Why is the sea blue and white on sunny days and turbid and yellow on cloudy days?

? We have all seen photos of the earth taken from space. We can see that this is a blue planet, especially beautiful white clouds. Because the ocean is blue, the earth seen in space is also blue, so why is the ocean blue?

? The reason of light is that light on the earth is the source of energy on the earth. It is the energy produced by the fusion of the sun, which is transmitted to the earth through light. This is a kind of energy and the source of all things on earth. Light cannot see color, but it has color. Rainbow is the color that refracts sunlight. We saw it. Red, orange, yellow, green, blue and purple are the colors of light. Prisms study the color of light. So the sun is blue.

? When the weather is clear, you will see blue sea and blue sky. Sunlight shines on the sea, soft and bright, with light waves and microwaves. The blue sea is boundless, white clouds are floating in the sky, seagulls fly happily, fishing boats return with the joy of harvest, and farms float on the coast. This is a beautiful and charming ocean.

? On cloudy or rainy days, there will be northeast wind or east wind on the sea. Except for the wind direction in thunderstorm season. At this time, the sea surface will gradually set off waves, and the undulating sea surface will push the submarine to undercurrent and swell. By then, seabed sediments and microorganisms will be discovered. In addition, if there is no bright sunshine on cloudy days, the sea water will become turbid.

? The weather at sea will change with the weather. Especially when it rains heavily, the sea water will produce waves, especially the sand in shallow water will turn into turbid waves. In deep water and reef areas, due to the lack of sediments, waves are generally blue and white.

? But on the muddy beach, where there are big waves and cloudy days, especially where rivers and sewage enter Haikou, it will be a dark and muddy sea, which is very ugly and loses its aesthetic feeling at once. The sea is like this. According to the intensity of light, the depth of seawater, algae and microorganisms, seawater will have different colors!
