Plate Tectonics Outline
Earth Layers
- Inner Core (Solid)
- Outer Core (Liquid)
- Mantle
- Mesosphere (Solid)
- Asthenosphere (Plastic)
- Lithosphere (Solid)
- Crust
Earth Spheres
- Geosphere (Rock)
- Biosphere (Life)

- Atmosphere (Air)
Heat Transfer in the Earth
- Radiation
- Conduction
- Convection
Continental Drift
- Evidences
- Shape of the continents
- Fossils
- Folded Mountains
- Glacial Deposits
- Coal
- Did not have a mechanism. This meant Wegener could not explain WHAT caused the continents to move.
Seafloor Spreading
- WWII Sonar
- M.O.R.
- Magnetic Striping
- Age increases as you go farther from the M.O.R.
- Could not explain what happened to old crust
Plate Tectonics
- Types of Boundaries
- Divergent
- Convergent
- Ocean to Continent Subduction
- Ocean to Ocean Subduction
- Transform
