A. The Solid Earth

B. The Hydrosphere - our distinguishing character

C. The Atmosphere

D.The Biosphere

Is the Earth a closed system?

the parts of the Earth system are linked => events that occur in one system can affect the others

II. Solid Earth Processes => Internal
Internal Structure = layered

A. The Layered Earth - Properties

1. Crust = brittle, rocky

2. Mantle = plastic

3. Core = Liquid Iron
and Nickel outer part
Solid inner part...
 

Outer Core = Internal Heat
  Engine

B. Mantle Convection
 1. Heating mantle from below causes
 convection…...

2. Convection in mantle causes crust to
 move and break into plates
 

Moving Plates = Plate Tectonics

the most dynamic spots on Earth = Plate Boundaries

C. Plate Boundaries
Divergent
Convergent
Transform

III. Surface Processes
Powered by the Sun and Other

EX: the Hydrologic Cycle
 Sculpts surface and breaks down Earth Materials
