  • The theory of Plate Tectonics
  • How Plates are able to move
  • What happens at the margins of Plates
  • The position of Ireland in relation to plate boundaries now and in the past

    The plates have not always been in their current locations. The Earth did not always have seven continents, it was a super-continent called Pangaea, which was surrounded by one ocean.

    About 200 million years ago Pangaea began to break up and form plates, as they moved so did the continents, this process is known as continental drift.

    Scientists believe in another 250 million years they will join together to form a new different super-continent. ]]>     2020-09-13 17:07:06 UTC https://padlet.com/seannain/2ptztkpx62v0gsqt/wish/742002631     Plate Tectonics seannain https://padlet.com/seannain/2ptztkpx62v0gsqt/wish/742004181 The lithosphere is divided into large, rigid sections called plates.  Plates float on the Athenosphere, the semi-molten section of the mantle. 
    The movement of these plates and the activities that result from it is called plate tectonics.

    The Theory of plate tectonics combines two earlier ideas:

    1. continental drift
    2. sea-floor spreading
