DRA quiz Flashcards
the theory that Earth is divided into plates that move around
Plate tectonics
the place where tectonic plates touch
tectonic boundary
not a type of tectonic plate boundary
fault-block boundary
3 ways that tectonic plates can move relative to each other
collide, separate, and slide
2 plates with continental crust collide, what happens to the continental crust
buckle and thicken, which pushes continental crust upward sometimes creates mountains
boundary form when tectonic plates collide
convergent boundary
boundary formed when tectonic plates separate
divergent boundary
boundary formed when tectonic plates slide past horzontally
transform boundary
which type of boundary produces strike slip faults
transform boundaries
type of boundary that produces earthquakes
transform boundaries
when rock is heated it becomes less dense and tends to
rise
when rock cools, it becomes more dense and tends to
sink below surface
density changes in the asthenosphere are cause by the flow of the ————– energy from deep within the earth
thermal
plate motion due to higher densities
slab pull
plate motion due to gravity
ridge push
