Earth Science: Earth History
Terms in this set (11)
The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations
the formation of new areas of oceanic crust, which occurs through the upwelling of magma at mid ocean ridges and its subsequent outward movement on either side.
super continent consisting of all known continents fitting together at one point in the Earth's history
the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another
part of outermost compositional layer of earth. Usually made of granite (mostly quartz and feldspar minerals)
the portion of Earth's crust that is usually below the oceans and not associated with continental areas, thinner and higher in density
Geologist considered to be one of the "founding fathers" of the unifying theory of plate tectonics because his Sea-floor Spreading Theory and evidence supported the Plate Tectonic Theory
proposed the theory of continental drift that states that all land on the earth was once a single mass but eventually broke apart from one another and drifted away
a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle
The theory that the earth is broken into plates and are in motion due to convection currents in the asthenosphere (upper mantle)
Mid Ocean Ridge
An underwater moutain chain where new ocean floor is formed
