Plate Tectonics
21
Continental Drift: The theory that the earth's plates are in constant motion
Convection: The heating and movement of molten material
Mantle: The layer outside of the core
Core: The innermost part of the earth
Subduction: Where one plate moves under another
Convergent: Two plates that are moving together
Divergent: Where two plates move away from each other
Transform: Where two plates slide past each other
Fault: A crack in the crust
Sea Floor Spreading: Divergent ocean plates let out magma, which turns into new land
Volcano: A crustal feature that is similar to a mountain, but has lava coming out of it
Ring of Fire: An area along the Pacific plate with numerous volcanoes
North American: The plate we live on
Harry Hess: The man who discovered sea floor spreading
Trench: Crustal feature where one oceanic plate subducts under another
Rift Zone: Area between underwater mountain ranges
lava: Magma that has reached above ground
geology: The study of the earth
lithosphere: The crust and the upper part of the mantle
mountain: Where two convergent plates on land rise up (crustal feature)
Pangaea: A supercontinent made of all the continents
