Which best describes how the atmosphere's CO2 content was regulated before the Industrial Revolution? Which best describes how the atmosphere's CO2 content was regulated before the Industrial Revolution? Inputs of CO2 to the atmosphere resulted from cellular respiration and widespread use of fossil fuels. These inputs were much greater than the uptake of CO2 by producers. CO2 was taken up by organisms for use in cellular respiration; a similar amount of CO2 was released by plants and other producers. CO2 was released by organisms as a by-product of cellular respiration; photosynthesis contributed additional CO2 to the atmosphere. CO2 was released by organisms as a by-product of cellular respiration; a similar amount of CO2 was absorbed by plants and other producers.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
