For Sale - Earth
The only known planet to support life!
What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon. The processes that shape the Earth and its environment constantly cycle elements through the planet.
Several billion years ago, the surface of our Earth began forming into puzzle pieces called plates. This process trapped our atmospheric carbon dioxide into rocks and stabilized our climate, making Earth habitable.
