= 1 point) How do submarine
canyons form?
a. | Via rivers, which erodes the continental shelf and then carves a
canyon into the continental slope. | b. | Via the longshore current,
which erods the continental shelf and then carves a canyon into the continental
slope. | c. | Via the waves, which erodes the continental shelf and then carves
a canyon into the continental slope. |
