71 of the earth is the ocean, why not water polo?

We know that there are many animals on our planet, and these animals accompany us to grow up, and these animals are also the most perfect products designed by the world's greatest designer, the earth, and human beings are one of them. And the earth is in the universe, it is a blue planet, and 71% of the earth is ocean, so why is the earth not called water ball? There are several reasons why it is not called water polo.

1. Humans live on the land, not the sea. First of all, we humans live on land, not on the ocean. The earth has a lot to do with a human habit, if we live in the sea, then it may be called a water polo.

The name of the earth is only prescribed by human beings, and we do not swim in the sea like fish, swimming freely in the sea. We humans only deserve to live on land, so we humans live on land, and humans who live on land will call our planet the earth. <>

2. Plants on the earth also live on land. Secondly, another reason is that these animals and plants on the earth also live on land, and the number of people living on land is extremely large. Humans have many names for things in front of them.

For example, although the ocean is said to be extremely large in terms of its area and the number of flora and fauna, these humans cannot relate. For the sake of convenience, we must still use the purpose of human beings to make a unified name. <>

3. The resources used by human beings at that time came from the land. The last reason is that the resources used by human beings at that time were basically all from land, such as trees, oil, minerals, electricity, water, all of which came from land. As far as the ocean is concerned, we only catch food in the ocean, although it is relatively large, and it still occupies about 70%.

Because the earth was born without water, the water on the earth was formed by two successive heavy rainstorms.

Because in ancient times, people did not know that the main body of the earth's surface was the ocean, and then with the development of science and technology, people's understanding of the earth became clearer, but because this name has been called habitual, so the name was not deliberately changed.

Because people didn't know that there was so much water on the earth at first, people thought that there was a lot of land, so they called it the earth at the beginning.

Because the name water polo is so ugly, and there is already a Mercury, it can't be called water polo.

Because at the time of the naming of the earth, people living on land did not know that there were so many oceans.

As we all know, our planet is a planet surrounded by water. It is a planet, and it is better to say that it is a water balloon. This is because the oceans cover more than 70 percent of the Earth's area. Later, some people showed why the original name of the earth was earth instead of water ball.

This actually reflects the understanding of the earth and water balloon. It's not that when a planet is 70 or even 80 oceans, then the planet should be called a water ball. What is a real salary star? I'm sure you're curious too, so we'll move on**.

Many scientists have given the model of the omen. I believe that in our impression, Mercury is not made up of oceans. It's an endless ocean and deep sea.

For example, our planet's Shanghai Ocean may be only a few kilometers, but the depth of the Shanghai Ocean is several kilometers, which sounds like an insufficient gap. Scientists also believe that water balloons are actually very common in the universe. At first, scientists thought that a thick atmosphere might have a water-storing environment.

But now, scientists say, when the planet is two to four times the diameter of the Earth's sand, it is enough to store water!

However, these oceans are not necessarily liquid, they can be solid, such as Neptune in the solar system, the partition and Pluto, and many other planets are considered water by scientists, but they are almost solid. It's just that these planets are too far away from their host star. Therefore, it cannot be presented in the form of liquid water.

Why was there any life born on these planets? Perhaps this is why the Earth can be a special planet in the solar system and the Milky Way. It is impossible to say that there is a planet of water.

Perhaps the conditions on this planet are very bad, such as the absence of a thick atmosphere, the absence of an atmosphere such as oxygen such as magnetic fields, so why have humans not yet found extraterrestrial life in the Milky Way?

But it is clear that there is a water balloon in the Milky Way. It also gives the earth a lot of opportunities. Look for extraterrestrial life, because these planets are not suitable for breeding life, which does not mean that this planet will exist over time in the form of aquatic planets.

For example, when our planet had 4.6 billion, it gradually became a fertile planet. Living Planet!

Because the thickness of water on the earth is only one thousandth of the diameter of the earth. Suppose a ball is 25 centimeters in diameter, stained with a layer of water on the surface, and the thickness of the water layer is millimeters, you can't call the ball a water ball.

