I think Science Vocabulary for 6th grade
I believe that this flashcard set was meant for 6th grade vocabulary. I'm not sure cause it wasnt saved and I just restored it. If u know for sure, then name it correctly. Thanks!

A plate boundary where two plates move past each other in opposite directions.
An undersea mountain chain where new ocean floor is produced; a divergent plate boundary.
deep ocean trench
A deep valley along the ocean floor where oceanic crust slowly sinks back into the mantle.
The theory that pieces of Earth's lithospheric plates are in constant motion, driven by convection currents in the mantle.
A section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental crust and oceanic crust.
