Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. Air is a relatively poor thermal conductor (which means it is a good insulator), so conduction represents only a small part of the energy transfer between the Earth and the atmosphere; equal to about 7% of the incoming solar energy. 6 & 9 a. renewable resource a.

The new findings also suggests that in much of the ocean, lower waters, some 400 meters or so down, would slow as warm upper waters take up more and more of the movement, Xie says. c. scavenger which best describe chlorofluorocarbons (cfcs), volcanic eruptions release them into the atmosphere , they were targeted for banning in 1987 as a part of the Montreal Protocol, which of the following best describes the mechanism of the greenhouse effect in the earth's atmosphere, infrared radiation from the earth's surface is absorbed by gases in the atmosphere, which of the following greenhouse gases does not exist naturally, increasing the amount of greenhouse gases in the troposphere will reduce heat radiated back to space in the form of, which of the following energy sources is a chief contributor to greenhouse gas emissions as well as increasing environmental mobility of mercury, which of the following molecules is not considered a greenhouse gas, which best describe the impact of atmospheric carbon dioxide and stratospheric aerosols, both carbon dioxide and aerosols contribute to global warming, Anthropogenic water vapor does not contribute significantly to global warming because, water vapor has a short residence time in the atmosphere, Terrestial biomes vary in net primary productivity due to, the suns radiation provides the energy for, plant growth, ocean currents, hurricanes, and plate tectonics, phytoplankton are most abundant in the upper few hundred feet of most bodies of water because, sunlight does not penetrate to great depths in water. Properties of air, water, and land Others are confined to particular regions and form slow-moving, circular pools. Adding heat decreases the density of water, while adding salt increases the density of water. Image Credit: NASA Aquarius/SAC-D mission.
