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.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
