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

Explanation:

Moves cold water: The deep ocean currents forms a global conveyor belt to transport cold water from the poles to the equator where they get warmed up and back.

Moves in a circular pattern: the deep ocean currents forms a cyclic current pattern round the globe.

Caused by difference in density: density difference between cold and warm water vastly accounts for this.

the correct option is option a
