The earth as a system

The Earth as a System

Earth’s Spheres


Earth s spheres

Earth’s Spheres

  • Atmosphere

  • Hydrosphere

  • Lithosphere/ Geosphere

  • Biosphere

  • Cryosphere


Atmosphere

Atmosphere

  • The gaseous sphere that covers the Earth.

  • Consists of a mixture of gases composed primarily of nitrogen, oxygen, carbon dioxide, and water vapor.


Hydrosphere

Hydrosphere

  • All of the water on Earth

  • 71% of the earth is covered by water and only 29% is terra firma


Lithosphere

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.


Biosphere

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.


Cryosphere

Cryosphere

  • The portion of the Earth's surface where water is in a solid form

  • Snow or ice: includes glaciers, ice shelves, snow, icebergs, and arctic climatology


Interconnected spheres

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

    • Turbidity => impacts water plants/animals


Event sphere

Event <=> Sphere

  • Causes & Effects

  • Interactions

  • Event <=>Sphere

  • Sphere<=>Sphere
