Water's Genesis: How Did Water Come To Earth? Biological science has developed a lot today, but research is still going on about how water came to earth. Was there a creature that lived on earth before us, who created water or is there something else behind it all? We know that three-fourths of the earth is water, most of which consists of seawater. Only 3 percent is "pure water".
It should be noted that only 3 percent of this water is drinkable for humans, but today we are making it unusable by using this clean water. According to 2025, clean water will not be available in this country and the people will be thirsty for every drop. The fear of being is created.
The simple answer is that the "water" in the world is equal to the "water" that existed from eternity, but the "clean water" that existed in eternity is much less today. We all are using water, but very few people are thinking about making clean water, can we still make water in the same way as water was produced on earth about 3 billion years ago? came into existence? The answer to this cannot be given with 100 percent certainty, but yes, there is no doubt that the truth of the 2 theories presented by scientists about the existence of water can be accepted. Following are the theories presented by.
First Theory:
As a result of chemical processes, water appeared on earth, according to this first theory, about 3 billion years ago when the earth had been formed for about a billion years and the earth was gradually cooling, then the results of chemical processes on it Water came into existence, remember that Earth also came into existence from the same cloud of hydrogen and helium gas, from which the sun and other planets of the solar system came into being.
In the past, the earth was like a ball of fire, containing various minerals. An environment that includes a certain temperature and pressure will be better for mating.
In the beginning, the Earth was very hot, due to which the atoms were combining to form new molecules (combinations of atoms), but as the Earth cooled, different atoms met and new molecules were formed, these molecules also interacted with each other. and finer molecules were formed, the first cell (the basic building block of living things), which was the first organism, hydrogen sulfide gas from volcanoes in the atmosphere, and hydrocarbons (molecules made of hydrogen, carbon, and oxygen) were taken as food and used to get energy from it.
These tiny organisms have the same basic principle of multiplying from one to two every 20 minutes, so their population increased rapidly and many generations were born, as the evolutionary process began. Therefore, later generations had changes compared to their ancestors and they started making oxygen gas in the atmosphere.
Along with their population, oxygen gas increased and those organisms whose main food was not oxygen but hydrogen sulfide, their population started to die and disappear. Gradually, oxygen gas began to form an "ozone belt" around the Earth, along with oxygen mixed with other minerals in the soil, and this chemical reaction resulted in a water molecule consisting of two hydrogen atoms and one hydrogen atom. Atoms are made of oxygen.
This process is called chemical reduction, because there was an abundance of both hydrogen (in minerals) and free oxygen (in the atmosphere), water began to form rapidly and all the craters on Earth filled with water and sunlight. So it was already there, so the process of cloud formation and the rains also started, which cooled the earth further and allowed different types of organisms to flourish.
Second Theory:
Water brought to Earth by meteors In the 20th century, scientists learned a lot about meteors and comets. It would not be wrong if we call them the debris left over from the formation of the planets and the sun. Scientists also observed the stones falling on the ground, what are these stones made of?
Their examination not only gave us a lot of information about the condition of this Earth and the rest of the planets but also found out that there is water in them! Water had not been seen on any other planet, so they were very surprised at this discovery. Scientists also found out from the research that these asteroids rained on the earth for many years immediately after the formation of the earth and it is possible that these Asteroids brought water with them to earth.
This does not mean that the existence of water on the earth was only due to the rain of asteroids, but most of this water came into existence due to chemical reduction and some part came due to these asteroids. However, these two theories Neither one of them can be said to be wrong because both of them are proven by arguments. Can last up to 5 days without water. Therefore, we must save clean water from being wasted, so that we can live in peace and our future generations can live a better life.
