Dynamic Earth

Divergent Boundary


 * The magma rises and pushes plates apart
 * Mountains and Volcanoes rise from the seam ( Great River Valley In Africa is an example)
 * Causes sea floor spreading and volcanic activity
 * An example of Divergent Boundary is between Africa Plate and the Arabian Plate in the Red Sea(African and Arabian Plates diverging)
 * Two Current examples are Mid- Atlantic and East Pacific Ridge( Divergent Boundary and transform Faults)



Convergent Boundary


 * Convergent Boundary is when Plates collide or dive under or above each other
 * These types of collision can cause underground volcanoes
 * Current examples are Islands of Indonesia, Mariana Island, Western Coast of South America, and Himalayas
 * Much earthquake activity in Convergent Boundaries(Mount Shasta is and example in California)
 * Plates colliding or diving cause disturbance and much action in the earth
 * Subduction Boundary
 * Oceanic Plates diving beneath another plate( Indonesian Island of Krakatau formed near a Subduction Boundary)
 * Collision Boundary
 * Two continents colliding and welding into a single( Himalayas is an example of Collision Boundary)[[image:Convergentplateboundary1.jpg width="293" height="230"]]

Transform Boundary

Parker, John. "National Geographic." //Science and Spaces//. National Geographic Society, 1996-2009. Web. 11 Nov. 2009. [].
 * Transform is two plates grinding against each other
 * Transform Boundaries do not produce spectacular features
 * Halting motion triggers large eruptions or earthquakes( 1906 Halting motion caused large Earthquake in San Francisco)
 * San Andreas Fault is an example of Transform Boundary in Taft California
 * Fracture zones are along mid-ocean ridges
