When a convergent plate boundary collides but one plate is pushed underneath another. This happens with continental-oceanic convergent plates
subduction
400
Where is the oldest ocean crust/rock
Near the trenches

What was the piece of evidence that helped proved the theory of continental drift?
Plate tectonics/seafloor spreading was the force moving the continents.

This is a transform fault in California that will eventually put Los Angeles in the ocean
San Andreas Fault
500
a geologic feature or landform that's created when two tectonic plates move away from each other in the middle of the ocean.
Ridge
500
What happens to the ocean crust once it is subducted or pushed under continental crust? (subduction)
It is recycled by the magma underneath the tectonic plates
500
What is some climate evidence that the continents were once together and drifted apart? 
Glossopteris and Lystrosaurus both found in Antarctica. Antarctica is a cold climate so it must've been in a different location on Earth that had a warmer climate for those creatures to live in.
