Which qualities describe the entire open-ocean zone? check all that apply. few nutrients high pressure ample sunlight varying salinity low temperatures

- few nutrients

- high pressure

- low temperatures

Explanation:

1. Few nutrients:  open-ocean zone is located way far from the land, which is the main source of the essential nutrients.

2. High pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.

3. Ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface.

4. Varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.

5. Low temperatures:  the temperature of open-ocean zone ranges from a low of -2°C to an average of 17°C.
