Conservative (transform)

  • The 2 plate boundaries ether rub against or together each other.
  • This causes pressure to build up and with a jolt releases the energy (seismic waves), causing an earthquake.
  • This could be made worse by the rock type and if the focus is near the top of the earth then more energy comes out.
  • Example: San Andreas Fault- San Francisco.

  • The two plates collide together and go up creating a fold up montain.
  • Example: Mount Everest- Himalayas

Constructive (divergent)


  • The two plates move apart so a gap is created.
  • Magma rises into the gap and creates a volcano, magma escapes easily causing an eruption.
  • No force.New land is made. Example: Mid-Atlantic Ridge.

Destructive (convergent)

  • Oceanic crust always goes under the continental plate (subduction).
  • Oceanic crust is melted due to friction by movement.
  • Magma rises causing gaps in the contintal plate so a volcano forms.
  • Examples: Ring of Fire- Pacific Ocean
