Marine waters cover 70.8% of the earth’s surface. And, if we substract the 5.5% area of the continental shelf, 65.3% of the earth’s surface is occupied by continental slope and rise, and deep-sea parts (data after Dietrich and Kalle 1957). The deep sea can be subdivided into several topographical units. There are deep-sea grabens<span> (15 in number), which cut deeper than 6,000 m. Deep-sea grabens are restricted to tectonic active regions near the foot of continental slopes.</span>
Answer:
B. Marine organisms.
Explanation:
The four factors that influence ocean currents are winds, water density (the amount of salt in water and its temperature), the ocean bottom topography and the rotation of the Earth (it creates two currents, one clockwise in the Northern Hemisphere and one counter-clockwise in the Southern Hemisphere). Marine organisms, plants or animals, are not counted as a factor that affects currents.
