The Pacific and Atlantic Oceans are separated into north and south halves by:

a. North and South America.

c. the Prime Meridian.

b. the Equator.

d. currents.

The correct answer is B. the equator. The equator is the imaginary line found on the middle of the planet and it it splits not only those two oceans, but rather the entire planet into the north and the south hemisphere, and when you count parallels, the 0 is the equator, and then you got up or down from it.
