|
|
Term
which of the following results when divergence occurs between two oceanic plates? |
|
Definition
divergence creates new seafloor. divergence causes ocean ridges and raft valley |
|
|
Term
the Himalayas in South Asia are an example of what type of plate of boundary? |
|
Definition
convergent boundary and result of continental-continental collisions. |
|

Term
according to the property of palemagnetism what happened |
|
Definition
rock formed millions of years ago thus show the location of the magnetic poles at the time of their formation |
|
|
Term
how does the age of a seafloor sediments change with increasing distance from the ridge? |
|
Definition
when the oldest sediment from each drill site was plotted against it's distance from the ridge crest, it was revealed that the age of the sediment increased with increasing distance from the ridge. |

Term
the thermal convection that drives plate motion is caused by |
|
Definition
unequal distribution earth's heat |
|
|
Term
|
Definition
divergent- also called spreading center occurs when two plates moves on apart. this process results in upwelling of materials from the mantle to create new seafloor. hot spots- concentration of heat in the mantle capable of producing magma , which rises to earth's surface. the pacific plate moves over a hot spot,producing the Hawaiian island. lithosphere-rigid outer layer of earth ,including the crust an upper mantle Pangaea- the proposed Super continent that 200 MY began break apart an form the present landmasses |
