Study Notes

Crust Characteristics

  • Oceanic crust is thinner than continental crust.
  • Oceanic crust is denser than continental crust.

Plate Boundaries

  • Convergent plate boundaries are formed at a destructive plate boundary, where two plates move towards each other.
  • The type of geologic process that occurs along a convergent plate boundary is determined by the nature of the plates involved (oceanic-oceanic, oceanic-continental, or continental-continental).

Geologic Processes

  • Possible geologic processes that can occur along a convergent plate boundary include subduction, collision, and volcanic island arc formation.
  • Continental rifting is NOT a possible geologic process that can occur along a convergent plate boundary.
