Where does subduction occur?

a. at hot spots
b. at mid-ocean ridges
c. at continental shelves
d. at deep ocean trenches

Well, the answer I always learned was "where two places collide"

So I think your best bet is answer C.

This is cause they often collide and grind against each other, which btw is what causes earthquakes if you didn't know.

if, i suppose that a bee stings me swinging my hand away from a bee. then that if, i persist patient when a bee or wasp areas on your surface to investigate a scent or to take h2o and i secreting heavily, the bug ultimately will move of its personal agreement. if i don't need to set for it to disappear, lightly and gently wipe it off with a part of the paper.

the answer is true ; ) have a good day
