Plate Boundaries Flashcards

1
Q

Divergent plate boundary

AKA constructive plate boundary

A
  • Convection currents pull tectonic plates apart
  • New crust is created
  • Magma can reach the surface through cracks and cause volcanic eruptions

Q

Conservative plate boundary

AKA transform plate boundary

  • Where plates are moving side by side
  • No crust is created or destroyed
  • Stress builds up on faults, and a sudden release creates earthquakes

Q

Convergent plate boundary

AKA destructive plate boundary

A
  • Where an oceanic and continental plate are moving towards each other
  • Pressure builds up and volcanic eruptions occur
  • Earthquakes also occur because of subduction

Q

Collision plate boundary

A
  • Where two continental plates are moving towards each other
  • They crash and crumple upwards to form fold mountains
  • Earthquakes occur due to movement and pressure
