How does saltwater intrusion happen?
Saltwater intrusion is the movement of ocean water into fresh groundwater that causes contamination of the freshwater by salt. This is a process of nature and usually occurs near the coastlines where the fresh groundwater level approaches the same level as the sea.
Why salt water and fresh don't mix?
Unfortunately salt water and fresh water do, in fact, mix. You can easily perform an experiment yourself: 1) Take two glasses and fill them with tap water, or filtered water, or holy water if you'd like. 2) Add salt to one. The salt can be table salt you buy at the store, with or without iodine, sea salt, rock salt or any other type of actual sodium chloride you can buy. 3) Taste the water in both glasses. One is salty, the other isn't. 4) Add equal parts of water from both glasses to the a third glass. 5) Taste the water. It's salty, but less salty than the glass of salt water you made. That's because the two waters mixed and made a glass of water has 'saltiness' somewhere in between the fresh water and the salt waters you made. Having said all that, well out at sea from the mouth of the Amazon, the surface water is still fresh, due to density stratification. The same effect is seen in the New Zealand Fiords, where wave action is slight.
What would happen to a salt water plant if you put in fresh water and why?
The plant is most likely to die because the salt water already killed the root cells. It also depends on the concentraition of the plant. some plants are very sensitive when fresh water is placed in ONLY salt water plants
Does rock salt dissolve in water?
Yes. Rock salt, which is largely the same as table salt, will dissolve in water.
How are fresh water and ocean water alike?
Salt water and Fresh water are chemically identical (H20) with the difference being that salt water has sodium chloride (NaCl or common household salt), an ionic compound made from 1 positively charged sodium ion and 1 negatively charged chlorine ion, in solution (disolved into it) The salt disolved by the relatively strong hydrogen bonds in water, attracting the charged ions and pulling them out of a solid state. These hydrogen bonds give water some of its "special properties" such as stickyness, wetness and being a liquid at room temperature, Big exciting things for chemists. It is this presence of Ions that allow salt water to conduct electricity as the ions can carry charge through water, which completely pure water cannot do. Pure water also has a lower freezing temperature than Salt water as the hydrogen bonds in "fresh water" are attracted to other H20 molecules rather than the ions in solution. Pure water has a water potential of 0, salt water is less than this. Salt water is also salty, Fresh water isn't.
Why does salt water lose heat faster then fresh water?
The specific heat of both are essentially the same. i.e. it doesn't.
Why is salt water and fresh water the same?
Salt water is salty because of chemicals that are dissolved in the water. The water is still H2O, the same as fresh water.
Which is lighter fresh or salt water?
Salt water is denser than fresh water, so fresh water is lighter than salt water. This is due to the dissolved salt and other minerals in salt water, which increase its density.
is the water salt water or fresh water?
this depends on where the water is, if its in a swamp in the everglades it is considered brackish which is both salt and fresh water, in the ocean the water is salt water, if your at a lake, pond, or stream then it is fresh water, and if you are talking about water in a salt water pool the water isnt really salt water it just has chemicals to have the same effect.
What is the differencein pressure between salt water and fresh water at different depths?
Currents and thermal gradients aside, salt water is slightly more dense than fresh water, so (at the same depth, for the same temperature) the pressure in salt water will be creater than for fresh water. The difference in pressure will be (pressure in fresh water) x (density of salt water/density of fresh).
Will fresh water or salt evaporate faster?
At the same temperature fresh water evaporates faster.
What is the rate of fresh water evaporation compared to salt water?
the same. the salt isn't evaporated, only the h2o, so fresh and salt water evaporate the same unless there is another liquid in one of the two types of water.
Why does salt water make stuff float than fresh water?
Salt water is denser than fresh water due to the dissolved salt molecules, which increases the water's mass. This higher density creates more buoyant force, enabling objects to float more easily in salt water compared to fresh water.
What is the same and different between fresh water and salt water?
Salt water contain dissolved sodium chloride; chemical and physical properties are different compared with fresh water.
Do fresh water ice and salt water ice melt the same?
yes
Will pressure be the same for salt water and fresh water be the same if dept is the same?
Not really. Salt water is denser(that's why you float better in the sea), so pressure will be greater.
Experiments using salt water and fresh water?
Experiments comparing the densities of salt water and fresh water can demonstrate how salinity affects the buoyancy of objects. Salt water is denser than fresh water due to the dissolved salt, causing objects to float higher in salt water compared to fresh water of the same volume. This phenomenon is demonstrated in experiments such as the floating egg or sinking and floating objects in different types of water.
