Drift and Tectonics

Land Beneath Our Feet #2

continental drift Wegner's theory that Earth's continents were once joined in a single landmass and gradually moved apart
Pangaea Wegner's name for the supercontinent
mid-ocean ridge underwater mountain ranges
convection energy transfer by the movement of a material
convection currents sinking and rising motion that occurs through the transfer of heat energy
theory of plate tectonics theory that states that Earth's lithosphere is made up of huge plates that move over the surface of the Earth
divergent boundary occurs where plates move/pull apart
convergent boundary occurs where plates move/push together
transform boundary occurs where plates scrape/slide by one another
rift valley happens where ridges continue to widen and create a gap and molten material rises to build new crust
magnetic reversal where the North and South Poles switch position
hot spots where heated rock rises in plumes or thin columns from the mantle
subduction one plate sinks beneath another
continental-continental collision 2 continental plates carrying continental crust push together forming mountains
oceanic-oceanic subduction 2 oceanic plates come together as one sinks beneath the other due to density (forms ocean trenches and island arcs)
oceanic-continental subduction when oceanic crust sinks under continental crust (forms deep ocean trenches and coastal mountains)
