To see more answers head over to College Study Guides. In certain areas near the polar oceans, the colder surface water also gets saltier due to evaporation or sea ice formation. Three experiments are analyzed, a present day control run, and two freshwater hosing runs. Thermohaline circulation is mainly due to the sinking of high density surface water. Thermohaline circulation is mainly due to. When ocean water in these areas gets very cold, sea ice forms. Nevertheless, it is interesting to compare with the observationally based analysis of water-mass transformations in the Atlantic by Speer (1993). Question: Thermohaline circulation is mainly due to. These deep ocean currents supply heat to polar regions and thereby regulate sea ice formation. 1) is that part of the ocean circulation which is driven by density differences. The adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of sea water. D) warm water being added to the ocean due to industial waste. 2x^2 + 3x + 1 = 0; Winds drive ocean currents in the upper 100 meters of the ocean’s surface. Fresh water is lost due to a combination of evaporation and ice formation.

Sea ice is mainly formed from non- to slightly saline water. The term “thermohaline circulation” refers to a serpentine pattern of deep ocean currents that are driven by density differences – mainly caused by variations in salinity and temperature – as opposed to near-surface currents that are driven mainly by wind. Thermohaline circulation is mainly due to. As ocean water freezes at the poles it concentrates salt, and the colder, denser water sinks. (Points : 2) ! thermohaline circulation Movement of ocean water caused by density difference brought about by variations in temperature and salinity. Since seawater density depends mainly on temperature and salinity (section 6.3), this circulation is referred to as thermohaline circulation. Upload Date: 10/06/2017. The ocean currents, the movement of the ocean in the surface layer, are driven mostly by the wind. Hence, this cell is mainly due to circulation the Indo-Pacific, in agreement with the description above. Weegy: 2x^2 + 3x = -1; = 9 - 8 Virtual Teaching Assistant: John B. variations of the thermohaline circulation. What is the thermohaline circulation (THC)? The Thermohaline Circulation:Sinking of cold water at high latitudes gives a poleward flow in the surface layers and equatorward flow in the deep oceans with slow rising motion outside the polar regions. The surrounding seawater gets saltier, increases in density and sinks. As opposed to wind-driven currents and tides (which are due to the gravity of moon and sun), the thermohaline circulation (Fig. This 7 words question was answered by John B. on StudySoup on 10/06/2017. As the warm water is driven north, mainly by the Gulf Stream, it cools down. What is the amount of work done when a body moves under a force of 1 N at a distance of 1 meter in the direction of the force? 1 The density-related thermohaline circulation drives a series of ocean currents, often referred to as the “global conveyor belt”, or the “meridional overturning … creating equal ... What is the value of b 2 - 4ac for the following equation? Deep ocean currents, on the other hand, are mainly a result of density differences. It influences the rate of sea ice formation near the poles, which impacts other aspects of the climate system (such as the albedo). The adjective thermohalinederives from thermo-referring to temperature and -halinereferring to salt content, factors which together determine the density of sea water. Which became a new focus for the NAACP after 1950? The resulting circulation maintains the contrasts between the upper and lower regions of the ocean. B) winds causing circulation of ocean water. Such currents are driven by water density and temperature gradients. Report Error Since the process that forms dense water is mainly linked to the reduction or rise of salinity, due to the formation of ice, the thermohaline currents form mainly on the poles. thermohaline circulation. The repeated reflection that results in persistence of sound is called, A force of 20 N displaces an object through 2 m and does a work of 20 J. The main processes that increase seawater density are … The thermohaline circulation is mainly driven by the formation of deep water masses in the North Atlantic and the Southern Ocean caused by differences in temperature and salinity of the water. The angle between the force and displacement is. Answer to: Thermohaline circulation is mainly due to By signing up, you'll get thousands of step-by-step solutions to your homework questions. Thermohaline circulation The water of the great world ocean is, like its crust and interior, constantly in motion. Thermohaline circulation, the component of general oceanic circulation controlled by horizontal differences in temperature and salinity. ; ? It continually replaces seawater at depth with water from the surface and slowly replaces surface water elsewhere with … It was discovered that all of these currents can be considered together as a global circulation known as the THERMOHALINE CIRCULATION. Question Level: Basic Karma: Free . This means that the salt in ocean w… The driving 'pump' for this occurs in the far north. A) cold, dense ocean water sinking and warmer water replacing it. The thermohaline circulation is mainly triggered by the formation of deep water masses in the North Atlantic and the Southern Ocean caused by differences in temperature and salinity of the water. Share what’s outside your window and all around you. Results show that as the thermohaline circulation weakens due to freshwater forcing in the northern North Atlantic, the Bering Strait throughflow weakens, and even reverses its direction, and the export of 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. The great quantities of dense water sinking at polar ocean basin edges must be offset by equal quantities of water rising elsewhere. 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. In which of the following examples will an athlete have maximum accelerated motion? A regime shift could occur due to the release of large amounts of freshwater into the North Atlantic Ocean. Both excess supply and excess demand are a result of, Market economics produce goods that blank. Deep ocean currents are generally called “Thermohaline Circulation” . Thermohaline circulation is mainly due to cold, dense ocean water sinking and warmer water replacing it. (3)^2 - 4(2)(1) The consequences of a warming Earth on its oceans are not, of course, confined to their peripheries but chemistry, circulation, and biology of the wide-open ocean will change in numerous small and large ways and over short and long periods of time. Insights about what likely will happen to the open seas are derived largely from computer simulation models, … Distinguish For a science fair project, Ina wanted to investigate if flower color influenced the attraction of butterflies and moths. b^2 - 4ac; a = 2, b = 3, c = 1; The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. Thermohaline circulation is mainly due to. The term thermohaline circulation is used increasingly to apply not only to the direct response to surface buoyancy fluxes but also to flows whose characteristics are altered significantly by upwelling or mixing. The thermohaline circulation is that part of the large-scale ocean flow driven by diapycnal fluxes, rather than directly by the wind. Thermohaline circulation plays an important role in supplying heat to the polar regions. Thermohaline is derived from the Greek: thermo- for heat and … Currents carrying colossal amounts of water transport it around the globe, by what has been named "The Great Ocean Conveyor" (Broecker, 1991). The Thermohaline Circulation (THC) also referred to as the “Great Ocean Conveyor” or the Meridional Overturning Circulation (MOC), can be defined as the density-impelled circulation of the oceans. These, however, are superimposed on the much more sluggish circulation driven by horizontal differences in temperature and salinity—namely, the thermohaline circulation. View Answer These two regions don't mix except in certain special areas. As opposed to wind-driven currents and tides (the latter are due to the gravity of moon and sun), the thermohaline circulation (often abbreviated as THC) is that part of the ocean circulation which is driven by fluxes of heat and freshwater across the sea surface and subsequent interior mixing of heat The great quantities of dense water sinking at high latitudes must be … Thermohaline circulation The general circulation of the oceans consists primarily of the wind-driven currents. Transfers heat from the equator to Europe/North America, causing temperate climate. This movement has been halted in the past due to large inflows of freshwater. Thermohaline circulation is the global movement of ocean water from the surface to the deep ocean, which has a major role in regulating global climate. What is the heat generated (in J) in a heating element of resistance 800 Ω when a current of 0.2 A passes through it for 40 seconds? THERMOHALINE CIRCULATION 1. The thermohaline circulation, often referred to as the ocean's "conveyor belt", links major surface and deep water currents in the Atlantic, Indian, Pacific, and Southern Oceans. Discuss.
