Tectonic Plates.

Tectonic Plates.

1. Huge slabs of crust.

2. Plate boundaries are where the plates meet.

3. Convergent.

   • Subduction.
     • Oceanic meet continental plates.
       • Volcanoes are formed.
       • Causes earthquake.
   • Collision zone.
     • Two continental plates meet each other.
       • Forms mountains.
         • Himalayas.

4. Divergent or Constructive.

   • Two plates move away from each other.
     • Causes shield volcanoes from rising magma
       • North American plate moving away from Eurasian plate.
         • Creating Mid-Atlantic and Iceland through volcanic activity.

5. Conservative.

   • Two slates just slide past each other.
     • Causes earthquakes.
       • San Andreas Fault.
