Why do plates move?

Plates move due to convection currents in the mantle.

How are Oceanic plates different to Continental pl

Oceanic plates are denser, younger and able to subduct. Whereas, Continental plates are lighter, older, and are not able to subduct.

Subduction is wear one edge of one crustal plate is forced below the edge of another.

Constuctive

This is when two plates move apart from each other. New land is made.

This mainly occurs under oceans.

Conservative

This is when two plates slide past each other. Pressure builds up until one plate jerks past another. No land is created or destroyed. 

4 of 5

Destructive

This is when two plates move towards each other. The denser (oceanic) plates subduct below the lighter continental plates. The energy between them builds up and may be released as an earthquake.

Usually the Oceanic plate moves under the Continental Plate because the Oceanic plate is denser, this causes volcano eruptions and earthquakes, it also forms fold mountains
