Facts about Earth

  • Earth is the third planet from the Sun and the only astronomical object known to support life.
  • 70.8% of Earth is covered with water.
  • Earth’s outer layer is divided into several rigid tectonic plates that migrate across the surface over many millions of years, while its interior remains active with a solid iron inner core, a liquid outer core that generates Earth’s magnetic field, and a convective mantle that drives plate tectonics.
  • Earth’s atmosphere consists mostly of nitrogen and oxygen.
  • Earth’s gravity interacts with other objects in space, especially the Moon, which is Earth’s only natural satellite.
  • Earth orbits around the Sun in about 365.25 days.
  • The gravitational interaction between Earth and the Moon causes tides, stabilizes Earth’s orientation on its axis, and gradually slows its rotation.
  • Earth is the densest planet in the Solar System and the largest and most massive of the four rocky planets.
  • Earth formed over 4.5 billion years ago. Within the first billion years of Earth’s history, life appeared in the oceans.
  • Over 99% of all species that ever lived on Earth are extinct.
  • The shape of Earth is nearly spherical. There is a small flattening at the poles and bulging around the equator due to Earth’s rotation.
  • The major heat-producing isotopes within Earth are potassium-40, uranium-238, and thorium-232.
  • At the center, the temperature may be up to 6,000 °C (10,830 °F)
  • The elevation of the land surface varies from the low point of −418 m (−1,371 ft) at the Dead Sea, to a maximum altitude of 8,848 m (29,029 ft) at the top of Mount Everest. The mean height of land above sea level is about 797 m (2,615 ft).
