Concept explainers
Interpretation:
The change in salinity as the ocean water cools should be determined.
Concept introduction:
The ocean water is a mixture of salt, water, sea debris and other chemicals released from the ocean life and materials present in the ocean. The temperature of the ocean is higher in the upper region, as this region is penetrated by the sunlight, but in depth, the temperature of the ocean decreases,
Answer to Problem 130A
As the ocean water starts cooling, the salinity of the sea increases.
Explanation of Solution
According to the graph, below 1000 meters depth, the temperature of the ocean starts to fall and it is around 4oC. with decrease in the temperature, the salinity of the water increases. At 1000 m, the % salinity is around 34.5. which increases to approximately 35.
