Answer» ACCEPT AS BEST 👍👍👍👍👍👍 Earth, our home, is the third planet from the sun. It's the only planet known to have an atmosphere containing free oxygen, oceans of water on its surface and, of course, life. Earth is the fifth largest of the planets in the solar system. It's smaller than the four gas giants —Jupiter,Saturn,UranusandNeptune— but larger than the three other rocky planets,Mercury,MarsandVenus. Earth has a diameter of roughly 8,000 miles (13,000 kilometers) and is round because gravity pulls matter into a ball. But, it's not perfectly round. Earth is really an "oblate spheroid," because its spin causes it to be squashed at its poles and swollen at the equator. Water covers roughly 71 percent of Earth's surface, and most of that is in the oceans. About a fifth ofEarth's atmosphereconsists of oxygen, produced by plants. While scientists have been studying our planet for centuries, much has been learned in recent decades by studyingpictures of Earth from space. Earth is the third planet from the Sun and the fifth largest in our solar system. It is the only planet that we know of that can house living things, from plants to animals to humans – even though it has not always been able to do so.
