How the earth was made?

 

The origin of the Earth has remained a mystery for billions of years.  Now, in a recent incident, there are indications of this mystery being exposed.  It is being told that a gas is leaking from the interior of the earth.  Actually, this is the same gas which was necessary for the nebula at the time of formation of the universe.  It is believed to be helium 3 gas, which is a rare isotope of helium gas.

creation of earth

We have told about the formation of the universe and our solar system in our old article, which you can read through the link given below, here let us understand the formation of the Earth in brief.  A Big Bang occurred approximately 13.7 billion years ago.  As a result, the universe came into existence and about 4.5 billion years ago, our solar system was formed from a cloud of dust and gases called a nebula.  These clouds continued to rotate in the shape of a disk in the universe for millions of years and came closer due to gravity, as a result of which ,

Actually, this gas was formed immediately after the Big Bang and due to this the solar nebula was formed, only after which the Earth was formed.  This is the reason why scientists are trying to know about the process of formation of the Earth through this gas.

 Helium-3 gas is present in abundance in the Earth's core.

 Now scientists are trying to estimate how much gas is leaking.  Earlier this gas used to come out from the central part of the Earth (mantle).  Now the discovery of Helium-3 leaking from the Earth's core has revealed that abundant quantity of Helium-3 gas is present in the Earth's core.

 How was the Earth's core formed?

 According to NASA, the nebula was formed from a storm of gas and dust, in which hydrogen and helium were mainly present.  The dust and gas present in the nebula were quite dispersed, but due to gravity they all stuck together and developed into clusters and then they continued to spread.  At the same time gravity also became stronger and stronger.

 Every year two kilos of helium comes out of the earth.

 About 4 billion years ago, an object one-third the size of the Earth came and collided with the Earth.  In such a situation, the earth's crust started melting once again.  Due to this, most of the helium 3 gas started coming out.  It is now estimated that even today about 2 kg of helium gas comes out from the lower part of the earth every year.

 Gradually this cluster collided with its own gravity.  When it collided, the center of the cluster became extremely hot.  After this this hot core took birth in the form of a star.

 At the time of its creation the Earth was not like it is today, rather it was as hot as a ball of fire, it had neither water nor oxygen. The Earth has gone through a long period of evolution, as a result of which life has become possible on Earth. Over time, many natural phenomena occurred, which made life possible on Earth. We will discuss some such incidents here.

Earth's place in the solar system

The first event that made life possible on Earth was Earth's location in the solar system. The area where Earth is located in the solar system is called the Goldilocks Zone. It is said. Located between Venus and Mars, this region is the only region in the entire solar system, where the Sun's energy reaches in balanced quantity. In other words, Earth is neither as hot as Venus nor as cold as Mars. Due to being in this area, water remains in liquid state on Earth.

stability of earth

We know that the Earth rotates on its axis and revolves around the Sun, due to which there are changes in day and night and seasons. But it was not possible for the Earth to remain on its axis and in such a situation life on Earth would not have been possible, this became possible due to the collision of a planet as big as Mars with the Earth.

Some time after the formation of the Earth, a planet collided with the Earth, as a result of which dust, soil, metals and other light substances from the Earth's surface started revolving around the Earth in the form of a ring in space and their accumulation formed the Moon. Construction took place. The presence of the Moon provided stability to the Earth. The gravitational force exerted by the Moon on the Earth keeps the Earth in place.

water on earth

 After stability was achieved, there was a need for water, which was not yet present in the earth.  About 500 million years after the formation of the Earth, meteorites started falling on the Earth from space.  These meteorites kept bringing water with them in the form of ice.  

 beginning of life

 Although oxygen was still not present in the Earth's atmosphere, the conditions were very favorable for the beginning of life inside the ocean.  All the elements necessary for life like ammonia, nitrogen, carbon etc. were reaching through hydrothermal vents built under the sea.  Therefore, life began as single-celled organisms.  formed in the sea with the addition of vital elements

 A Big Bang occurred approximately 13.7 billion years ago.

origin of humans

The rat-sized mammals that survived the Great Flood acquired the ability to climb trees in search of food and evolved and took the form of apes. These were Pterolapithecus. Later, due to change in climate and geographical conditions, some of these evolved into chipmunks and gorillas, while some started evolving into humans. They learned to stand on two legs, learned to hunt by turning stones into tools, discovered fire and evolved into their present form.