Because human beings were born on land and have always lived on the ground, it was named Earth.

This is because the earth was first named by the ancients, when human knowledge had not yet reached this height, and there were limitations in cognition, and labor was mainly carried out on land, so they did not know that the area of the ocean was larger.

Although the ocean is larger, we still use to call it the earth because the environment we live in is mainly land.

The fact that the water on Earth comes from the sun sounds like a fallacy. Everyone knows that water h o is a substance composed of two elements, hydrogen and oxygen, and the earth's surface 2 3 or more is covered by water, so the earth is also known as the planet of water, so where does the water on the earth's surface come from? The Earth was born about 4.6 billion years ago in ancient times, and the first prototype of the Earth was created with the formation of the solar system.

Before the formation of the solar system, due to the "supernovae**" in the more ancient period, the "primordial nebula of the solar system" was formed in the position of the solar system, and a large number of cosmic dust Egyptian meteorites gradually formed the planetary system inside the solar system with the influence of gravity. This is how the Earth, as a "rocky planet" in the inner solar system, was born.

One idea is that water was captured from cosmic space when the earth was formed. When meteorites containing water condense to form the Earth, the water is sequestered in the structure of the Earth's internal material. Later, due to the increase in the temperature of the earth, the rotation speed accelerated, and under the action of the earth's self-rotating centricity, the light and lively water squeezed out of the earth's surface and appeared in a state of water vapor.

It then condenses to form precipitation, which thus constitutes surface water. There are also scientists who think that the earth's water comes from comets, because they found that many comets around the earth were originally composed of ice crystals, when the comets enter the earth's atmosphere, they will rub and generate heat, thereby releasing water, after accumulation over time, but there are hundreds of millions of comets from space, and gradually constitute water on the surface.

If the hydrogen received by the earth from the solar wind is separated from the oxygen on the earth to become water since the composition of the earth for 4.5 billion years, the total amount of hydrogen received by the earth is exactly the same as the total amount of global seawater today, according to calculations, the total amount of hydrogen obtained from the solar wind from the composition of the earth to the present day is tons, and the total amount of water in the global hydrosphere is tons, the difference between the two is not more than 10%, and the remaining water may come from comets and so on. The study concluded that the hydrogen in Earth's water comes from the sun.

Scientists point to strong evidence to support this conclusion, which is that the ratio of hydrogen to deuterium in the Earth's water system is about the same as that of the Sun, at around 6,700:1. If this idea is true, then 2 3 of the water on Earth comes from the sun, which will change people's preconceived impression that "water and fire are incompatible".

Mainly brought about by comet impacts. There are free water molecules in space, which eventually condense into water. When the comet enters the atmosphere, it rubs against the atmosphere, and the ice on its body turns into water vapor before descending to Earth.

If the hydrogen received by the earth from the solar wind is separated from the oxygen on the earth to become water since the composition of the earth for 4.5 billion years, the total amount of hydrogen received by the earth is exactly the same as the total amount of global seawater today, according to calculations, the total amount of hydrogen obtained from the solar wind from the composition of the earth to the present day is tons, and the total amount of water in the global hydrosphere is tons, the difference between the two is not more than 10%, and the remaining water may come from comets and so on. The study concluded that the hydrogen in Earth's water comes from the sun.

The first point is that the water on the earth is formed due to some special changes in the entire ocean, and the second point is that the water of the ocean is actually brought by the earth itself, and it slowly produces water from the entire ocean water.

The water on the earth is all groundwater released by underground movements, and it is also caused by some rain.

The Earth's ocean area accounts for 71% of the land area and 29% of the land area, and the earth's surface is divided into three parts land and seven parts ocean

So the answer is: ocean; Land; Seven; Three

The oceans make up about 71% of the Earth's surface area, and where does this water come from? Why is seawater salty?

Once a giant ball of water, why is it that only 70% of the Earth is now ocean?

The over-swelling population coupled with the existing freshwater is heavily polluted. As for the cost of desalination, it is relatively high, ah. It can also be not an industry with a lot of seawater, salt.
