Water resources are indispensable. The first large molecules of matter on Earth were born from the oceans. You can see the importance of water. It’s just that when the earth was first born, there was no liquid water resources, let alone the vast ocean? How is water formed? If human beings control the formation principle of water, will human beings have the ability to transform any planet without water into a planet with water?
In order to reveal the origin of water, scientists have given a variety of guesses, let’s take a look together!
The response given by most scientists is that water is formed by the accumulation of clouds above the earth. Not long after the earth was born, hydrogen atoms and oxygen atoms floating in space collided with each other to form water molecules, but because the temperature of space is too low, water Molecules quickly condensed into ice crystals. When they collided with the earth, they formed precipitation and fell to the ground, but because the earth had not formed an atmosphere at that time, even if there was water, it could not store water until 3.5 billion. A few years ago, the volcanoes on the earth began to erupt, and the magma heat wave, carbon dioxide and other gases accumulated over the earth, and a preliminary atmosphere was formed slowly, which locked the liquid water resources on the earth.
However, the liquid water resources at that time were only enough to gather the lakes and streams, and it was still quite difficult to form a vast ocean until the crustal activities began frequently, the ground collapsed, and mountains, rivers and valleys began to appear on the earth, and it slowly went through more than one billion years. Only in time did it converge into a vast ocean.
But some scientists say that the formation of Earth’s oceans comes from comets, just because comets always carry some ice crystals. When the comet collides with the earth, those ice crystals land on the earth together. However, when scientists discovered the composition of water by examining the carbonaceous chondrites when the solar system was just formed, the first two possibilities were overturned, because the earth is likely to have water resources at the beginning of its birth . It’s just that the amount of storage is far less than what it is today, but it took billions of years to reach the area that accounts for 71% of the earth today.
It’s just that no matter what kind of possibility, if human beings want to understand the formation of water to transform other planets, it is almost impossible to realize it, because it is difficult to do it manually. Most of the above three explanations are still skeptical. Where do you think the water on the earth most likely comes from?
