The movement is caused by the convection currents that roll over in the upper zone of the mantle. Tropical areas never had glaciers, so lush, warm-weather plants thrived all during the Quaternary Period. For example, Pangaeas large mass insulated the mantle underneath, causing mantle flows that triggered the initial breakup of the supercontinent. Laurasia was made of the present day continents of North America (Greenland), Europe, and Asia. There is no reason why the crust that forms the continents could not again come together.
