What is the function of euthrophication?

Euthrophication occurs when the level of nutrients in a body of water - usually a lake - beocmes abnormally high. A common cause is that the lake is fed by a stream carrying run-off from agricultural land. The fertilisers in the run-off may cause excessive vegetation growth.

Which would freeze at a higher temperature the great salt lake or Lake Tahoe?

lake tahoe would freeze at a higher temperature

Lake water chemistry vs river water chemistry?

It all depends on the rate of flow... in a lake the water is calm, and the deeper the lake water is the less dissolved gas content changes- a lake has various layers, in it colder denser water stays at the bottom (below the warmer less dense water) - these layers tend not to mix so as the bottom layers of water have the dissolved oxygen removed from the water by biologic processes (decompostion of dead plant material by microbes, fish beatheing, etc.) the oxygen is depleated and the water becomes anoxic (oxygen deprived) this allows for the accumulation of biologic matter in vast quanties (think of fresh water swamps- the leaves don't decompose) after a good amount of sediment fills the lake up from various depositional episodes the bio-matter will become peat, and given even more time it can become coal or 'oil shale' like in certain ancient lake deposits out west (ex: Green River Basin, Piceance Basin of Colorado, etc.) In some extreme cases of super anoxic lakes the carbon dioxide levels are dangerously high (as in go down there and the acidity of the water will start to eat your scuba gear and you!) but this usually happens in lakes in volcanic systems (lake Nyos in Cameroon (Africa) is probably the most famous one in the world: the CO2 levels got so high in the lake (the gas seeped up out of the ground at the lakes bottom) than on August 21, 1986 when the water layers at the bottom of the lake were disturbed (probably an earthquake or land slide) the water column destabilized (like when you open a bottle of Coca-Cola after it has been shaken it explodes) releasing almost all of the CO2 gas dissolved in the lake… because CO2 gas much denser than regular air it poured down the valley that the lake was in suffocating 1700 people and countless live stock over a path of 15 miles…) also for lakes... generally rivers or streams pour sediments into them at high or moderate rates, once the speed of the water slows the suspended sediments drop out (larger grains (slits) at first then smaller (clays))this will cause a difference in stream vs. lake water chemistry The location of a lake is also very important if it is in the middle of a dranage system that does no release its water (like the Great Salt Lake of Utah or the Caspian Sea) the salt concentrations are very high, as rocks erode salt is released at a fairly constant rate, and if water is evaporating from said lake then the salt that is being put in it at very small amounts will become concentrated. for steams the chemistry the water is turbulent so lots suspended sediments an a fair amount of gasses like oxygen from the air are dissolved in it, also if the water is slightly acidic it can dissolve limestone (calcium carbonate). bicarbonate ions (HCO3-) and carbonate ions (CO32-) together make up almost 50% of total dissolved solids in average river water By the way this was a geology question, but chemistry has a lot to do with it … Make sure you find all of this data for yourself if you are doing a report, use wikipedia to point you in the right direction or use google scholar (this gives you real sources not blog garbage)- not saying this is or anything...

What is the pH and nature of lake water?

The pH and nature of any body of water can fluctuate wildly over a year. Rotting leaves and other organic debris, flood water flowing off farmland, streams flowing off limestone, industrial and domestic pollution, will all cause changes.

What happens to a lake's pH when acid rain falls on a lake that has limestone that contains calcium carbonate?

The lake's PH becomes lower or neutral(equal).

What will happen if plants and algae grow rapidly in a lake?

The lake will have heaps of plants and algae. they will then start dying and the "bodies" will rot which is a process that consumes oxygen, if too much organic mass rots it consumes all the oxygen in the water and everything in the lake dies- this process is called eutrification

What do you call a lake that has no oxygen at the bottom?

Dead lake.

When may eutrophication of a lake occur?

Eutrophication of a lake may occur when the lake acquires a high concentration of nutrients, especially phosphates and nitrates. This may occur naturally, or it may be caused by human activity such as fertilizers or sewage runoff. The high concentration of nutrients typically promotes excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of available oxygen, causing the death of other organisms, like fish.

What is meant by the term dry lake?

What Was the Aztec method of agriculture in shallow areas of the lake?

In shallow areas of a lake, the Aztecs would build up vegetation to form islands. These were called chinampas.

When excess fertilization drains into a lake what may occur?

eutrophicationeutrophicationFertilizer in a lake helps algae grow. Up to a certain point, that is good. The algae turns carbon dioxide into oxygen and adds oxygen to the water. However, after that point, the algae covers the lake. Oxygen from the air can not get to deeper water. Dead algae falls to the bottom of the lake and decomposes. The process of decomposing uses up oxygen. The amount of oxygen in the lake drops below the point where fish can survive. Thus, over fertilization leads to a fish kill.
