Did you know that when you look at the earth from the universe, half of the earth is oceans?

As we all know, the earth is an indispensable garden for everyone, so far, the only people in the solar system settled feelings, many people know that the size of the earth has a lot of beautiful scenery around us, but this is only a part of the beautiful scenery, as a result, everyone from their own point of view, only look at the inside of the earth, can not see the outside of the earth, from the outside of the universe to see the earth is like this, looking at the earth inside the earth and looking at the earth outside the earth are two different kinds of beauty, Everyone knows that the earth is mainly composed of the interior and the ocean, which account for 71% of the earth, because the earth accounts for 2% of the earth, so only look at the color of the earth.

One is dark blue, the other is emerald green, the other is pale yellow, the other is milky white, where the milky white is the clouds, the dark blue is of course the sea, the emerald green and the pale yellow are the grasslands and deserts on the land, there are four seasons on the earth, each season has a different color, in the case of spring on the land, when everything recovers, in summer the clouds are very few, the color of the ocean is getting bluer and bluer, the clouds are becoming more and more scarce, in the autumn, the ground is pale yellow everywhere, the dead leaves of the building, in winter it is white, everywhere is white, Everywhere you can see the color of the clean earth, the color of the earth of the orange earth.

On April 12, 1961, Soviet cosmonaut Yuri Gagarin became the first earthling to enter space. The spaceship he was in sent him to an orbit 320 kilometers high and returned around the Earth. He has the following description of the landscape of the outer universe:

The sky is dark, but the earth is dark and looks bright. According to the Earth** taken by the spaceship and the scene that the space pilot saw with his own eyes in the universe, the Earth is indeed a dark blue star.

So, why does the universe look dark blue when the Earth looks? In terms of the size of the original earth's Shanghai and land, the earth's area is 510 million square kilometers, and the ocean accounts for 71% of the area, which is twice the total land area. Most of the people live their daily lives in the Northern Hemisphere, which covers two-thirds of the world's landmass.

But you know what? The total land area of the Northern Hemisphere map is very large, but it accounts for 40% of the map area of the Northern Hemisphere, and the other 60% is ocean. The total area of the oceans in the eastern, eastern, and western hemispheres is also larger than that of land.

This kind of data information suggests that the oceans in all locations on Earth are actors.

The average depth of the Earth's oceans is close to 4,000 meters, and the flow of stagnant water reaches 10,000 cubic meters, accounting for the total water flow of the Earth's hydrosphere. Unlike the land, the ocean is a continuous whole, connected to the oceans of the present, giving rise to a unified ocean of the world, and the land is like a ship floating on the sea. As the ocean is vast and continuous, the water turns gray, and looking at the Earth in the universe, it turns into a beautiful dark blue star.

What do you think? Did you know?

Yes, most of it is oceans, because our planet is a blue planet, and in addition to blue there is also green, yellow.

Yes, because most of the area above the earth is still oceans, and as you can see from the universe, most of the earth is blue, which represents the oceans.

Yes, there are 5 oceans on the earth, and these 5 oceans occupy a large area.

I know, after all, the earth's oceans account for 70% of the area, so when the universe looks at the earth, half of it is oceans.

We know that 70% of the earth is water, and in the early days our continent was actually only one piece, but it was later separated by plate movements.

on Earth.

Where does the water come from? Is it inherent in the human mind? No. Is it produced by human practice? Neither is it. The water on earth falls from the sky.

Regarding the ** of water on the earth, scientists previously believed that the ** of water is the interior of the earth, which was naturally produced when the earth was formed. This type of theory is riddled with holes, overstretched, and difficulties, and has hardly been taken seriously these days. American scientists recently came up with a remarkable new theory:

Water on Earth comes from comets made up of ice in space.

This theory is looking outward in the right direction, but when it comes down to ice comets, it will create many problems, such as the inability to explain why the nine planets are the only ones that become the "magnets" of massive ice comets

The Earth's water is indeed placed on the Earth by some force, and the atmosphere holds this water to the Earth through the atmospheric water cycle. If there was only water and no atmosphere, even if there was a large amount of water, it would have been scattered in space long ago.

It's an extremely ingenious design.

The Earth's hydrosphere may not have had as much water at first, and the oceans were not as large as they are now. At that time, the land should have been widely exposed and connected. Later, when the outer hydrosphere of the earth ruptures, 2-3 times more water should be added to the hydrosphere of the earth, and the sea water will be flooded.

Without land, Pangea was divided into continents, forming the current pattern of the earth's surface.

The deepest Jana Trench in Mali is less than 11 kilometres deep and occupies only 1,600 kilometres of the Earth's radius compared to the Earth's radius of more than 6,000 kilometres. Since the 60s of the 20th century, with the improvement of marine development and deep-sea survey technology, people have learned more and more about deep-sea organisms.

