5 Theories of the Formation of the Earth According to Experts (Full Discussion)

5 Theories of the Formation of the Earth According to Experts (Full Discussion) – Earth is the planet that we live in because only Earth is a planet that has Earth's gravity, then what was the process of the formation of the Earth? Here we will answer the questions that you will find in this post.

There are several things that we will discuss where the discussion is about complete expert theories. Now to find out what the theories of the experts that we will discuss, we immediately start with the article below.

5 Theories of the Formation of the Earth According to Experts (Full Discussion)

First, let's discuss the meaning of the earth first.

Understanding Earth

Earth is a place inhabited by living things. Approximately 250 million years ago the shape of the continental crust on Earth was mostly land, better known as Pangea.

Approximately 200 million years ago Pangea split into two large continents into Laurasia which is now divided into North America, Europe, and several parts of the world. parts of Central Asia and East Asia, and another large continent is Gondwana which is divided into South America, Africa, India, Australia and parts of Asia which other. Then parts of these two large continents split and drifted away, causing collisions with other parts.

As a planet that is home to living things, the earth is composed of several layers of the earth. Where has a lot of materials for the formation of the earth, as well as all the natural wealth contained in the earth. The earth's surface has different shapes, starting from land, oceans, mountains, lakes, hills, and many others.

Earth is one of the planets that enter the solar system in the universe but the earth is not just silent as we think so far, On the other hand, the earth rotates on its axis or what is often called rotation and moves around the sun or is often called revolution and the center of the system Sun.

All of that is what causes day and night and the tides and ebbs of sea water. Because of all that, the process of the formation of the earth was also caused by the formation of the solar system.

Earth Formation

The formation of the earth consists of the following theories

1. The Fog Theory Or What It Is Often Called (Nebula)

Since BC, experts have been thinking about how the process of the earth. And one of them is the theory of fog or the so-called nebula introduced by Immanuel Kant in 1755 as well as Pierre de Laplace in 1796. Where they are both famous for Kant Laplace's theory of fog.

The theory says that in the universe there is gas that gathers into a mist or nebula. Where the attractive force between gases which then forms a very large collection of fog and spins faster. Where the rotation process is very fast, the fog material at the equator is thrown and separated and condensed due to cooling.

In the ejected part it becomes the planets in the solar system. The nebula theory is divided into several stages.

The sun and the planets are still gaseous, where the fog is still very thick and large. The mist is still spinning and twisting strongly and compaction occurs at the center of the circle and then forms the sun.

Then at the same time other matter forms into a mass smaller than the sun and then becomes a planet, and moves around the sun. Then the material gets bigger and always makes regular movements around the sun in a fixed orbit and then forms the level of the solar family.

2. Planetistic Theory

Since the early 20th century, FOrest Ray Moulton an American astronomer and his colleagues Thomas C. Chamberlain geologists, put forward the theory of the planetesimal hypothesis, that the sun was formed from a mass of gas that very large mass, when there is another star that passes and is very close and almost occurs crash. Too close the trajectory affects the gravitational force with the two stars which results in the attraction of gas and light matter that is on the edge.

The influence of gravity causes matter to be thrown and leave the sun's surface and the star's surface. The ejected material shrinks and creates planetsimal lumps. Then the planetesimals cooled and condensed to form planets around the sun.

3. Tori Tidal Gas (Tidal)

The theory put forward James Jeans and Harold Jeffrey in 1918, a large star that approached the sun a short distance, which eventually made the tides on the sun's body, when the sun was in a gaseous state. The cause of the tides is the mass of the moon and the distance between the moon and the earth is 60 times the radius of the earth's orbit.

However, if a star whose mass approaches its mass with the sun approaching, it will form a kind of mountain wave on the sun's body, which occurs because of the star's attraction. The mountains were going to be incredibly high. Then formed a kind of very large incandescent tongue, which stuck out by the mass of the sun and pointed towards the big star. Gradually these columns will break and then will become separate objects.

In this hot tongue there is a condensation of gases and eventually these columns will break apart, then separate into separate objects, namely the planets. The big star that caused the pull on the parts of the sun's body earlier, continued its journey in the universe. So that gradually will lose its influence on the planet that was shaped earlier.

The planets will revolve around the sun but when around the big planets the cooling process will be slow while on the small planets it will run faster.

4. Twin Star Theory

The theory put forward by an astronomer R.A Lyttleton, this theory explains that galaxies originated from a combination of twin stars.

Where one of the stars exploded makes a lot of material thrown. The unexploded star is called the sun and the exploding star becomes the planets that revolve around the sun.

5. Big Bang Theory

The big bang theory explains that the earth came from tens of billions of years ago. Where there is a very large cloud of fog spinning on its axis. The spin allows the small parts to be thrown while the large parts come together and become the center of the formation of a giant disc.

The giant clump exploded and formed galaxies and nebulae. About 4.6 billion years The freezing that occurred made the nebulae form a galaxy called the Milky Way galaxy and then the solar system was formed. The light parts that are thrown off form solid lumps. And those clumps formed the planets.

A few explanations about 5 Theories of the Formation of the Earth According to Experts (Full Discussion) explained by About Knowledge. Earth is the only planet that has gravity so it can be a place to live live so preserve this earth and take care of our earth well for future generations to come come. Hope it is useful.
