NASA Earth, our home, is the third planet from the sun. It is the only planet known to have an atmosphere containing free oxygen, oceans of liquid water on its surface, and, of course, life. Earth is the fifth largest of the planets in the solar system — smaller than the four gas giants, JupiterSaturnUranus and Neptunebut larger than the three other rocky planets, MercuryMars and Venus.
Earth has a diameter of roughly 8, miles 13, kilometersand is round because gravity pulls matter into a ball, although it is not perfectly round, instead being more of an "oblate spheroid" whose spin causes it to be squashed at its poles and swollen at the equator.
While scientists have been studying our planet for centuries, much has been learned in recent decades by studying pictures of Earth from space. Orbital Earth and planet essay Earth spins on an imaginary line called an axis that runs from the North Pole to the South Pole, while also orbiting the sun.
It takes Earth This means the northern and southern hemispheres will sometimes point toward or away from the sun depending on the time of year, varying the amount of light they receive and causing the seasons.
Earth happens to lie within the so-called "Goldilocks zone" around its star, where temperatures are just right to maintain liquid water on its surface. Average distance from the sun: As the nebula collapsed because of its gravity, it spun faster and flattened into a disk.
Most of the material was pulled toward the center to form the sun. Other particles within the disk collided and stuck together to form ever-larger bodies, including Earth.
The solar wind from the sun was so powerful that it swept away most of the lighter elements, such as hydrogen and helium, from the innermost worlds, rendering Earth and its siblings into small, rocky planets. Scientists think Earth started off as a waterless mass of rock.
The history of Earth is divided into four eons — starting with the earliest, these are the Hadean, Archean, Proterozoic and Phanerozoic. The first three eons, which together lasted nearly 4 billion years, are together known as the Precambrian.
Evidence for life has been found in the Archaean about 3. The Phanerozoic is divided into three eras — starting with the earliest, these are the Paleozoic, Mesozoic, and Cenozoic. The Paleozoic Era saw the development of many kinds of animals and plants in the seas and on land, the Mesozoic Era was the age of dinosaurs, and the Cenozoic Era we are in currently is the age of mammals.
Most of the fossils seen in Paleozoic rocks are invertebrate animals lacking backbones, such as corals, mollusks and trilobites. Fish are first found about million years ago, while amphibians appear roughly million years ago.Plants.
