Tectonic hazards

• What are the two tectonic hazards?

  Volcanoes and earthquakes
• How do tectonic plates move?

  Ridge push and slab pull
• What is ridge push?

  When plates are moving away from each other at a constructive plate margin, magma pushes up through the gap, creating a ridge that solidifies into rock
• What is slab push?

  When one plate is subducted under another plate at a destructive plate boundary, underneath the plate in the subduction zone, increased pressure causes the plate the fall quickly and cause earthquakes and volcanoes
