  3. Basic Facts about Earth 3rd planet 7.1 billion 149,600,000 km – orbit 12,756.3 km - diameter  5.9736 x 1024 kg. or 5,973,600,000,000,000,000,000,000 kg. - mass Earth’s satellite: Moon

  4. Earth’s name & History Earth’s Greek name: Terra Mater – mother earth Roman Mythology: Goddess of Earth, Tellus – Fertile soil Copernicus ( 16th century ) Nineplanets.org Polishamericancenter.org

  5. Earth’s parts • Crust (0 – 40 km) • Upper Mantle (40 – 400 km) • Transition Region (400 – 650 km) • Lower Mantle (650 – 2,700 km) • D” Layer (2,700 – 2,890 km) • Outer Core (2,890 – 5,150 km) • Inner Core (5,150 – 6,378 km) (http://library.thinkquest.org) (http://library.thinkquest.org)

  6. Earth’s Chemical Composition 34.6% iron 29.5% oxygen 15.2% silicon 12.7% magnesium 2.4% nickle 1.9% sulfur 0.05% titanium Nineplanets.org http://1.bp.blogspot.com

  7. Atmosphere Troposphere Stratosphere Mesosphere Thermosphere Exosphere or Ionosphere

  8. Tectonic Plates North American Plate South American Plate Antartic Plate Eurasian Plate African plate Indian – Australian Plate Nazka Plate Pacific Plate

  9. Motion or Elipse Ellipse Axis is a slight tilt

  10. Magnetic Field Shields us from charged particles from the Sun The flow of liquid Iron generates electric currents.

  11. Life Factors • Temparature • Atmosphere • Water • Energy • Nutrients