Proportional to the radius of the Earth, and even much smaller than the ** thickness of a football surface stretched, marine life, including microorganisms, invertebrates and fish, live in water depths of more than 1,000 meters.

With the development of science and technology, human beings can go to heaven and earth, spend nine days on the moon, and go down to the five oceans to catch turtles. Scientific submersibles can dive to 10,000 meters, the deepest known to man.

The ocean gave birth to the earliest life on the earth, regulated the earth's climate, and brought abundant seafood resources to mankind.

The average depth of the ocean varies from a few meters to two or three thousand meters, and the average depth of the ocean is about 3,795 meters.

The proximity of the sea to the continent is influenced by the continent, the river, the climate, the seasons.

The temperature, salinity, color, and transparency of seawater are all affected by the land, and there are obvious changes.

Of the five oceans on Earth, the Pacific Ocean is not only the largest, but also the deepest, with an average depth of 3,970 meters.

The ocean is the central part of the ocean, the main body of the ocean. The total area of the world's oceans accounts for about 89% of the total area of the oceans.

In our continuous exploration, it was found that a very white fish can be found at a depth of 8 kilometers, but so far humans have not named this fish.

Probably because it is dark at a depth of 8 km, most of the fish are transparent.

Secondly, at a depth of more than 10,000 meters, humans have discovered the giant amoeba, although it is a single-celled organism, but it is also a great discovery.

The sea is particularly deep, at its deepest point of more than 11,000 meters, making it the deepest point on Earth.

The average depth of the ocean is 3,680 meters, and the deepest part of the ocean is in the Mariana Trench.

The deepest known ocean is the Fichaz Abyss, which has a depth of -11,034 meters.

The Earth began with a large ball of water. There is no oxygen and the temperature is extremely low.

There are very few single-celled plants and animals.

Later, when the sun shines directly, the water vapor evaporates, forming the atmosphere. Plants and animals with more complex structures have emerged.

In the beginning, the earth was just a mass of scattered matter with different chemical compositions in the universe, and later these substances were disturbed in one direction due to the action of force. And the endless interaction constitutes the most primitive earth, a lifeless earth.

Some netizens asked: Looking at the earth from space, the earth is spherical, so why won't the sea water at the bottom fall?

Newton proposed the law of gravitation in 1687, 332 years ago. The simple meaning of the law of gravitation is that any two objects in nature are attracted to each other, and this attraction is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance.

Therefore, whether it is as small as a sesame seed, a watermelon, a mountain range, or a planet, there is a gravitational force, but the gravitational force is different.

The same is true of the earth and the sea, according to the law of gravitation, they are attracted to each other, so what you think of as the bottom of the sea will not fall.

Let's look at the problem from another angle, what do you think of as "falling", do you want it to fall to the **?

In our daily experience, we think of "up and down" as the earth and the sky as the sky, but if we physically say it, what does "down" mean? It refers to the direction of the center of the earth, because the direction of gravity refers to the center of the earth. And in space, from the perspective of space, there is no "up and down".

Astronauts are not up or down in the ISS, no matter which direction their heads are facing, there is no difference, and why? Why is there no distinction between the top and the bottom? This is because of weightlessness, astronauts are weightless in the ISS because the space station orbits the earth at a speed close to kilometers per second, and the gravitational force g = centripetal acceleration experienced at this time, in other words, the gravity of the earth is equal to the centrifugal force, and it is weightless at this time, so it feels that there is no difference between up and down.

What you think of as "falling", in fact, the direction of falling should be the direction of the center of the earth, in short, the so-called "down" is actually the direction of gravity, for example, the whole earth is not "down" direction, yes, it is the surface of the sun. If the Earth's revolution suddenly brakes, then the Earth will fall to the surface of the Sun.

In addition, from the perspective of general relativity, gravity is the result of the bending of space-time by the mass of an object, and the gravitational potential well caused by the Earth's mass in the background of space-time makes any object on the earth's surface firmly "adsorbed" on the surface.

What do you think?

Liberal Arts Dockyard.

This is due to the rotation of the Earth. Although the Earth is a sphere, it has the gravitational pull of the Earth, so it can still be attached to it and will not fall.

This is because the earth has gravity, so water can be fixed to the earth like humans. Then no matter how you turn it, you won't fall down, which is a particularly magical thing.

Looking at the earth from space, the earth is a ball, and the sea water will not fall, in fact, this shows that the law of gravity is affected, because the earth's gravity on the ground is the place from the center of the earth.

First of all, such a large space of the earth is attractive, the earth has a great magnetic and gravitational pull, which can attract lakes, mountains, human beings, animals, everything on the earth, this is the mysterious power of the earth.

Because the Earth has a gravitational pull, it is attractive to all objects on the Earth, and the greater the mass of this thing, the greater the attraction. Therefore, the sea water does not fall.
