Ost plate tectonics and earth's interior
WebThe concept of plate tectonics was formulated in the 1960s. According to the theory, Earth has a rigid outer layer, known as the lithosphere, which is typically about 60 miles (100 kilometers) thick. The lithosphere overlies a softer layer of molten rock called the asthenosphere. The lithosphere is broken up into about a dozen large plates and ...

WebCrustal Plate Boundaries. (Courtesy NGDC) Plate tectonics involves the formation, lateral movement, interaction, and destruction of the lithospheric plates. Much of Earth's internal heat is relieved through this process and many of Earth's large structural and topographic features are consequently formed. Web1.
