Earth is the only living planet, it is the 3rd planet from the sun. Earth has four spheres. The four spheres are called Biosphere, Hydrosphere, Atmosphere, and Lithosphere. The biosphere is all life on Earth. Here are some examples of the biosphere grass, trees, plants, animals and other living things. The hydrosphere is anything that includes water. For example, Lakes, Oceans, Ponds, rivers, snow, and anything else that has to do with water.

The atmosphere is the envelope of gases surrounding the Earth or any other planet. The atmosphere is made out of a mixture of gases, for example, mostly nitrogen, oxygen, argon, and carbon dioxide. The Lithosphere is the rigid outer part of the Earth, consisting of the crust and upper mantle.
