How is the enhanced greenhouse effect different from the greenhouse effect

The ‘greenhouse effect’ is how carbon dioxide, methane, water vapour and other molecules absorb the energy of specific wavelengths of electromagnetic radiation (i.e. light), and transfer parts of that energy to the atmosphere as heat. The effect stabilizes the earth’s temperature at levels that permit liquid water to exist. In other words, permit life forms as we know them.

The ‘enhanced greenhouse effect’ is the additions to the above effects caused by human activities that increase the concentrations of greenhouse gases in the atmosphere.

Explanation:

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
