1. Unit 3: Geological Oceanography

2. Formation of the Earth and Oceans

3. Density Stratification
The process by which matter became layered according to density during Earth’s formation
Heavier matter near the center and lighter material closer to the outside

4. Atmosphere Formation
Earth cooled, crust solidified, gases released by volcanic activity accumulated
Earth’s Atmosphere…
Water vapor, carbon dioxide, and nitrogen

5. Origin of the Ocean
As the Earth cooled, water accumulated forming bodies of water
Eventually, the oceans created atmospheric changes required for terrestrial life to form

6. Earth’s Structure
Draw and label a diagram of the structure of the Earth (make sure the layers are proportional)
Color each layer a different color
Label the width of each layer (or the distance of each layer from the Earth’s surface)
Write a description of each layer
