It involves all the processes through which salt moves from the ocean into the lithosphere, to a certain extent into the atmosphere, and back into the oceans. Salinity changes with depth, but the way it changes depends upon the location of the sea. Now let's see how to learn fast the concepts associated with hydrosphere. The energy created by the motion of molecules in the ocean is measured through Ocean Temperature. Salinity at depth is very much fixed because there is no way that water is ‘lost’, or the salt is ‘added.’ There is a marked difference in the salinity between the surface zones and the deep zones of the oceans. The north and south Atlantic have high salinity – these are areas where there are strong winds and not much rain. This stage is officially known as the Civil Services (Preliminary) exam, but in common parlance, aspirants refer to it as UPSC Prelims or IAS Prelims. These deep-ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline). Ocean Floor Configuration Spanish essays for beginners how to use a bibliography in an essay, academic explanation essay example? But this doesn’t mean that tropical oceans will have higher salinity because of the points mentioned in the next point. The National Centre for Polar and Ocean Research (NCPOR) has predicted an increase in the expansion of Amery Ice Shelf (AIS) boundaries from its 2016 positions.. Stratification and Mobility: (a) Concepts- equality, inequality, hier-archy, exclusion, poverty and depri-vation. It also influences the composition and movement of the sea: water and the distribution of fish and other marine resources.
