Accounting for the top-down nature of ocean warming changes that picture, she adds. Image Credit:Major Ocean Currents (source: US Navy Oceanographic Office). This cold, salty water near the poles (primarily in the North Atlantic and near Antarctica) sinks and spreads along the bottom and eventually rises back towards the surface of the ocean. Why is drinking plenty of water a benefit to your excretory system? b. sedimentary All this heating and cooling and melting and thawing creates a layered ocean: warmer fresher water on top, cold salty water at the bottom. b. sand The thermohaline ocean currents have a strong effect on the Earth System. 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. d.
