Pangaea
large super continent that was exsisted
tectonic plates
broken sections of the lithosphere that move along the asthenosphere
Plate Tectonics
the theory that the Earth is divided into sections that move creating volcanoes, earthquakes, mountains, and trenches
continental drift
the theory that the continents have moved over time
convergent boundary
the edge of two tectonics plates where those plate move towards each other
transform boundary
the edge of two tectonics plates where those plates slide past one another
divergent boundary
the edge of two tectonics plates where those plates pull apart from one another
Mid Ocean Ridge
divergent boundary in the Atlantic Ocean where new crust is created
sea floor spreading
process that explain how crust in the middle of the ocean is younger because plates move apart
folded mountains
created when two continental plates of similar mass push together
volcanoes
created when one plate is forced under another into a subduction zone and magma build up burst though plates over time
earthquakes
occur as plates slide and tension gets released
