Science tectonic plates Flashcards
Reading where Two tectonic plates are moving apart
Divergent boundary
Continental crust begins to separate, the stretched crust forms a long narrow depression
rift valley
process in which the weight of the uplifted ridge will push the oceanic plate toward
ridge push
region where two tectonic plates are moving toward each other
convergent boundary
process in which the denser oceanic plate sinks beneath the continental crust
Subduction
supercontinent that broke apart 200 million years ago due to continent drift
pangea
region where two plates horizontally slide past each other
transform boundary
process where the weight of the subduction plate pulls the trailing slab into the subduction zone
slab pull
________ states that continents can drift apart from one another and have done so in the past.
Continental drift
Similar rock types and _______ located across the ocean are clues that these
land masses were once connected.
Fossils
Oceanic plates are ________ than continental plates so when they collide the oceanic plate will sink under the continental plate.
denser
The San Andres Fault is located at ___________ boundary.
Transform
The process of _________ creates new oceanic lithosphere as older materials are pulled away.
Seafloor spreading
