thermocline
the twilight zone
If at "normal" temperatures, it is called condensation. If at extremely cold temperatures, it is called liquefaction.
It is generally called solidifying, but if it solidifies because of lower temperatures it is called freezing.
Density variations of seawater with latitude are very similar to those for temperature variations with latitude. Because of the influence of temperature on seawater density, low latitudes exhibit lower densities at the surface that rapidly increase with depth. Higher latitudes exhibit little or no difference in density owing to the lack of a thermocline. Such a rapid change in density with depth is called a pycnocline, and like a thermocline is absent at higher latitudes.
A rapidly falling air pressure is often associated with the approach of a storm or low-pressure system, which can bring changes in weather such as strong winds, heavy rain or snow, and rapidly dropping temperatures.
That is called evaporation when it happens slowly; if it happens more rapidly it is called vaporization.
Salts are removed from seawater through a process called desalination. This can be done through various methods such as distillation, reverse osmosis, or electrodialysis. These methods help separate the salts from the water, resulting in fresh water that is suitable for consumption.
Technology, trends, and weather can all change rapidly.
It means to change rapidly.
Yes, this is a physical change.
pycnocline
Yes, but not much. A ship is more buoyant in seawater, and thus less of the hull is in the water (thus less resistance).
