Study Notes
Types of Plate Boundaries
- Three main types of plate boundaries: Divergent, Convergent, and Transform fault.
Divergent Plate Boundary
- Forces pull apart; plates move away from each other.
- May involve two oceanic plates or two continental plates.
- Common geologic features include rift valleys and mid-ocean ridges.
- Example: Red Sea.
Convergent Plate Boundary
- Forces push toward each other; plates collide.
- Interaction can include oceanic to oceanic, oceanic to continental, or continental to continental crusts.
- Results in formations like mountains, volcanoes, and island arcs.
- Example: Himalayas formed by continental collision.
Transform Fault Boundary
- Forces slide past each other, moving in opposite directions.
- Typically involves continental crusts.
- Characterized by zigzag margins and creating earthquakes.
- Example: San Andreas Fault.
Geologic Events and Features
- All types of plate boundaries produce geologic events, primarily earthquakes.
- Each boundary type exhibits distinct features depending on the interaction of plates involved.
Application Activities
- Create models of plate boundaries using soap, sand, clay, and Graham/Oreo.
- Activities include identifying types of boundaries and their corresponding crust interactions.
Assessment Focus
- Geologic features associated with each boundary type.
- Identification of examples such as divergent boundaries (e.g., Red Sea) and features formed by convergent boundaries (e.g., mountain ranges).
- Knowledge of where certain boundary types are commonly located, such as transform boundaries predominantly found on continental crust.
Earthquake and Island Formation
- Philippines' island formation mainly due to convergent plate interactions.
- Areas like Palawan have less earthquake activity due to location relative to fault lines.
Directions of Forces
- Divergent: Away from each other.
- Convergent: Toward each other.
- Transform: Sliding past one another.
Visual Representations
- Illustrate interactions at each boundary type and the direction of forces using arrows for understanding movements and resulting features.
