About how long does it take deep ocean currents to travel all the way around Earth? A. many days B. many years C. many hundreds of years D. many thousands of years

It takes many years for a deep ocean current to travel around the Earth.

Explanation:

The movement of ocean water in a specific pattern is referred to as ocean current or thermohaline circulation. When these currents flow below a certain depth, they are called deep ocean currents. These currents tend to move very slowly owing to the pressure exerted by the water slabs above and underneath them. They are also confronted by numerous hurdles on their way around the earth forcing them to change their course every now and then. This is generally why it takes many years for a deep ocean current to travel around the Earth.
