Question

2) At which latitudes are the highest surface salinities found? Suggest a reason why.

3)Of the 2 oceans, which has the higher average surface salinity?

Ocean Composition Temperature and salinity (the amount of dissolved salts in the water) affect the density of the water. Ocean salinity differs by small numbers, so oceanographers need to be accurate when measuring salinity. Changes in density caused by wind and currents at the surface affects the deep-ocean currents. Density ultimately affects the objects that exist in the water, such as whales seaweed, and submarines. The saltier the water, the more buoyant an object becomes Therefore, salt waters are constantly trying to find their "place" in the ocean according to their salinity. Very salty water is more dense, and will sink more, thus very salty water is found at the bottom. Less salty water is less dense and will float on top of the more dense salty water. Deeper water depths tend to be more homogenous. The gradational boundary bet ween the surface-water salinities and the deep water salinities is known as the halocline travel as they move through the different waters of the world. Question 1) Table 1 below lists the approximate water salinities at various latitudes in the Atlantic and Pacific Oceans. Using the data provided construct a salinity cure for each ocean. Your X-axis value will be the latitudes and the Y-axis values are the salinity values. Use different colored pens or pencils for each ocean. Table i Water Salinities of the Atlantic and Pacific Oceans Latitude tlant Ocean Ocean 60 N 33.0 31.0 50 N 33.7 32.5 34.8 40 N 33.2 30 36.7 34.2 20 N 36.8 34.2 10 N 36.0 34.4 35.0 uator 10 o 35.9 35.2 20 S 36.7 35.6 30 S 36.2 35.7 40 S 35.3 35.0 50 34.3 34.4 60 S 33.9 34.0

Explanation / Answer

part 1 of the answer:

The salinity is the highest at around 20° and 30°. The reason for the higher rates of salinity is due to the fact that at these latitudes is where many of the earth's deserts are located and the evaporation rate of water is high.

part 2 of the answer: from the given data, we can see and calculate clearly that Atlantic ocean has a greater average surface salinity than pacific ocean.
