Plate Boundaries and Crustal FormationsFlip
Notes
2
DIVERGENT BOUNDARIES

• Occurs when two plates are DIVIDING or pulling
  apart.
• Crustal Feature Mid-Ocean Ridge or Rift Valley
• (Example Mid-Atlantic Ridge)
• Boundary 1) Oceanic/Oceanic
• 2) Continental/Continental

3
CONVERGENT BOUNDARIES

• Occurs when two plates are COLLIDING or moving
  toward one another.
• Crustal Feature Mountains
• (Example Himalayan Mountain Range)
• Boundary Continental/Continental

4
SUBDUCTION ZONES

• Occurs at a convergent boundary. Since these two
  plates have different densities, the denser plate
  subducts under the less dense plate.
• Crustal Feature Volcanic Mountain and Trench
• (Example Andes Volcanic Mountains)
• Boundary Oceanic/Continental

5
TRANSFORM BOUNDARIES

• Occurs when two plates SLIDE PAST one another,
  causing a shearing motion which breaks down the
  edges of the plates.
• Crustal Feature Faults, which build up friction
  and cause earthquakes!
• (Example San Andres Fault in California)
• Boundary Continental/Continental

6
HOT SPOTS

• Hot Spots are volcanic regions thought to be
  above extremely hot areas of the mantle. These
  hot spots can create volcanic mountain chains and
  islands (like the Hawaiian islands).
