Presentation Transcript

  1. The Earth as a System Earth’s Spheres

  2. What is a System? A set of connecteditems or devices that operate together

  3. Earth System Science (ESS) • The study of the interactions between and among events and Earth’s spheres • A relatively new science (1988)

  4. Earth’s Sphere • Atmosphere • Hydrosphere • Lithosphere • Biosphere • Cryosphere

  5. Atmosphere • A gaseous sphere and it envelopes the Earth, • Consists of a mixture of gases composed primarily of nitrogen, oxygen, carbon dioxide, and water vapor.

  6. Hydrosphere • All of the water on Earth • 71% of the earth is covered by water and only 29% is terra firma

  7. Lithosphere • The Earth's solid surface, often called the crust of the earth. It includes continental and oceanic crust as well as the various layers of the Earth's interior.

  8. Biosphere • All life on earth, including man, and all organisms. • The life zone on our planet distinguishes our planet from the others in the solar system.

  9. Interconnected Spheres • Spheres are closely connected • Changes are often chain reactions • A change in one sphere results in changes in others - called an event • Forest fire destroys plants in an area • Interactions between spheres • No plants => erosion • Soil in water => increased turbidity (muddy water) • Turbidity => impacts water plants/animals
