EARTH FORMATION THEORY

 == English ==

~ Kant Theory :

     In 1755, a German philosopher named Immanuel Kant arguedthat the solar system consists of the sun, earth, moon, planets,and asteroids in the beginning or the collection of star-shapednebula that resembles a cloud or a gas with a heavy mass.Through the cooling process, the nebula is transformed into the earth, moon, sun, and planets - planets.

A

~ Buffon's Theory

     At about the same time came the theory of French natural scientist George Louis Comte de Buffon Leelere. He argued that the ancient collision occurred between the sun with a comet that causes the most mass of the sun bouncing out. The mass of this bouncing into planets.

~ Theory Laplace

     A French mathematician and astronomer Pierre Simon Marquis de Laplace in 1796 suggested the earth was formed from clusters of hot gas that rotates on its axis, then formed a ring - a ring. Most of the gas ring, was thrown out and still continue to spin. A rotating gas ring will experience a cooling, thus forming a clot - a lump the ball into planets - planets, including Earth.

 

 

~ Planetisimal Theory Hypothesis

     there are early 20th century, Forest Ray Moulton, an American astronomer and colleagues TC Chamberlain, a geologist, proposed the theory Planetisimal Hypothesis, which says the sun consists of a large mass of gas mass at all, at one point was approached by a another star passing with a high speed near the sun. At the time the star passes near the sun and both are relatively close distance, then some gas mass of the sun out there is interested because of the gravity of the passing star. Most of the mass of gas out there who are interested in the track star and partly there is revolves around the sun because the sun's gravity. After passing star had passed, the mass of gas that rotates around the sun has cooled and formed a ring which gradually becomes solid and called planetisimal. Some formed planetisimal attract each other - interesting merge into a single and eventually forming planets, including Earth.

~ Tidal Theory

     Two British scientists, James Jeans and Harold Jeffreys, in 1918 put forward the theory of tidal. They say when a star passes near the sun, part attracted to the outer solar masses so as to form a kind of cigar. Parts that make this cigar would have cooled and formed the planets - planets, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, and Uranus.
