SOLUTION
Earth formed about 4.5 billion years ago through a process called accretion, where smaller objects in the solar system combined to form larger ones.
The early Earth was a hot, molten mass that eventually cooled and solidified to form a crust. The release of gas and dust created the early atmosphere, and the formation of oceans is thought to have been influenced by volcanic activity and the impact of comets and asteroids. Over time, the evolution of life on Earth has shaped the planet in countless ways.
