Plate tectonics Asthenosphere Lithosphere Mantle Continental Crust Oceanic Crust Pangaea Convergent Divergent Transform Subduction Collision Convection Continental drift Sea floor spreading Continental rift Earthquake Tsunami Volcanic activity Oceanic trench Oceanic ridge Rift valley Mountain building Island arc
3
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.
5
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
6
Developed the theory of Pangea & Continental Drift. Alfred Lothar Wegener
9
Direction of plate drift
10
Convergent Divergent Transform Tectonic Plate Motion
11
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
18
There are 2 types of divergent boundaries. Sea Floor Spreading ◦ Oceanic Ridges Continental Rift ◦ Rift Vallies
22
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
23
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.
