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.
Earthquakes generate compressional waves (p-waves) and shear waves (s-waves). Compared to the speed of shear waves in a given earth material, the speed of compressional waves is the fastest.
Because of this the compressional waves are the first waves to arrive on a complete record of ground shaking. They are also called P waves, which derives from this fact - P is an abbreviation for primary, first wave to arrive.<span>They typically travel at speeds between ~1 and ~14 km/sec.</span>
