Best Answer: Divergent Plate Boundaries - where the earth is cracked open under the ocean and new lava comes up and hardens forming new ocean crust. http://www.cotf.edu/ete/modules/msese/ea...
1 The lithosphere is composed of the crust, and some of the upper mantle. 2  Mature oceanic plate is approximately 80-100 km thick, of which, the upper 5-7 km is oceanic crust. 3  Continental plate is somewhat thicker, perhaps 150-200 km thick, and includes continental crust which varies from 5 to 70 km in thickness. At other convergent boundaries, oceanic plate meets other oceanic plate. 2  This results in an oceanic trench and a chain of volcanic islands known as an island arc. Japan, the Philippines and the Aleutians are examples of island arcs. 3  At some convergent boundaries, two continents collide.
