Study Notes
Plate Boundaries
- Divergent Boundary: Plates move apart; examples include continental-continental rifts (forming rift valleys) and oceanic-oceanic mid-ocean ridges (resulting in seafloor spreading).
-
Convergent Boundary: Plates collide; types include:
- Continental-oceanic: denser oceanic plate subducts beneath continental plate, forming a trench and a continental volcanic arc.
- Oceanic-oceanic: one oceanic plate subducts under another, creating a volcanic island arc and a trench.
- Continental-continental: both plates buckle and uplift, forming mountain ranges.
- Transform Boundary: Plates slide past each other horizontally, often resulting in faults and earthquakes.
