Vertical movement of deep ocean water is caused by forces of wind phytoplanktons dissolved nutrients variations in density plz answer and you

variations in density

The vertical movement of deep water is influenced by the the variation of density of water on the vertical layers of the ocean. The variations that occur in the oceanic water occurs due to variation in the salinity and temperature of water. The saltier water is more denser and tends to sink, the cold water exhibit more density and tends to sink, the warm water floats over the superficial layers due to low density.

4.) metal

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
