Help News from Science publish trustworthy, high-impact stories about research and the people who shape it. Which of the following would NOT increase biological oxygen demand (BOD)? c. Matter quality decreases when energy changes from one form to another Less saline water is found where there is more precipitation or river input. 64. Absorption of infrared radiation by atmospheric gases Which of the choices below are NOT true? This conveyer belt type circulation moves heat around the Earth through all of the ocean basis; the interconnected process of overturning circulation helps to regulate Earths climate. Seafloor spreading happens when two oceanic plates diverge, forming a crack where magma oozes up, which creates a mid ocean ridge. This mechanism is important, says Hu Shijian, an oceanographer at the Chinese Academy of Sciencess Institute of Oceanology, who was the lead author on the 2020 paper. a. deoxyribonucleic acid c.

Northern coniferous forest receives most of its precipitation in the form of snow in winter But if ocean currents are indeed becoming faster and shallower, there are many implications for the planet. d. Subduction Ocean waters are constantly on the move. e. A, The temperature of the lower troposphere can be influenced by atmospheric gases that include: Ocean currents are similar to winds in the atmosphere in that they transfer significant amounts of heat from Earth's equatorial areas to the poles and thus play important roles in . When the earth orbits the sun, the center of the Earth gets more direct sunlight than the poles. surface oceanic circulation results most directly in the. Heat makes water lighter, so it rises. c. scavenger This is triggered when winds blow water across the oceans surface, allowing deeper water to rise up to replace this displaced surface water. Currents can be broken down into two forms of circulation. This heat is then transported by currents and re-radiated, influencing regional air temperatures and climates all over the globe. For the time-decomposition analysis, it was found that over the eastern subcontinent of Africa, south of the equator . a. renewable resource Overdraft b. rainforest -> coniferous forest -> desert C Also known as thermohaline circulation, the .

Brazil and Indonesia d. composed of organic compounds and increases the water-holding capacity of soils c. acid precipitation falling throughout the northeastern United States 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. 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. a. Sulfur and nitrogen cycles It underlies the African Sergengeti and supplies millions of people with freshwater. The Great Pacific Garbage Patch is a collection of marine debris in the North Pacific Ocean. That is why it is easier to float in the ocean than in a fresh-water swimming pool or lake, and fresh water floats on top of salty ocean water. Ocean circulation is an essential part of How the Earth System Works. If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. a. magma e. suppressed thermocline in the Pacific Ocean, All of the following are examples of non-point source water pollution EXCEPT Ocean water moves in predictable ways along the ocean surface. Predation is similar to ________ in that both types of relationship benefit one of the interacting species while harming the other. When Shang-Ping Xie, a climate scientist at the Scripps Institution of Oceanography, saw Hus study, he immediately suspected that the structure of the oceannot windsplayed a leading role in the speedup. 3 & 7 a. The circulation of the ocean is a key factor in air temperature distribution. Adding heat decreases the density of water, while adding salt increases the density of water. c.

This type of ocean circulation is called thermohaline circulation (therme=heat, halos=salt) because the vertical movement is caused by differences in temperature and salinity (the amount of salt in water). e. The average temperature for tropical rainforest is constant throughout the year, The sinking of land due to the overpumping of ground water supplies These are more massive but move more slowly than surface currents. b. e. decreased precipitation in Australia, Which of the following are factors involved in soil formation? ocean circulation. Ocean currents flow like vast rivers, sweeping along predictable paths. More saline water masses are found in areas where there is a lot of evaporation because salt is left in the water, or in polar areas because as ice forms, salt is left in the water. Learn more in these real-world examples, and challenge yourself toconstruct a modelthat explains the Earth system relationships. The wavenumber spectrum of the oceanic circulation allows us to understand the energy distribution across spatial scales throughout the globe, reveals key bands of scales within the.
