Constructive Margins:

  • Occur when two plates are moving apart
  • The mantle is under pressure, when they move apart the pressure is realsed at the margin
  • The pressure can cause the mantle to melt, forming magma
  • The magma is less dense so rises and can form a Volcano
  • The plates do not move apart at the same time, this causes pressure to build as well…
