All of us know that Earth is the only planet where life exist. But when we say this a simple question arises about the Beginning of Earth.So in this blog I will discuss everything about Beginning of Earth.
Earth began to form over 4.6 billion years ago from cloud of gases (mostly hydrogen and helium) and interstellar dust. In fact, Earth is still forming and cooling from the galactic implosion that had created the other stars and planetary system in our galaxy. This process has began about 13.6 billion year ago when the milky way galaxy began to form. As our solar system began to form together, the sun was formed within a cloud of dust on a gas that continued to shrink in upon itself by its own gravitational forces. This caused it undergo the fusion process and give off light, heat and other radiation. During this process, the remaining cloud of gas and dust that surrounded the sun began to form into smaller lumps called planetsimds, which eventually converted into the planets that we known today.
The earth went through a period of intense formation during its early beginning. By 3.8 to 4.1 billion years ago the earth had become a planet with an atmosphere.
