QuestionAnswer
Asthenosphere Plastic like layer of Earth on which the lithospheric plates float and move around.
Continental Drift Hypothesis that continents were once connected in a single large land mass that broke apart about 200 mil. years ago.
Convection Current Current in Earth's mantle that transfers heat in Earth inteior and is the driving force for plate tectionics.
Lithosphere Rigid layer of Earth about 100km thick, made of the crust and part of the upper mantle.
Pangaea largte ancient landmass that was composed of all the continents joined together.
Plate a large section of Earth's oceanic or continental crust and rigid upper mantle that moves around on the asthenosphere.
Plate Tectonics Theory that Earth's crust and upper mantle are broken into plates that float and move around on a plasticlike layer of the mantle.
Seafloor spreading Theory that new seafloor is formed when magma is forced upward toward the surface at a mid ocean ridge.
Who theory was seafloor spreading? Hess
Who theory was continental drift? Wegener
Subduction Zone Area where an oceanic plate goes down into the mantle.
Divergent Boundary Boundary between two plates that are moving apart.
Convergent Boundary Boundary between two plates that are moving together.
Transform Boundary Plate boundary that occurs when two plates slide past one another.
Magneticometer Sensing device that detects magnetic fields, helping to confirm seafloor spreading.
Mantle Largest layer of Earht's surface, composed mostly of silicon, oxygen, magnesium, and iron
Crust Outer most layer of Earth's surface.
Convergent boundarys form deep sea trenches, volcanic islands, and colcanic mountains.
Divergent boundarys form Mid ocean rifts, rift vally
