Plate Tectonics <br />The theory that proposes that Earth’s outer shell consists of individual plates that interact in various ways and thereby produce earthquakes, volcanoes, mountains, and the crust itself.<br />
Plate<br />One of numerous rigid sections of the lithosphere that moves as a unit over the material of the asthenosphere.<br />
Divergent Boundary <br />A region where the rigid plates are moving apart, typified by the oceanic ridges. <br />
Covergent Boundary <br />A boundary in which two plates moves together.<br />
Transform Fault Boundary<br />A boundary in which two plates slide past each other without creating or destroying lithosphere.<br />
Key Concept<br />What is the theory of plate tectonics?<br />According to the theory of plate tectonics, the uppermost mantle, along with the overlaying crust, behaves as a strong, rigid layer. This layer is known as the lithosphere.<br />
Key Concept<br />What are lithospheric plates?<br />They are plates within the lithosphere that are continually moving and changes shape/size.<br />
Key Concept<br />What are the three types of plate boundaries? <br />The three types of boundaries are convergent, divergent, and transform fault boundaries. <br />
