Study Notes
Destructive Plate Boundaries
- Convection currents in the Earth's mantle cause plates to collide at convergent boundaries.
- Oceanic plates collide, the denser plate subducts beneath the less dense.
- Subduction creates an arc-shaped ocean trench.
- Fluids and gases released during subduction cause melting and magma formation.
- Magma rises, creating explosive volcanic eruptions.
- Volcanic island arcs form parallel to the trench (e.g., Japanese islands).
- Oceanic crust is destroyed where oceanic and continental plates collide.
- Volcanic mountain ranges (e.g., Andes) form parallel to subduction zones.
- Fold mountains form due to buckling of continental crust.
- Powerful earthquakes occur due to rocks locking and releasing stress.
- Continental plates colliding cause no crust destruction, only buckling and mountain formation (e.g., Alps).
- Earthquakes are generated when convection currents force plates to move suddenly.
