- Theoretical Frameworks and Plate Movements
- Different Types of Crust
- Oceanic Crust
- Thinner
- Underlines ocean basins
- Continental Crust
- Thicker
- Underlies the continents
- Oceanic Crust
- Mantle
- It has a temperature gradient
- The highest temperatures occur where the mantle material is in contact with the heat-producing core
- Rocks in the upper mantle are cool and brittle
- Brittle enough to break under stress and produce earthquakes
- Rocks in the lower mantle are hot and plastic
- Flow when subjected to force
- The Benioff Zone and Subduction Processes
- Benioff Zone
- Area of seismicity corresponding with the slab being thrust downwards
- The site of deep-focused earthquakes
- Benioff Zone
