Plate Tectonics

Earth’s lithosphere is divided into a series of major and minor mobile (in motion) plates.

1.Plates move at rates of a few cm per year.

2.Plates may be composed of continental and/or oceanic lithosphere.

3.Plate movement is believed to be caused by the convection currents in the asthenosphere

4.The movement of plates explains earthquakes and volcanic activity
