• Kuroshio current

The highest salinity is found in

• Lake Van

• Lake Chad

• Lake Chad

• Red Sea

Sea water is saltier than rain water because

• sea animals are salt producing

• the air around the sea is saltish

• river wash away salts from earth and pour them into the sea

• sea beds have salt producing mines.

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.

• Both (A) and (R) are individually true and (R) is the correct explanation of (A)

• Both (A) and (R) are individually true, but (R) is not the correct explanation of (A)

• (A) is true, but (R) is false

• (A) is false, but (R) is true

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.

• Both (A) and (R) are individually true and (R) is the correct explanation of (A)

• Both (A) and (R) are individually true, but (R) is not the correct explanation of (A)

• (A) is true, but (R) is false

• (A) is false, but (R) is true

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.

• Both (A) and (R) are individually true and (R) is the correct explanation of (A)

• Both (A) and (R) are individually true, but (R) is not the correct explanation of (A)

• (A) is true, but (R) is false

• (A) is false, but (R) is true

Assertion (A) : Average ocean salinity generally decreases from equator the pole but tropical zone (20-30º) is characterised by maximum salinity. Reason (R) : The tropical zone owes its high salinity to high temperature, high evaporation and significantly low rainfall.

• Both (A) and (R) are true and (R) is the correct explanation of (A)

• Both (A) and (R) are true, but (R) is not the correct explanation of (A)

• (A) is true, but (R) is false

• (A) is false, but (R) is true

Consider the following conditions: 1. Anticyclone conditions with static air and high temperature 2. Cyclonic conditions with unstable air3. High precipitatioin with low evaporation 4. Low precipitation with high evaporation High salinity of ocean waters is associated with

• 1 and 4

• 2 and 3

• 1 and 3

• 2 and 4
