths of sunlight are absorbed by water molecules in the ocean.

Why is a glass of water not blue?
It is because the glass of water is too small to absorb more red light waves.
