Country A Atmospheric circulation transports heat over the surface of the Earth that affects the water cycle, including the formation of clouds and precipitation events. b. Ocean circulation is an essential part of How the Earth System Works. These waters are the upper 400 meters of the ocean. Being both cold AND salty makes it really dense, so it can sink very far. One is wind-driven circulation and the other is thermohaline circulation. Since the center of the Earth gets more sunlight, it is. d. subsidence a. a. a stretched rubber band This heat is then transported by currents and re-radiated, influencing regional air temperatures and climates all over the globe. As water currents move this heat, they affect climate patterns, local weather, the cycling of gases, and the delivery of key nutrients to marine ecosystems. c. carry diseases that infect native species $______________$, Soils contain a large amount of stored carbon. Because of the presence of continental barriers, those currents form loops called the subtropical gyres. Other observable results of short-term plate movement include the gradual widening of the Great Rift lakes in eastern Africa and the rising of the Himalayan Mountain range. b.

Scientists have found new evidence that the Atlantic Ocean's circulation has slowed by about 15 percent since the middle of the last century. Ocean circulation is such an important process in the Earth system because currents transport heat, oxygen, nutrients, and living organisms. d. Seasonal changes in temperature and precipitation Deep below the surface, there are currents that are controlled by water density, which depends on the temperature and salinity of the water. One notable exception was the Gulf Stream, which is likely slowing for an unrelated reason: As Arctic ice melts, it dilutes the sinking, salty water in the North Atlantic that pulls the current northward. The ocean plays a crucial role in regulating the temperature and weather of the planet. e. it means that people will suffer, The Law of Conversation of Matter says The environmental impact of a population on a given area depends on, Surface oceanic circulation results most directly in the.
