Detailed explanation-1: -Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.
Detailed explanation-2: -Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years.
Detailed explanation-3: -The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it.
Detailed explanation-4: -The Earth formed more than 4 billion years ago along with the other planets in our solar system. The early Earth had no ozone layer and was probably very hot. The early Earth also had no free oxygen. Without an oxygen atmosphere very few things could live on the early Earth.
