6 Things You Didn’t Know About Currents
Currents in Science & Nature
-
On the world’s oceans, prevailing winds are the main factor shaping surface currents. Below 300 feet deep, current is the result of differences in water temperature and salinity. Cold water moves towards the equator where it warms, rises and flows back to the poles.
- Ocean currents pull nitrogen and phosphates from deep water to fuel the growth of plankton, the basis of the aquatic food chain. Cold ocean currents encourage the growth of plankton and warm currents restrict it. That’s why fishing is so good closer to the north and south poles.

The abbreviation AC/DC refers to alternating current and direct current. Thomas Edison developed direct current used in batteries. Nikola Tesla worked on alternating current, which is how power flows from a wall socket into a lamp. The 2019 Martin Scorsese film, The Current War, stars Benedict Cumberbatch as Edison and Nicholas Hoult as Tesla.
