When ground water evaporates in the desert it can leave behind what?
Ground water can leave behind dissolved salts when it evaporates. As these salts accumulate they can have a very negative effect on desert plants or agriculture.
How does evaporation affects salinity?
Evaporation leaves salt behind. So as ocean water decreases, the percentage of salt increases, increasing salinity. As evaporation increases, rainfall also increases, thus it decreasing the salinity of ocean water.
How soluble salts are recovered from water?
Soluble salts can be recovered from water through methods such as evaporation, precipitation, or ion exchange. Evaporation involves heating the water to evaporate it and leave the salts behind. Precipitation involves adding a reactant to the solution to form insoluble salts that can be separated. Ion exchange involves passing the water through a resin that exchanges ions with the salts, allowing for separation.
When irrigation from sea water evaporates quickly what does it leave behind?
The residues are formed from salts.
Why does evaporation increase the desintiy of ocean water?
After evaporation the concentration of salts increase.
Does heavy evaporation increase or decrease salinity?
Heavy evaporation increases salinity because as water evaporates, it leaves behind dissolved salts, minerals, and other substances, which results in a higher concentration of salt in the remaining water.
Rain that falls does not taste salty?
You're right, it doesn't. Rain is water that has evaporated and then condensed. Evaporation means that things like salts will be left behind.
When water evaporates does the dissolved solid evaporate too?
No, when water evaporates, the dissolved solids are left behind. The process of evaporation only removes the water molecules, leaving the solid minerals or salts behind in a concentrated form. This is why evaporation is used to separate pure water from dissolved substances in processes like desalination.
How does the water leave the salt when it is evaporated?
When saltwater is heated and evaporates, the water molecules gain enough energy to escape as vapor, leaving salt behind. The water vapor rises and eventually condenses to form clouds or return as precipitation, leaving the salt behind in its solid form.
Major threats to the Nile River?
There are many but the major ones are regarding, Construction, pollution, evaporation and salinization. The links below will give further information. However the threat that is 'invisible' is the evaporation and salinization whereby the Nile water is bringing more salt to the fields of Egypt because of the increased evaporation of water from Lake Nasser. As the evaporation takes place salts are left behind in a more concentrated form and as the water irrigates the land there is an excessive accumulation of salts.
What type of desert results when moisture from soil evaporates and chemical salts remain?
A salt flat or salt pan is the type of desert that results from the evaporation of soil moisture, leaving behind chemical salts on the surface. These areas are characterized by a crust of salt or mineral deposits due to the high levels of evaporation in arid climates.
Is salinity the highest in the hot dry area?
Yes, salinity is higher in dry, hot areas because the high evaporation rate leaves behind salts dissolved in the water.
