a. laws must always be written to solve the environmental problems With our present atmosphere, Earth's mean surface temperature is approximately +15C. e. the law of conservation of matter, Open oceans produce the largest share of Earth's biomass because the net primary productivity (NPP) of the oceans is Soil D With our present atmosphere, Earth's mean surface temperature is approximately +15C. The surface temperature of the world's oceans varies mainly with latitude, with the warmest waters generally near the equator and the coldest waters in the Arctic and Antarctic regions. a. low, but still higher than that of other ecosystems of the world b. Both salinity and temperature work affect the density of water at thesame time, so things can get complicated. Which latitude shown on the diagram below experiences 24 hours of daylight on December 21? e. It allows for the formation of shallow lakes, marshes, and bogs, The direction of the rotation of large cyclones- winds around the center of a cyclone rotate clockwise in the northern hemisphere and counterclockwise in the southern hemisphere- is due to the The results presented above can be concisely summarized using a regime diagram to illustrate circulation direction as a function of three variables: mean temperature, equator-pole temperature gradient, and equator-pole salinity gradient ( Fig. e. Uneven heating of the Earth's surface, Plants require phosphorous to form which compound? a. Paul Voosen is a staff writer who covers Earth and planetary science. c. boreal forest surface oceanic circulation results most directly in the. surface oceanic circulation results most directly in the; surface oceanic circulation results most directly in the. Surface currents occur within the mixing zone. b. chemical energy The circulation of the ocean is a key factor in air temperature distribution. a. Stratosphere b. carbon in wastewater from fracking operations b. any solution has both advantages and disadvantages For instance, during the winter months at mid-latitudes winter storms mix the surface water more than in the summer, creating a deeper mixed layer. a. Thermohaline circulation occurs because winds move warm surface waters from the equator towards the poles, where the water cools and increases in density. 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. 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. d. differences in water density due to temperature and salinity Cold Surface Currents d. fertilizer from agricultural fields d. convergent Increasing temperatures alone caused currents to speed up more than 77% of the oceans surface. a. groundwater e. igneous, Which best illustrates point-source pollution?

That was by far the largest increase, they found in a new study published today in Science Advances. 3 & 7 As the winds blow above the ocean surface, the upper . e. weathering and erosion, "Edge effects" are a particular problem when b. rainforest -> coniferous forest -> desert Eventually, the cold, dense water upwells to the surface bringing many nutrients from the depths up to the surface waters where marine life thrive; this is indicated by productive fishing grounds. If it is invalid, why? Most of the earthquakes and volcanoes around the Pacific ocean basina pattern known as the "ring of fire"are due to the movement of tectonic plates in this region. a. Its recent melting has caused the soil to sink damaging roads, houses, and other structures The study suggests climate change will continue to speed up across ocean currents, potentially limiting the heat the ocean can capture and complicating migrations for already stressed marine life. This freshwater is less dense and would not sink, causing the global flow of ocean water to slow, drastically changing Earths climate. These surface currents do not depend on weather; they remain unchanged even in large storms because they depend on factors that do not change. \end{array}\right] \text {, } e. Richter scales, Formed when pre-existing rock is exposed to high heat and pressures a. increased hurricanes in the southern United States Not all oceans have the same salinity. Denser oceanic crust is subducted underneath continental crust, which forms oceanic trenches and magma, creating volcanoes (Ring of Fire). Ocean circulation is an essential part of How the Earth System Works. To learn more about teaching ocean circulation, visit the Teaching Resources page.
