    This animated video shows the movement of the tectonic plates1 that make up the Earth’s crust2.

    Starting 600 million years ago, watch continents3 form and break apart as the plates move. Pangaea the supercontinent, split up at about 220 million years ago into Laurasia and Gondwana4 both of which broke up again. Gondwana which comprised Australia, Antarctica (including New Zealand), India, Africa and South America started breaking up about 150 million years ago. Australia departed from the Antarctica group at around 50 million years and around 35 million years ago South America moved away leaving Antarctica to move towards its current position.

    Transcript

    600 million years ago, all the land on Earth was part of one supercontinent – Pangaea.

    Heat5 from under the crust causes the land to move. Pangaea broke up into Laurasia and Gondwana.

    Laurasia formed the northern continents while Gondwana broke up into the southern, including Africa and Australia.

    The land continues to move about a centimetre per year. The spaces between continents filled with water, making oceans and seas.

    New Zealand was formed by the Australian and Pacific plates sliding together. Where they join is now the Southern Alps.

    1. tectonic plate: One of several large sections of the Earth’s crust. The Earth’s surface consists of six big tectonic plates and several smaller ones.
    2. crust: The outermost layer of the Earth. Estimated to be between 5–50 km thick. Made of solid rock of all types (metamorphic, igneous and sedimentary).
    3. continent: In geology, any of the main continuous expanses of continental crust on the Earth. Africa, Antarctica, Asia, Australia, Europe, North America and South America are recognised as continents, but this is based on historical and cultural attributes rather than geological attributes.
    4. Gondwana: A continent (large landmass) in the Southern Hemisphere that eventually separated to form South America, Africa, Antarctica, Australia and New Zealand. Gondwana separated from the supercontinent of Pangaea at the end of the Paleozoic Era and broke up into the current continents in the middle of the Mesozoic Era.
    5. heat energy (heat): Heat energy: the transfer of energy in materials from the random movement of the particles in that material. The greater the random movement of particles the more heat energy the material has. Temperature is a measure of the heat energy of a material.
      Heat: the flow of energy from a warm object to a cooler object.
