The Structure of the Earth and Plate Tectonics. Structure of the Earth. The Earth is made up of 3 main layers: Core; Mantle; Crust. Inner core. Outer core. Mantle. Heated soup rises to the surface, spreads and begins to cool, and then sinks back to the bottom of the pot where it is reheated and rises again. Plate tectonics.
Plate Tectonics. Geological and geophysical evidence of plates and plate dynamics. Earth's lithosphere consist of relatively rigid plates that move independently. Plate Tectonics. What is Plate Tectonics. The Earth is broken into large Plates. The size and position of Plates change. Plate edges colliding - geologic activity. Plate Tectonics. Continental Drift.
