Document Summary
Chapter 1, p. 16-17; chapter 12, p. 270-290 earth: an introduction to. Plate tectonics characterized: is driven by earth"s internal heat, and is essentially a means of conveying heat from the interior to the exterior, cooling the earth. Neither radiation of heat nor conduction of heat through rocks is effective (rocks are good thermal insulators), so the best means to move heat through rocks is by convection, in the solid state. Earth"s core probably has convection cells in the liquid outer core, established as core materials cool, solidify, and sink, replaced by rising heated material; this mechanism is responsible for the complexity of. We observe that certain topographic and geologic features and processes. Eas 210 characterize particular types of plate boundaries, defined by the combination of the sense of motion at the boundary, and the type of crust on the two plates at a particular boundary. Rift valley; normal faults, horst & graben terrain.
