4. Tectonic Plate Boundaries

5. Sea floor Sea-floor spreading creates new oceanic lithosphere at mid- ocean ridges.

6. Pangaea

7. Structure of the earth

8. Vocabulary Review Asthenosphere- the soft layer of the mantle on which pieces of the lithosphere move Plate tectonics- the theory that the earths lithosphere is divided into tectonic plates that move around on top of the asthensphee Folding-the bending of rock layers due to stress in the earths crust Convergent boundary-the boundary between two colliding tectonic plates

9. Vocabulary Review Sea-floor spreading- the process by which new oceanic lithosphere is created at mid-ocean ridges as older materials are pulled away from the ridge. Crust- the thin, outermost layer of the earth, or the uppermost part of the lithosphere. Seduction zone-the region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plate

10. Vocabulary Review Stress- the amount of force per unit area that is put on a given material. Tension- the type of stress that occurs when forces act to stretch an object. Reverse fault- a fault in which the hanging wall moves up relative to the footwall.
