Factors influencing the salinity of the lake, factors affecting the salinity of the lake

1.Evaporation, 2Make-up water, 3With or without an exit, 4Other factors, such as the impact of subsurface runoff.

Solar radiation, river runoff.

Factors influencing lake salinity include precipitation, evaporation, runoff, solubility, etc. The greater the rainfall, the lower the salinity. The more evaporation, the higher the salinity.

The more land runoff that flows into the estuary area, the lower the salinity. When the warm current flows through the lake area, the evaporation is high, and the solubility of salt is large, so the salinity is high.

The main factors affecting the salinity of seawater vary with the latitude of the sea area, which is mainly affected by latitude, river, sea contour and ocean current.

In the high seas or oceans, the main factors that affect salinity are precipitation, evaporation, etc. In coastal areas, salinity is mainly influenced by river runoff.

From low to high latitudes, the salinity of seawater depends mainly on the difference between evaporation and precipitation. Evaporation concentrates seawater, while precipitation dilutes seawater. In the sea where rivers are emptied, the salinity of the seawater is usually relatively low.

In addition, the amount of ice accumulation and ice melt in high-latitude seas (the salinity of the seas where ice accumulation occurs is relatively high; The salinity of the sea is also affected by the lower salinity of the sea where the ice melts), the degree of closure of the sea area (the higher the degree of closure of the sea area, the higher or lower the salinity), and the exchange capacity of seawater with nearby seawater. Each factor has a different time variation space, so the salinity of the sea water is also different time change space.

The influencing factors of lake salinity include precipitation, evaporation, runoff, solubility, etc. The greater the precipitation, the lower the salinity; The greater the evaporation, the higher the salinity; The more land runoff is injected into the estuary, the lower the salinity. The evaporation of the warm current flowing through the lake area is large, and the solubility of salt is also large, so the salinity is high.

The salinity of seawater varies according to the latitude and location of the sea area, and is mainly affected by latitude, river, sea contour, ocean current, etc.

In the open sea or ocean, the main factors affecting salinity are precipitation, evaporation, etc.; In near-shore areas, salinity is mainly affected by river runoff.

From low to high latitudes, the salinity of sea water depends mainly on the difference between evaporation and precipitation. Evaporation concentrates seawater, and precipitation dilutes it. In areas where rivers feed into the sea, the salinity of the sea is generally low.

In addition, the amount of ice formation and melting in high-latitude sea areas (the salinity of sea areas with icing phenomenon is high; The salinity of seawater can also be affected by the low salinity of the sea area where ice melt occurs), the tightness of the sea area (the stronger the closure of the sea area, the higher or lower the salinity), and the amount of seawater exchanged with the nearby sea area. Each factor has different changes in time and space, so the salinity of seawater also has differences in time and space.

The most salinity lake in the world is the Dead Sea.

Located on the border of Israel, Palestine and Jordan, the Dead Sea is the lowest lake in the world, with a surface of one meter above sea level. The deepest part of the lake is meters, and the deepest part of the lake bed is meters above sea level. It is also the third most salinous water body on the planet, second only to the Don Juan Pond in Antarctica, which has the second highest salinity, and the first Gaet, which is located in Ethiopia'ale pond。

Located in the Great Rift Valley between Israel, Palestine and Jordan, the Dead Sea is 86 kilometers long from north to south and 5 to 16 kilometers wide from east to west, with the deepest point being meters. The shores of the Dead Sea are the lowest point on earth that has been exposed to land, and are known as the "navel of the world". From afar, the Dead Sea resembles a two-tailed fish.

In the sunlight, the sea looks like an ancient bronze mirror. After the 1967 Arab-Israeli war, Israeli forces occupied the entire West Bank. The Dead Sea contains a high concentration of salt, twice that of ordinary seawater, so that there is no living life in the water, and even on the land along the coast of the Dead Sea, there are few organisms other than aquatic weeds.

This is one of the reasons why people named it the Dead Sea.

The Dead Sea is disappearing. According to the World Environmental Protection Organization, the water level in the Dead Sea is decreasing at a rate of one foot (about 1 meter) per year, and the salt concentration in the Dead Sea is greatly increasing as the amount of water decreases.

Salt lakes are formed because the water is saturated with salts.

The climate is arid, the precipitation is less than the evaporation, and the salts in the lake water are precipitated and deposited on the bottom and shore of the lake after they reach a saturated or supersaturated state.

The formation process of the Gillette salt lake is as follows:

Carbonate deposition stage: The solubility of carbonate is the smallest among salt minerals, so carbonate minerals are first crystallized during the concentration salinization of lake water. The carbonate deposition stage is characterized by the deposition of alkaline salts, so the saltwater lakes that are currently receiving carbonate deposition are called the alkaline lake acid deposition stage

With the further concentration and salinization of carbonate sedimentary lake water, sulfate with high solubility begins to crystallize after carbonate, and the sulfate deposition stage is characterized by the deposition of bitter salts, so the saltwater lake that is currently receiving sulfate deposition is called bitter lake.

Chloride deposition stage: After the deposition of sulfate reed, the lake water is further concentrated and the salinity exceeds 24 25, and the chloride begins to crystallize, and the appearance of chloride marks that the salt lake has entered the final sedimentation stage, and the saltwater lake that is currently receiving chloride deposition is called a salt lake. <>

In general, freshwater lakes are mostly found in humid areas, while saltwater lakes are mostly found in arid areas. Freshwater lakes have both the inflow and outflow of water, while the saltwater lakes have only the inflow of water and no outflow. When the salinity of the water in the lake is more than 1%, it can be called a brackish water lake (brackish water lake).

The water contains a lot of minerals, and the water evaporates and the minerals settle down, and over the years it becomes the saltwater lake it is today. It is caused by the natural conditions of continuous evaporation and large sinking of minerals due to the water flowing into the lake. The temperature is very high, and the higher the temperature, the greater the evaporation.

There are many sunny days, strong sunshine, and little rain, and the amount of water replenished is minimal, and the amount of minerals deposited at the bottom of the lake is increasing, and the salinity is increasing. Of course, if the lake water cannot be discharged with a certain amount of water, the saline-alkali components cannot be carried out of the lake with the solution, resulting in an increase in salinity!
