Submarine canyons were most likely formed by: select one: a. scouring by glaciers during the last ice age. b. deposition of terrestrial sediment. c. earthquake activity. d. erosion by turbidity currents. e. erosion by major rivers in the past.

Submarine canyons were most likely formed by erosion by major rivers in the past (option e)

Explanation:

A submarine canyon is a deep, relatively narrow, V-shaped depression whose bottom generally has a continuous slope. It can extend from the continental shelf to the great ocean depths.

Submarine canyons are habitats that appear interrupting the apparent homogeneity of the continental shelf. They play an important role in channeling organic matter. They transport sediments from the continental shelf to the deep ocean. Submarine canyons are usually found at the mouths of the rivers and are formed by the gigantic erosive power of the water that is slowly sculpting it from the continent, to the abysmal depths.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
