There are many theories regarding the origin of earth. But it has not been conclusively proven. The theories only try to unravel the mystery of the origin of the Earth. Some of them are religious or philosophical and the others are scientific. Among the scientific theories like the Steady Earth theory, the Big **** theory, the Pulsating theory, etc.
The Big **** theory is the more popular and widely accepted one. Earth is one of the planets in our solar system. But it is the only planet on which life has evolved. Earth is said to have been formed at least 4.5 billion years ago. The temperature then was so high that it was a white hot mass of molten rock.
It witnessed frequent volcanic eruptions and large collisions. A large number of comets and meteors collided with the earth in its early years of evolution. One such large collision is believed to have caused the earth’* tilt and the formation of the Moon. These factors along with many others formulated the weather and climate of the earth.
The crust was still hot and water was in the form of steam. Further cooling condensed the steam to form clouds and then rains began to pour in torrents. This continuous downpour formed lakes, rivers, oceans, and seas. The rains and winds eroded the valleys and Mountains. The erosion formed rocks to break and form tiny particles of sand and mud. The continuous erosion formed soil and the ocean floor.
