You must know a lot about the Earth. Then interesting information related to it given in the article such as;
1. What was the primeval structure of the Earth?
2. What changes occurred in the structure of the Earth?
3. How was Earth's gaseous atmosphere?
4. How did life begin on Earth?
1. What was the primeval structure of the Earth?
So first of all, we talk about the initial structure of the Earth. Our Solar System and newborn star around which dust and rock were circling.
There was no sign of Earth her, but the process of formation of our Earth had started. Its foundation was ready.
The rock and dust are now joining together due to gravity. After may million years, they had turned into a faint sphere, but now it could not be called our Earth because it was very hot now. It was similar to today's Venus.
About 6.5 million years ago, the surface of the Earth was completely covered with boiling LAVA. At that time, the temperature of the Earth's surface was about 1200 degrees Celsius. So it was no less than hell, and here was Oxygen not present.
2. What changes occurred in the structure of the Earth?
There was a constant rain of Asteroid on the Earth, which was forming a river of boiling LAVA several Kilometers long on the surface of the Earth. And these asteroids were a distant neighbor of the Earth, which were constantly colliding with it.
A new planet, "Thia," was moving towards the Earth at a speed of 15 Kilo Meter Per Sec.(which was twenty Kilometers more than the speed of a bullet), which caused the Moon formation.
By now, so many rocks and pieces had gathered around the Earth like Saturn, which was exactly like the ring of Saturn. The first ring was between the Earth and the Moon. The second ring was behind the Moon due to which the asteroids were continuously raining on the Earth.
Now, this ring gradually turned into a three thousand Kilometer wide spherical body due to gravity. And this gave birth gave to the Earth's Moon, Which was very closed to the Earth.
Due to which it was continuously exerting its effect on the Earth. And its surface was very hot, and there was no rain on the surface of this Moon yet.
After that, the gas joints of our Solar System began to change. And this change creates a gravitational moss between asteroids and comets into the Solar System interior.
And at the same time, these asteroids collided, causing pit on the Moon. And this period was called "The Late Heavy Bombardment." At that time, the Moon shone like a big lander in the sky. And it was so close to the Earth that its gravity was affecting our Earth 25 times more than it is today.
Then one on our Earth, it was not only 24 hours but for 6 hours. And due to this, the waves in the LAVA river of the Earth used to rise 20 times more than today's sea waves.
Over time the Moon gradually started to move away from the Earth. And due to this rotation of the Earth started slowing down, and the LAVA rivers started cooling. And the surface of the Earth formed.
3. How was Earth's gaseous atmosphere?
At that time, there was only one gas in the Earth's atmosphere, "Methane," which had harmful to life.
During the "Late Heavy Bombardment," there were also frequent comets on the Earth who transported water to the Earth. These bodies contain frozen crystal of ice and also brought Nitrogen gas into the Earth's atmosphere.
The Earth was now surrounded by sea from all sides, but now there was no land to keep feet on the Earth nor Oxygen to breathe,
About three meteorites rained 7 billion years ago; they bought mineral along with them, they also transported Caron, Protein, Amino Acids from the space to ocean.
But the temperature at a depth of the sea was very low. Sunlight could not reach here. But there were small natural chimneys in the depth of the sea. And this brought the first seed of life on the Earth
4. How did life begin on Earth?
A. What were the first seeds of life?
Due to the reaction of minerals and chemicals, one of the first unicellular organism was born in the depth of the ocean on the Earth. The bacteria started growing very fast in the sea; now, this water was filled with these microorganisms.
About 3.5 billion years ago, the number of these bacteria inside the sea had increased so much. That they had joined together and turned into some stone-like structure called "STROMATOLITES." One rock was a complete colony of bacteria in itself.
These bacteria converted Sunlight into food. This process is known as "PHOTOSYNTHESIS." In this process, they used to create gaseous produce, which was Oxygen gas.
For almost two billion years, the amount of Oxygen on Earth kept increasing continuously. Up to about 1.5 billion years ago, there was no complex like fixing on the Earth. There was a small island on the Earth which were surrounded by water.
But then the Earth's crust began to stir; due to this, the surface of the Earth broke in many tectonic plates. Then because of the movement in these plates. All the small islands were joined together. And the supercontinent was created. Its name was "RODINIA."
B. What was the role of Carbon Dioxide on early Earth?
At that time, the temperature of the Earth was 30 degrees Celsius, and one day it was 14 hours. About 85 million years ago, the Earth's outline began to change again.
The supercontinents parts broke, and LAVA started coming out from within the Earth due to volcanic eruption. Due to these explosions, the amount of Carbon Dixoide on Earth increased. Now the sky of the Earth was surrounded by Carbon Dioxide clouds. These clouds started to get Acidic Rain.
Due to this, most of the Carbon Dioxide of the Earth began to freeze as a thick layer of Carbon on the Rock of the Earth, Which was raining this rain. This led to a huge reduction in Carbon Dioxide in the atmosphere.
And the Earth's atmosphere was not able to resist the heat of the Sun itself, which caused the Earth's temperature to start increasing again due to which ice stored on the Earth started coming back to normal again.
About 54 million years ago, the Earth's ice completely melted. And the sea appeared to be a completely new world. Due to the dominance of Oxygen, the marine unicellular organisms had evolved into many other forms.
C. How did the development of Organisms on Earth?
There were strange sea plants and creatures here. Also, there was a giant sea monster, "ENAMELOCARISH." These sun complexes were new pieces of a multicellular organism that evolved from unicellular microbes.
PACAYA was only five Centimeters tall, but he had developed something very special in our body, which was going to become an important part of our body. These were the first creature that had a backbone, which was to we met later.
About 70 million years ago, the Earth had become somewhat familiar now. The supercontinent of the Earth was now divided into many more parts. And this was due to harmful rays from the Sun falling on the Earth.
Over time, the Oxygen in the atmosphere was absorbed by the Sun's ultraviolet radiation. Due to this, little algae developed on the surface of the Earth. And these become the first land glands of the Earth.
TIKETALI fish living in the sea tried to live on the Earth outside the sea for the first time. It used its fringe as legs, and over time, it stayed on the ground for a long time. Due to which its limbs develop considerably.
Knowing this after the development sequence of about one and a half million years ago, They were now fully fit to live on the land. And these were called "TETRAPODS."
Around 34 million years ago, TETRAPODS were fully developed and became fully habitable on land. There were the creatures that later evolved into Dinosource, birds, mammals, and finally, humans were to happen.
The evolutionary process of the organism was continuing with time. But the Eart atmosphere was changing very fast due to volcanic eruption again. The temperature of the Earth had increased very much. This causes a great Famine for the Earth.
In this Famine, 95% of the Earth's organisms were eliminated. And some of the creatures that were left started living inside the ground to escape the heat and started eating anything to satisfy hunger.
About 200 million years ago, volcanic eruption created new terrains of which, "PANGEA." Now the Earth had become much like today, after the passing of such great Famine, the Earth returns to normals.
Then new trees and plants started growing on the surface of the Earth. And 5% of organisms that had survived on the Earth were also developed now completely new piece was born they were "DIANOSOURCES."
The history of the Dianosources is another broad topic, so I will give you knowledge about it in another article.
Thus the Earth has been formed, and life began on it. Ultimately you can get interesting knowledge from here about the formation of the Earth on the beginning of life on it.
