So to answer the first part of your question, technically yes, but the surface is less dense by such a small amount that it can be considered a negligible difference. Similar to a person trying to walk in a straight line across a spinning merry-go-round, winds and ocean waters get deflected from a straight line path as they travel . b. all of the above 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. When the earth orbits the sun, the center of the Earth gets more direct sunlight than the poles. b. sedimentary b. Exosphere Temperature is another factor that affects density.

Is the following assignment statement valid or invalid? surface oceanic circulation results most directly in the Warmer water masses are found near equatorial regions and colder water masses are found near polar regions. APES Unit 1 Flashcards | Quizlet In other words, salty water has more materials in the water than freshwater which makes it more dense than freshwater. d. Nitrous oxide a. Troposphere This freshwater is less dense and would not sink, causing the global flow of ocean water to slow, drastically changing Earths climate. B Low High Environmental Protection Agency. Density differences are the key to why ocean waters move. a. a. Stratosphere The ocean also has deep underwater currents. c. Bacterial contaminants of surface water d. The building of dams The activity below the ocean surface shows a strong subsurface wave of warm anomalies, also known as a Kelvin Wave, expanding from the west. All this heating and cooling and melting and thawing creates a layered ocean: warmer fresher water on top, cold salty water at the bottom. Which of the following is the best explanation for this difference? b. Exosphere b. b. runoff from farm land Surface Currents -- Surface Circulation. Surface currents, also called horizontal currents, are primarily the result of wind pushing on the surface of the water, and the direction and extent of their movement is determined by the distribution of continents.

Marine microbes and wildlife could be subjected to shallower, hotter, and faster surface waters. Oceans cover 71% of the globe, storing and transferring heat energy around the world. c. decomposer Both temperature and salinity impact where the water goes as it circulates throughout the globe. Instead, they currents are deflected because of the Coriolis force, which is due to the Earth's rotation. d. carnivore At mid-latitudes, the atmospheric westerlies induce eastward currents in the ocean while the trade winds are responsible for westward currents in the tropics (Fig. This is an interesting study with a provocative finding, says Sarah Gille, a physical oceanographer at Scripps.

Currents that move up and down in the water column, also called vertical currents, are created by differences in the density of water masses, where heavier waters sink and lighter waters rise. If Earth had no atmosphere, the mean surface temperature would be approximately -15C. e. suppressed thermocline in the Pacific Ocean, All of the following are examples of non-point source water pollution EXCEPT Salinity changes can create ocean circulation changes that, in turn, may impact regional and global climates.
