Convection

• Energy transferred by the movement of a substance.

3
Subduction

• Subduction occurs at converging plate boundaries.
• One plate slides under the other and is recycled
  into the mantle.
• Typically an oceanic plate slides under a
  continental plate. Earthquakes and volcanoes can
  occur along this zone.
