What is the most abundant component of salts in sea ?
Average salinity of water of Arabian Sea is
Salinity in ocean water decrease when
Assertion (A) : Oceanic salinity is higher along Tropics of Cancer and Capricorn.Reason (R) : Increased evaporation coupled with relatively more insolation along these latitudes causes higher oceanic salinity.Code
Assertion (A) : The amount of salinity in the tropical coasts of continents.Reason (R) : The trade wind causes upwelling of water in the western coasts and the water is piled up in the eastern coasts of continents.Code
Assertion (A) : Despite low evaporation and stable stratification of the atmosphere, salinity is high in polar regions.Reason (R) : Sea water freezes leaving the remaining water saline than before.Code
Consider the following statementsSalinity of water in the equatorial oceans decrease because1. large rivers like Amazon and Congo enter into the sea2. evaporation is less3. waters from Arctic and Antarctic mix with the waters of Equator4. of heavy rainfallWhich of these statements are correct ?
Assertion (A) : Average ocean salinity generally decreases from equator the pole but tropical zone (20 - 30 ) is charcterized by maximum salinity.Reason (R) : The tropical zone owes its high salinity to high temperature, high evaporation and significantly low rainfall.Codes :
Consider the following conditions1. anticyclone conditions with static air and high temperature2. Cyclonic conditions with unstable air3. High precipitation with low evaporation4. Low precipitation with high evaporation High salinity of ocean waters is associated with
