Where and how did the water come from
Where and how did the water come from?
A: Biological science has advanced a lot, but research is still going on about how water came to earth. Was there any creature on earth before us that made water or is there some other reason behind it all?
We know that three-quarters of the earth is water and most of it is seawater while only 3% is "clean water".
It should be noted that we humans are only able to drink this 3% share, but today we are making this unusable by using this clean water relentlessly.
If water continues to be used at the current rate in Pakistan, then according to experts, clean water will not be available in this country till 2025 and the people will miss every single drop.
Many people have been found to say, "On the one hand, scientists say that the world's water has been equal since time immemorial, and on the other hand, there is a fear of running out of water. What is the truth?"
The simple answer is that "water" in the world is equal to "water" from eternity, but "clean water" today is much less than "clean water" from eternity.
We are all using water, but there are very few people who are thinking about making clean water, but can we still make water today as water existed on earth about 3 billion years ago? Did I come?
This cannot be answered with 100% certainty, but yes, there is no doubt that the two theories put forward by scientists about the existence of water can be accepted as true by scientists. The ideas presented are as follows.
As a result of the chemical process, water came into existence on earth
According to this first theory, 3 billion years ago, when the Earth was about one billion years old and the Earth was slowly cooling down, water came into being as a result of a chemical reaction. Remember that the Earth is also hydrogen. And from the same cloud of helium gas that gave rise to the solar system's sun and the rest of the planets.
In the past, the earth was like a ball of fire, containing various minerals. We know that an atom, which is the basic armor of matter, will form a relationship with another atom when it is surrounded by An environment that includes a specific temperature and pressure that would be better for matching.
In the beginning, the earth was very hot, so the atoms came together to form new molecules (a collection of atoms), but as the earth cooled, different atoms were found and new molecules were formed. The first cell (the core of living things) that was the first living thing to form was hydrogen sulfide gas from a volcano in the atmosphere and the hydrocarbons (molecules in the earth) Take it as food and get energy from it.
As their population grew, so did the oxygen and gas, and the living creatures whose main food was not oxygen but hydrogen sulfide began to die and perished.
Oxygen gas gradually formed an "ozone belt" around the planet, as well as oxygen found in other minerals in the soil and this chemical process resulted in a water molecule containing 2 atoms of hydrogen and one atom of oxygen. Comes into being.
This process is called chemical reduction, because there was an abundance of both hydrogen (in minerals) and free oxygen (in the air), so water also began to form rapidly and all the pits on the earth were filled with water. It was already there, so the process of cloud formation and the onset of rains also began, which made the earth cooler and colder, allowing different kinds of living things to flourish.
The second theory
The arrival of water on the earth through the meteor
In the twentieth century, scientists have discovered a lot of new things about meteors and comets. We know that meteors are rocky substances that came into being with the formation of the solar system and if we continue to form them into planets and the sun. It would not be wrong to say leftover garbage.
Scientists have also observed these rocks falling to the ground. What do these rocks consist of? Their tests not only gave us a lot of information about the condition of the earth and the rest of the planets but also showed that they contain water !!
Since at that time scientists had not seen water on any planet other than Earth in the solar system, they were astonished at this discovery. It has been raining on these planets and it is very possible that these planets have brought water with them to the earth.
This does not mean that the existence of water on Earth came only from the rain of the planets, but that most of this water came into being due to chemical reductions and partly due to these planets.
However, neither of these two theories can be refuted, because both arguments prove that the existence of water on earth has its own significance.
We all know the importance of water in our lives, we can live without water for a maximum of 5 days after which our death is certain so we must avoid wasting clean water so that we May we live in peace and may our generations live a better life.
