Answer 2

Answer:

Salinity is unequally distributed in the topics and fluctuates with variation in temperatures and weather patterns.

Explanation:

• As the seawater contains 35 parts per thousand of dissolved salt content in each liter. The salinity can range from 33 to 37 ppt. Wind and rainfall are considered as the dominant salinity controlling factors in the distribution of salinity around tropics of cancer and Capricorn.

• Its due to the presence of more land areas in the northern hemisphere that the content of salts in the water is higher as compared to the lower southern hemisphere which is known as the water hemisphere.

• As it has been found the red sea consists of the saltiest sea like the dead sea having a salinity of 41% situated in tropics of cancer. Atlantic ocean record a salinity of more than 36 ppt.

• While places near the equator record low or normal salinity and places near the amazon river of south America record heavy salinity of 37 ppt, as river also raise the salinity of oceans.
