What are the 3 main characteristics of the Earth that allows life to exist?

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.

Why is Earth so special?

Earth is special because it is an ocean planet. Water covers 70 percent of Earth’s surface. Earth’s atmosphere is made mostly of nitrogen and has plenty of oxygen for us to breathe. The atmosphere also protects us from incoming meteoroids, most of which break up before they can hit the surface.

What is the habitable?

The habitable zone is the area around a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets. … The distance Earth orbits the Sun is just right for water to remain a liquid. This distance from the Sun is called the habitable zone, or the Goldilocks zone.
