List the 6 major elemental constituents of river water in order of decreasing abundance. Compare your lists from questions 1 and 2. In comparing the chemistry of the two waters, it is clear that the occurrence and abundance of elemental constituents is very different. List some possible causes for the chemical differences. Part B. Residence times.
Residence time is defined as the average time that a substance remains dissolved water.
It can be calculated by dividing the amount of a substance divided by its rate of addition or removal form the area. Ions have varying residence times in sea water, that is they remain dissolved in the ocean water for certain periods of time. Examine table 2 and then answer the associated questions. Part C. Global Distribution of Ocean Salinity. Examine the world maps and charts of ocean salinity and ocean temperature provided in your text and then answer the following questions.
