Explain this interaction and be sure to mention the mechanical impacts (streams, deposition, erosion, frost wedging) as well as chemical impacts (oxidation, hydrolysis, carbonation). Choose at least one of each (1 mechanical and 1 chemical) to explain in your answer.

answer: - 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

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!
