water logging and salinity
Halocline
It is caused by the wind or the cold of the water surrounding it.It is also caused by salinity (saltiness).
ocean currents are caused by difference in temperatures and salinity lol :) :P hehe
salinity, pollution, bushfires and drought ect...
differences in temperature and salinity.
Caused by the number of freshwater rivers flowing into the sea, which is generally known as 'brackish'.
Salinity is at its worst in the far west of New South Wales, particularly along some reaches of the Darling River. There are also increasing problems with rising salinity levels around Dubbo and Wagga Wagga. See the related link for a map.
Both the Murray and the Darling Rivers of Australia suffer rising salinity problems.
The Chinese caused all sorts of problems on the goldfields. Why?
Some problems caused by war is loss of life and economic crash.
The ocean currents move because of different densities caused by ocean temperatures and salinity.
