"The origin of the Earth"

Audrey Yanice Barria Sanchez, Isabella Hernandez, Sofia Melendez

Earth originated from the Big Bang, which occurred around 13.8 billion years ago, leading to the formation of galaxies and stars. About 4.6 billion years ago, a cloud of gas and dust in the Milky Way collapsed under gravity, forming the Sun and a surrounding disk of material. Through a process of accretion, particles in this disk collided and merged, eventually forming Earth and other planets. As Earth cooled, it developed a solid crust and an atmosphere, laying the foundation for the emergence of life.
