Water is circulating, some of the water is absorbed, and some is released. It's not going to get drier and drier, and the water molecules are basically made up of H2 and O, unless all the water is electrolyzed, but I'm sure no one can do that, and then people can make it chemically. And more?
Melting icebergs will indeed spread over a good part of the continent, but it can be embankmented, so no problem. Will it turn into a water polo? I don't think there will be that day.
Because the atmosphere has now been seriously damaged, at a certain time, many things in space will be able to fall into the earth without hindrance, causing unimaginable racial destruction. Recently, a star 8,000 light-years away from the earth is fast**, and what light will be released may be aimed at the earth to produce ozone destruction, followed by the earth's self-detonation, and then regrouping. Of course, I don't know what will happen after the reorganization.
But rest assured, 8,000 light years, even if it explodes now, it will not reach the earth until 8,000 years later.
I don't think the earth will wait for that day, and soon, the earth's ozone will become thinner and thinner, and the danger of extinction is inevitable, because now human beings are simply powerless and powerless. So, environmental pollution will be a big problem. Aren't humans always looking for aliens?
But it is very likely that when you find that day, you will fight for hegemony, that is either the death of the earth, or the death of aliens, will you believe that two different galaxies have no connection, and aliens with very terrifying appearances will not fight for hegemony? If they all have such wisdom. And perhaps, they have a higher intelligence, like orangutans, whose memory is many times that of humans.
Live each day and leave it to those who can do it!
-
Judging by the current trend, it should be, but the humans who are still alive should not see the day come ...
-
No, with human activities and nature's volcanic activity and various chemical reactions, water molecules are constantly broken down and synthesized into other substances, and there will only be less and less water on the earth, and the earth will only get drier. Of course, this time will be long.
-
Is there anything worth looking into, will you wait until that day?
-
No, it won't. Although the Earth's temperature is increasing, the glaciers at the poles are melting.
This would make it possible to flood most of the land.
But a lot can happen before that.
Let's say a meteorite hits the Earth.
If it really happens.
In addition, the size of its meteorite is very large.
Then the earth will turn into a fireball.
A fireball with a temperature of more than 500 degrees
And it burns non-stop.
Similar to the sun now.
When all combustible substances are burned out, the air is consumed.
Because a large amount of water in the ocean evaporates.
Formation of rain. The rain is falling.
Slowly, the living conditions of the earth are getting better.
Life reappeared.
But for now.
After humanity has used up all its resources.
What will happen?
It's going to be like Mars.
There is no water. (The water on Mars is a liquid gas.)
Life is gone. If so, I want to give birth to life again.
Then it's unlikely.
Maybe a bit off topic.
What I want to say is that cherishing resources is important for all life.

01 In ancient times, people lived on land, and the scope of their activities and observations was small, so they could not recognize the whole picture of the earth, and the ancient navigation technology was backward, so they did not know the vast area of the ocean, so the name of the earth was not called water ball, but the earth.
Earth is the only name that is not derived from Greek or Roshen horse mythology. The word earth comes from Old English and Germanic languages. In Roman mythology, the goddess of the earth was called Tellus the Fertile Land (Greek: gaia, Mother Earth).
The total area of the earth's surface is about 100 million square kilometers, the water area is about 100 million square kilometers, accounting for about 71% of the total surface area of the earth, and the land area is about 100 million square kilometers, accounting for 29% of the total surface area of the earth. When seen from space, the Earth looks like a water balloon, which is blue in color, and it should be called a water balloon.
But when the earth was named, the range of people's activities was small, the range of observation was small, and they saw that there was a vast land around them, and the people of Soli called the earth where we lived. The name was given at a time when people not only thought that the land in the world was greater than the sea, but even that the land would always be flat. Earth is the third planet in the solar system from the inside to the outside, and it is also the terrestrial planet with the largest diameter, mass, and density in the system.
The human beings who live on the earth often refer to the earth as the world.
-
The earth has existed for 4.6 billion years, and the disappearance and increase of water can only be seen with an accelerated lens in a long time.
The earth is our home for survival, and what we have to do in this life is to take care of our home, protect water resources, and protect our living environment.
-
No, there was much water at the time of the formation of the earth, and it is still much water today.
We feel that water will be consumed tomorrow, but in fact, in the earth's atmosphere, water is infinitely circulating.
-
Water should be a consumable substance and will not increase, but the amount of water on the earth is very large for human drinking, and it will take thousands of years to verify that it is depleted.
-
Water will be transformed into other substances through chemical reactions, and other substances will also be turned into water through chemical reactions, but the amount of water in the area is too large. These chemical reactions are relatively rare.
Hope, thank you.

