Alfred WegenerFirst proposed the hypothesis of continental drift, based on fossil evidence, geographic similarities and the puzzle like shapes of continents.
AsthenosphereThe soft layer of the mantle on which the lithosphere floats.
ConductionThe transfer of heat by direct contact of particles of matter.
Continental driftThe hypothesis that the continents slowly move across the Earth's surface.
ConvectionThe trans of heat by the movements of a heated fluid.
Convection currentThem movement of fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another.
Convergent BoundaryA plate boundary where two plates move toward each other.
Divergent BoundaryA plate boundary where two plates move away each other.
GeologyThe study of rocks, the Earth, and the forces that shape the Earth.
Harry HessFirst proposed the hypothesis that oceanic crust moved, (discovered sea-floor spreading) which would explain how continents could move. This helped to support Wegener's hypothesis of continental drift.
J.Tuzo WilsonScientist who recognized the significance of crack in the Earth's crust as "plate" boundaries, and put together the Theory of PLATE TECTONICS from his observations, Wegener's observations / hypothesis, and Hess's data on sea floor spreading.
LithosphereA rigid layer made up of the uppermost part of the mantle and the crust.
PangaeaThe name of the single landmass that broke apart 200 million years ago.
PlateA section of the lithosphere that slowly moves over the asthenosphere carrying pieces of oceanic and/or continental crust.
Plate TectonicsThe theory that pieces of the Earth's lithosphere are in constant motion, driven by convection currents in the mantle.
RadiationThe transfer of energy through empty space or air.
SubductionThe process by which oceanic crust sinks into a deep-ocean trench (under continental crust) and back into the mantle at a convergent plate boundary.
Transform BoundaryA plate boundary where two plates move past each other in opposite directions.
