1. When the partition was removed, there was a mixing of the fresh water and salt water.

2. The motion described above was produced by the flow of water caused by the removal of the partition.

3. Mixing of fresh water and salt water could occur in estuaries, where rivers flow into the ocean, or in coastal areas where groundwater mixes with sea water.

4. The zone of mixing is identified in the experiment by the gradual blending of the fresh and salt water layers.

5. The zone of mixing would become thicker after blowing across the surface because the increased turbulence would help mix the two layers more effectively.

6. The slow mixing from 2.5 to 9 minutes is likely caused by diffusion, in which molecules of fresh and salt water mix together over time.

7. The zone of mixing may appear thinner after blowing across the surface the second time after 9 minutes, as the initial mixing caused by the turbulence could have already taken place.

8. The stratification caused by differences in salinity does not appear to be permanent, as it can be easily mixed together with external forces like blowing across the surface.

9. The halocline is a zone of rapid increase or decrease in salinity, as it is where two distinct layers of water with different salinities meet and mix.