Five million years ago, human beings were born on the earth, and they have always been down-to-earth and "native-born", so they call the earth "the mother of mankind". The Chinese emperor said: "Under the whole world, it is not the king's land", and it has always been the land of human beings.
When mankind entered the space age, astronauts looked down at the earth from outside the sky and agreed that the earth is a blue as the base color, inlaid with orange and yellow colored spheres, the continent seems to be some islands in the ocean, and the whole earth looks like a blue crystal "water ball".
In fact, it is the ocean that wraps the surface of the earth, not only vast, with an area of 100 million square kilometers, accounting for the surface area of the earth, but also very deep, 70% of the ocean water depth is more than 1,000 meters, the average water depth is 3,792 meters, the deepest trench is 11,031 meters, and the total volume of seawater is 100 million cubic kilometers, accounting for the total amount of water on the earth. In the southern hemisphere of the earth, the ocean accounts for 81%, and even in the northern hemisphere, where there is more land, the ocean accounts for 61%. So, the earth is a veritable blue "water ball".
-
And he's right, that of the nine planets, only Earth is liquid.
-
This is because the ocean area on the earth's surface accounts for 71%, that is, most of the earth's surface, and there is a lot of water storage, and the thickness of the surface water can reach tens of meters when tiled on the ground.
Earth is one of the eight planets in the solar system, the third planet in order from near to far, and it is also the terrestrial planet with the largest diameter, mass and density in the solar system, 100 million kilometers away from the sun.
The Earth rotates from west to east while revolving around the Sun. It is 4,04.6 billion years old, and it has a natural satellite, the Moon, which forms a celestial system, the Earth-Moon System. It originated from the primordial solar nebula 4.6 billion years ago.
The radius of the Earth's equator is kilometers, the polar radius is kilometers, the average radius is about 6371 kilometers, and the circumference of the equator is about 40076 kilometers. The surface area of the earth is 100 million square kilometers, and 29% of the land area is land except for the ocean area.
The interior of the earth has a core, mantle, and crust structure, and the outside of the earth has a hydrosphere, atmosphere, and magnetic field. The Earth is the only celestial body in the universe where life is known to exist, and it is home to millions of living beings, including humans.

1. Only on Earth there is water.
2. More than two-thirds of the Earth is covered by water.
-
Because the total area of water on the surface of the earth accounts for 71 of the total area of the earth, and the total land area only accounts for 29 of the total area of the earth, the earth is a blue planet in space, so the earth is also called the water ball.
-
Because nearly seventy percent of the earth is water!Looking at the earth in the universe, most of it is blue and beautiful!
-
Because the Earth has 7 points of ocean, it looks like a water balloon from outer space.
-
Seven tenths of the Earth's water and only three-tenths of its land area. Hence the earth is called a water ball.
-
More than 70% of the earth is ocean, and the rest is land, so it is called water ball.
-
Because more than 70% of the earth's surface is covered by blue oceans, lakes and rivers occupy only a small part of the earth's surface waters. The liquid water layer on the Earth's surface, called the hydrosphere, has been formed for at least 3 billion years.
The water area of the Earth is larger than the land area, and it looks like a blue water ball from outer space.
-
Because most of the Earth's surface is covered by oceans, it looks like a blue water ball from outer space.
-
The land occupies three-tenths and the ocean occupies seven-tenths, do you think it should be called water polo?
-
Seventy-one percent of the sphere's surface is covered by a blue ocean.
-
Because 70% of it is water, although not all of it can be drunk.
-
Because 71% of the Earth's surface is covered by water.
-
Because our ancestors lived on the land and were full of unknowns about the sea, believing that it was an unknown world or a dark abyss, and that only the land in which they lived was given by God, they called it the earth.
With the rapid development of science and technology, the opening of new shipping routes, and the formation of the world market, the world has been connected together, and mankind has discovered that most of the earth is full of oceans, that is, we are familiar with the theory of three parts of land and seven points of ocean, which looks like a blue water ball surrounded by water from outer space, so it is also called a water ball.
-
Earth is the only planet in the solar system that has liquid water on its surface. Water covers 71% of the Earth's surface (seawater, freshwater. Water is present in all five oceans and seven continents.
The combination of the Earth's solar orbit, volcanic activity, gravity, the greenhouse effect, the geomagnetic field, and an oxygen-rich atmosphere makes the Earth a water planet with an atmosphere, an ozone layer, and habitation.
So on Earth, there are three parts of land and seven parts of oceans.
-
Because about 70% of the Earth is oceans.
-
The only sphere that has water to live on.
-
Let's start with the description of Earth on Wikipedia:
Earth is the only planet in the solar system that has liquid water on its surface. Water covers 71% of the Earth's surface (seawater, freshwater. Water is present in all five oceans and seven continents.
The combination of Earth's solar orbit, volcanic activity, gravity, the greenhouse effect, the geomagnetic field, and an oxygen-rich atmosphere makes Earth a planet of water.
So on Earth, there are three parts of land and seven parts of oceans.
-
Because there is a lot of liquid water,
No, there are generally two forms of population growth: "J" curve and "S" curve. The former must be in an ideal state: sufficient space and food, a suitable climate, no natural predators, etc., which is basically non-existent in the natural state. >>>More
The change is not obvious, not for the time being.
Because the vertical stability of the earth's gravity is generally recognized in our daily life, the earth's natural force, that is, the earth's gravity, is commonly known as the "earth's fixed gravity" (also to distinguish particle microgravity). The theory of studying the meaning, function, laws and characteristics of "the earth's natural force, that is, the earth's fixed gravity", is the "earth's fixed gravity", referred to as "the earth's gravity", which is the earth's natural force generated by the earth's material mass as a whole, that is, the earth's gravity, which occurs in and to the center of the sphere, also known as the spherical gravity. The natural force of the earth, that is, the energy of the earth's body (earth) and the earth's outer space (sky) reached by the earth's gravitational force, condenses in the direction of the earth's core, and this cohesion is carried out in a vertical downward way to stabilize the energy of the things it reaches. >>>More
Because the earth is the only planet with life, and water is the source of life.
