  1. In general, mountain-building often occurs near what type of plate boundary?
    Convergent plate boundaries
  2. Define orogenesis
    Orogenesis: Processes that collectively produce a mountain belt
  3. Describe the 4 processes/settings that produce mountain belts.

    Volcanic Activity at Subduction Zones
    • o/o: volcanic island arc
    • o/c: continental volcanic arc

    Forearc region(Compressional Stress) - area between trench and volcanic arc: overlaying plate advances faster than the trench "rolls back"

    Backarc region(Tensional Stress) - located on the opposite side of the arc: slab suction pulls upper plate toward the trench
