plate tectonics voc


theory of continental Continental drift is the movement of the Earth's continents relative to each other by appearing to drift across the ocean bed
pangea (plate tectonics) a hypothetical continent including all the landmass
inner core its innermost part, is a primarily solid ball with a radius of about 1,220 km
outer core The outer core of the Earth is a liquid layer about 2,266 km thick
mantle The mantle is a part of a terrestrial planet or other rocky body large enough to have differentiation by density
crust the crust is the outermost solid shell of the earth
lithosphere the rigid outer part of the earth, consisting of the crust and upper mantle.
atsthenosphere the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
continental crust the relatively thick part of the earth's crust that forms the large landmasses
oceanic crust the relatively thin part of the earth's crust that underlies the ocean basins
divergent boundery In plate tectonics, a divergent boundary or divergent plate boundary
convergent boundery an actively deforming region where two tectonic plates or fragments of lithosphere move toward one another and collide
transform boundery a type of fault whose relative motion is predominantly horizontal in either sinistral or dextral direction
