In some parts of the world, forests are being cut down and burned to clear land for new homes

and new farmland. A negative effect of these

activities might be

(1) an increase in global warming

(2) destruction of the ozone shield

(3) a decrease in the average temperature of the

atmosphere

(4) an increase in biodiversity of the deforested

areas

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
