your environment?
b. Give an example of an observation that could be made with-
out using an instrument, but that would be improved by us-
ing one.
c. Give an example of an observation that could not be made

lets say all you have to do is look around when your outside and look at the dirt or something and think ' how did it get here' was a man-made or natural.

Explanation:

pls put me brainiest!!

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
