the density does not change, only the pressure

Sea water is a homogenous mixture, according to the key to correction :>
yes they do a lagoon is exactly like the sea except not in size or deepness just in the way the water is. In other words the lagoon is like a mini sea just extremely tiny. So yes lagoons do have salt in them but not always it depends on how long the lagoon has been there and if the sea has been made access some how. Lauren bell
precipitation equals rain. As when sea water evaporates clouds form eventually leading to rain fall refilling the sea with the previously evaporated water. But not all rain water returns to the sea which is how the sea level changes due to precipitation.
The level of gulf water and sea water depends on the influence of the moon and sun, and contantly changes with the ebb and flood of the tides.
it effects the animals: it can kill them poison them water: the ocean's color changes
Most rivers are subject to tidal flows just as the sea is. Additionally, water flowing into the river from the surrounding land changes the level.
As there is a higher concentration of salt in the sea water, salt will diffuse into the cell and this will cause the cell to shrink.
as mid-ocean ridge forms it causes the land to pen and the lava flows our. the lava in the sea/ocean changes the temp. of sea water as it is hot.
Sea salts are those which are isolated from sea water as NaCl, MgCl2, CaCl2, but some salts are produce on earth by rain water or other geological changes as Nitrate, Carbonate and Silicate salts.
Water drains away (land contour changes, sea level changes) mud turns to dirt,' grass
it changes by how the weather is outside. Weather is what changes the climate in the sea
