Which characteristics describe deep ocean currents? check all that apply.
move slowly
caused by wind
move cold water
move in a circular pattern
caused by differences in density

Options (1), (3), (4) and (5)

Explanation:

The deep ocean water refers to the water that is present at the bottom of the ocean. This deep water is highly dense, and are rich in essential nutrients including oxygen. Sunlight cannot penetrate into the deeper layer, as a result of which these water remains much colder and moves at a much slower rate in comparison to the surface waves. These deep ocean currents are generated by the density differences due to two factors namely, temperature and salinity.

These currents are moved from the equatorial region to the poles and again comes back from the poles to the equator, forming a circular pattern. This circulation of water is responsible for the various climatic conditions that occur at different places.

Thus, the correct answers are mentioned above.
