At which boundary will you find the deepest earthquakes?
Divergent Boundary
Transform Boundary
Convergent Boundary
Oceanic Boundary
When two oceanic plates collide at a convergent boundary, one will subduct under the other one. What determines this?
The left plate will always subduct because it was there first
The colder plate will subduct because it is more dense
The hotter plate will subduct because it is attracted to the heat radiating up from the mantle
The older plate will subduct because it is used to other plates roaming over it
