Why are the skies and oceans of the Earth blue?

This. Be.? Min Yi ?。? No..

Be.? Child.

Because 70% of the earth's surface is covered by oceans, and the burning oceans reflect blue light, the rest of the earth's sky and oceans are covered with blue. This is a natural phenomenon, not a design.

The Earth's sky and ocean are the macro of what is blue? Is this designed? Because the sea is blue! The sea blinds the blue reflection to the sky, so the sky becomes blue.

This is due to the fact that it has been received. It is due to the fact that the sunlight will have different scattering phenomena after entering the atmosphere in the field socks, and the color that is refracted on the water surface and the sky is blue. It's not by design, it's a natural choice.

1. The sea water is blue because: Sunlight is composed of seven colors: red, orange, yellow, green, cyan, blue, and violet. When sunlight hits the sea, red light and yellow light, which have long wavelengths, are easily absorbed, but some of the light with shorter wavelengths such as blue light is also absorbed by the sea and the sea.

Algae are absorbed, but most of them are reflected back by the seawater, so the sea we see is blue light reflected into our eyes, and the sea we see is blue.

2. The sky is blue because: The scattering of sunlight by the atmosphere makes the sky appear blue. The surface of the earth is surrounded by the atmosphere, when the sunlight enters the atmosphere, due to the blocking of air molecules, the sunlight will be scattered, the blue light wavelength is short, can not penetrate the atmosphere, it is reflected back, so the sky we see is blue.

1. Sunlight is the intense light radiation produced by the thermonuclear fusion reaction of the sun, and the sunlight contains various wavelengths of light: infrared, red, orange, yellow, green, blue, indigo, violet, ultraviolet, etc., the light close to the red light contains a large proportion of heat energy, and the violet light contains a small proportion of heat energy. Sunlight is an electromagnetic wave in the visible light band, when the sunlight is absorbed by the object, the light energy is converted into heat energy, and after the heat energy is absorbed by the water, the water temperature rises, which is the prerequisite for the solar water heater to be able to heat water.

Black objects absorb the most light, gray objects absorb less light, and white or specular objects absorb the least light.

2. The sunlight is decomposed into 7 colors of red, orange, yellow, green, blue, blue and purple (or red, orange, yellow, green, blue, indigo) through the prism, instead of the 3 colors of red, green and blue, indicating that the colors in nature are not completely composed of 3 colors: red, green and blue. But for ordinary people, three primary colors can express all colors. The so-called three primary colors, that is, red, green and blue, can be mixed to make people feel all the colors in nature, but it is not really obtained that these colors are not really obtained, and the real sunlight is not 7 colors, but all continuous wavelengths of light waves from infrared to ultraviolet.

It's all a natural phenomenon, and we can't tell, it's a natural occurrence.

Because of the principle of light reflection, the atmosphere refracts the rest of the light, leaving only blue light. So what we see is blue.

The main reason why the sky and oceans on Earth are blue is because of the principle of refraction of light. Because in the seawater, the refraction of light will filter out some of the other colors, and only the blue color will be displayed. So when we see the sky and the ocean, it will be blue, and the sky will be blue due to the refraction of the seawater.

The air around us is transparent. Gases in the atmosphere absorb scattered light from different angles, so the ocean and sky appear different shades of blue depending on the angle.

Each of us is the same, living under the same sky, whenever we go outside, if the weather is good, we will see a blue sky, this visual enjoyment makes people have a sense of relaxation, blue represents a symbol of eternity in our hearts, blue is the color that most people generally like,Then both the sky and the ocean are blue in nature because of the scattering and reflection of light in the air

Nowadays, there are many people who like to travel everywhere, when you arrive at the seaside, you will find that the sea is boundless, boundless, as far as the eye can see, you can't see its edge at all, there is a feeling that the sea and the sky are connected, we can all see, the ocean and the sky are the same color, that is because there is a layer of air on the surface of the earth surrounding, and the air is nothing in our naked eyes, in fact, the air also contains a lot of tiny dust, crystals and small water droplets.

