PLATE TECTONICS A PRIMER

PLATE TECTONICS Heat flowing from the interior of the earth through the mantle and lithosphere to the surface is the engine that causes major and minor portions of the Earth’s crust (i.e., tectonic plates) to slowly converge, diverge, or slide past each other over time. The relative movement of plates causes compression, tension, or shear, which causes faulting and earthquakes.

HEAT FLOW IS GREATER AT PLATE BOUNDARIES

TECTONIC PLATES TWO EARTH DAYS AGO

TECTONIC PLATES TODAY

PLATE TECTONICS Plate boundaries are defined by seismic activity (i.e., seismicity) . Plate boundaries are often marked by prominent fault zones that may in some cases cause notable surface faulting.

Plate Movement Causes Three Primary Kinds Of Faulting Strike-Slip Reverse Three types of faults Form depending on type of plate motion and complex reaction of earth’s lithospheric blocks Strike-slip Normal Thrust Normal
