4.  

What does "stratification" mean?

The unstable layering of higher density water on top of lower density water

The stable layering of lower density water on top of higher density water

The unstable layering of high salinity water on top of fresh density water

The unstable layering of cold water on top of warm water

5.  

Ekman transport creates regions of ______ in the ocean, which are associated with ______. Select all answers that complete the above sentence correctly. (select all that correct)

divergence, downwelling

convergence, downwelling

divergence, upwelling

convergence, upwelling

Antarctic Intermediate Water

North Atlantic Deep Water

Antarctic Bottom Water

Mediterranean Water

Explanation / Answer

1. the answer is Antarctic bottom water. This is because the out of the options given, we know that the temperature is inversely proportional to that of the salinity. That makes the mediterranean and atlantic water out of the list. Out of the remaining antarctic waters, he intermediate formations are characterised by low salinities. Therefore that makes the answer to be Antarctic bottom water which freeze at a very low temperature.

2. the answer to this question would be Antarctic bottom water. This is because salinity and density share a directly proportional signature towards each other.

3. the answer to this question would be East and downwelling. This is a basic information.

4. the answer to this question is the stable layering of low density water over the top of high density water. The general term of stratigraphy actually means a layered sequence which is graded according to the density of the particles used (can be rocks or water in this case).

5. the answer to this question is both b and c. This is because the behaviour of the ekman spiral is different with respect to their position to equator. In the northern hemisphere the ekman spirals are towards the right and divergent and hence upwelling. And then the vice versa.