In summer, we often see that the sun's rays are a beam of white light, but it is composed of red, orange, yellow, green, cyan, blue, and purple colored rays, just like the rainbow rays we usually see, which will only be seen when the sun and rainy days intersect, and the chance of seeing it is very small. Whenever sunlight is emitted in the air, the color light with a longer wavelength transmits the most power, and it can shine directly to the ground through the tiny dust in the atmosphere, but the light with a shorter wavelength is easily scattered by the tiny particles suspended in the air, so the sky appears blue.

Whenever the sun shines on the surface of the sea, the light with a longer wavelength can bypass all the obstacles in the air and shine directly on the ocean, and then gradually be absorbed by the seawater and marine life in the ocean, but although a small part of the shorter wavelength light is absorbed by the seawater, most of it will still be scattered around, so the sea we see always shows the same color as the sky, blue. This is not a visual error on our part, but a scientific basis.

Most people know that the sky is blue, and so is the sea. In fact, the color of seawater is originally pale because of the absorption, refraction and reflection of sunlight by seawater, which reflects the blue light with short wavelength. It's the same as the sky is blue.

Because the blue sky shines into the sea by the refraction of light, the color of the sea is also blue.

When the sun's white light hits the seawater, it takes on a blue color due to the absorption and scattering of the white light.

Because the sun has many colors of light that hit the sea, but the light of other colors is not obvious at all, only the blue light is more reflective, so we only see that the sea is blue, and we don't see other colors.

Because the sea does not absorb enough blue light from the sun's rays, it is the blue we see now.

There are many strange phenomena in nature, for example, on a clear day, when we look up at the sky, we find that it is blue, and it is so blue that it is clear and comfortable, which makes people feel pleasing to the eye, and science has also explained the phenomenon that the sky is blue.

The reason why the sky appears blue is because the atmosphere scatters sunlight. But the sea is blue like the sky, do you know why the sea is blue? Next, let's uncover the mystery of the blue sea, and you will know it after reading it.

The ocean has always been the focus of scientific research, and scientists have been working tirelessly on marine life and the depth of the seabed. Scientists go deep into the seabed to study, but ignore the external manifestation of the sea - the color of the sea, I believe everyone has also discussed this issue.

Why is the water in the ocean blue?

When you come to the beach, the first thing that catches your eye is the endless sea and the whole blue of the sea. The sky is blue, and so is the sea. If you are in the middle of it, you will completely linger in the beautiful scenery of "sky blue, sea blue".

Why does the water in the sea look blue overall? And when you approach and hold the sea water in the palm of your hand, is it transparent? This is due to the depth of the sea water and the color of the sea when it absorbs sunlight.

The depth of the seawater.

As for the depth of the sea, the deepest trench in the world that has been explored so far is the Mariana Trench, which is about 20,000 meters deep, but this remains a mystery. The reason why the ocean is blue is related to the depth of the water and the amount of water. The depth of the ocean is very deep, and although humans can go deep into the sea, the bottom of the sea is not as lit as on land, so the seabed that explorers see is very dark.

Studies have shown that as you get closer to the surface, the bottom of the ocean gets brighter and brighter, as if it were a bright night scene, like a black and blue sky. Therefore, the deeper the sea, the bluer the sea water will appear to people, which can also explain why the sea water held in the palm of the hand is transparent.

The color of seawater when it absorbs sunlight.

When sunlight hits the surface of the sea, the sea selectively absorbs the three primary colors of sunlight – red, yellow, and blue. Of course, seawater absorbs light waves at longer wavelengths, while red broadcast and yellow light waves have wavelengths higher than blue light wavelengths. Therefore, when the sun shines on the surface of the sea, the sea water only absorbs the light waves with long wavelengths, and retains all the blue light waves.

Therefore, the sea water is blue in the eyes of people, and if the water does not absorb red light waves, then the color of the sea water is probably not blue.
