1 What properties distinguish the following zones of Earth's interior? Elaborate.continental crust, oceanic crust, and mantlelithosphere, asthenosphere, and mesospherelow velocity zone (LVZ), transition zone, and D″ layercore, outer core, and inner core

2 Detail the processes by which oceanic crust is created and grows through time and contrast these with the processes by which it shrinks and is “destroyed.”

3 Explain why the age of oceanic crust generally increases systematically away from the ridge system axis in both directions and the major reasons why there are so many local exceptions to this rule.

4 Describe the three major types of plate boundaries and the features that are associated with and produced by each.

5 Explain how transform faults between two ridge segments form and how, over time, they can generate long fracture zones in oceanic crust. In addition, contrast the earthquake activity on transforms with that on (the external portions of) fracture zones and explain the major reason for this contrast.
