a scientific theory that describes the large scale motions of the Earth's plates which make up the lithosphere. These plates rest on the asthenosphere.

 It is believed that tectonic plates are moved by several different forces: ◦ Rotation of the earth ◦ Tidal forces of sun & moon ◦ Gravitational pull ◦ Convection cell

Developed the theory of Pangea & Continental Drift. Alfred Lothar Wegener

Direction of plate drift

 Convergent  Divergent  Transform Tectonic Plate Motion

There are 3 types of convergent boundaries, all 3 cause earthquakes.  Oceanic>Continental ◦ Volcanoes ◦ Oceanic trenches  Oceanic>Oceanic ◦ Tsunamis ◦ Volcanoes ◦ Island arcs  Continental>Continental ◦ Mountain building

There are 2 types of divergent boundaries.  Sea Floor Spreading ◦ Oceanic Ridges  Continental Rift ◦ Rift Vallies

three plates are pulling away from one another: the Arabian Plate, and the two parts of the African Plate(the Nubian and the Somalian) Rifting earth of Ethiopia

A transform boundary is just that, a transform boundary.  Transform boundaries can have jagged edges that get caught on each other, when this happens massive pressure builds up which releases in an: ◦ Earthquake.
