According to my observations, the most popular answer to such questions - because nature invented it that way...

Great solution - like a face in the dirt is not dropped, but it does not answer the question. Doesn't make it any clearer...

How long do you think after this baby will ask questions? Or gradually will stop, because he will quickly realize that the normal answers will not get.

Come on, let's figure it out, it's not hard!

When you look at the sea, it really does seem blue, but when you scoop up the water, you find that the water is just as colorless as in the faucet.

The sea appears blue to us because of the way it absorbs sunlight.
When a beam of light passes through the thickness of water, some of the waves it consists of are absorbed by the water (remember that visible white light is composed of different wavelengths. Waves of different lengths have different colors. )
Blue light is absorbed the least, scattered, reflected back and into our eyes.

This is why the sea looks blue.

The actual shade of blue sea depends on several factors:
- The depth of the water.
- The amount of sunlight.
- What is in the water. For example, if there is a lot of algae on the bottom, the sea may look more green.

What is the most unusual color of the sea/ocean that you have seen?
