The Atacama Desert can attribute its astoundingly low precipitation to a combination of several “drying” factors: the subtropical high, a double rain shadow, and the cold ocean current running up the west coast of South America.
Atacama Salt Flat is the biggest salt deposit in Chile. It has a rough white surface below which there is a large salt lake. The salt flat has a surface area of 750,000 acres (300,000 km2), which can be appreciated in its entirety thanks to the clarity of the air.
A dazzling array of telescopes At 16,570 feet (5,050 meters) in elevation, the Atacama Desert plateau may be the best place in the world to spot the solar system's secrets. To the delight of amateur astronomers, the desert sees as many as 330 cloud-free nights each year.
10 Facts About The Atacama DesertDriest Desert in the World – Studies conducted by NASA have concluded that this desert located in northern Chile is in fact the driest desert in the world. ... Rainless (or just about) – Average rainfall in this region is about 1 mm per year.More items...
Its main tributaries are the San Pedro and Vilama rivers, which originate to the north of the salt flat. The volcanoes east of Salar de Atacama may be responsible for contaminating the incoming streams with salts.
In wet years, temporary lakes form and during the very hot, dry summers this water evaporates and minerals such as sodium chloride are left behind. After thousands of years, a salt crust has formed, creating salt flats.
5 Facts about the Atacama DesertIt is the driest desert in the world. ... It's the best place for stargazing. ... Atacama has the world's largest supply of sodium nitrate. ... Its soil is very similar to that on Mars. ... The oldest artificially mummified human remains are here.
The extreme aridity of the Atacama Desert in northern Chile has been associated with the uplift of the Central Andes and the subsequent blocking of moisture from the Amazon during the mid-Miocene (e.g., Alpers and Brimhall, 1988; Sillitoe and McKee, 1996).
Explanation: There is virtually no water in the Atacama so food cannot be grown there. Drinking water must be piped in from elsewhere and food trucked in from other areas. There is very little employment available except for some mining operations.
The Atacama is the driest place on earth, other than the poles. It receives less than 1 mm of precipitation each year, and some areas haven't seen a drop of rain in more than 500 years.
Cold Desert The average temperature of the site ranges from 0 °C to 30 °C. Whilst it's normal deserts drop in temperature at the night, the Atacama desert retains its cooler temperature throughout the day due to the influx of cold ocean air.
What is significant about the Atacama Desert? The three sub regions of South America are the Andes Mountains, the Amazon Rainforest, and the Eastern Highlands. The Atacama Desert is the driest place on Earth.

The quantity t 1/2 = ln 2 is called the half-life of an exponential decay, where =RC is the time constant in an RC circuit. The current in a discharging RC
Eg:- NaCl, CuCl2 etc. Acid + Base Salt + water. Sodium chloride is one of the best-known salt. One salt is known to almost everyone because of its widespread use in every day.
H2SO4 + NaOH NaHSO4 + H2O. 2. Basic or Alkali Salt – The salt formed by the partial neutralization of a strong base by a weak acid is known as a basic salt. They hydrolyze to form a basic solution. It is because when hydrolysis of basic salt takes place, the conjugate base of the weak acid is formed in the solution.
Types of Salt. 1. Acidic salt – The salt formed by partial neutralization of a diprotic or a polyprotic acid is known as an acidic salt . These salts have ionizable H + ion along with another cation. Mostly the ionizable H + is a part of the anion. Some acid salts are used in baking. For eg:- NaHSO 4, KH 2 PO 4 etc.
Double salt – The salts that contain more than one cation or anion are known as double salt. They are obtained by the combination of two different salts crystallized in the same ionic lattice. For eg:- Potassium sodium tartrate (KNaC 4 H 4 O 6 .4H 2 O) also known as Rochelle salt. 4.
In hydrolysis, the salt dissociates to form ions, completely or partially depending upon the solubility product of that salt. For a detailed discussion on acids, bases and salts and the reactions salts undergo like Hydrolysis of salts, check out our app BYJU’S – The Learning App. Take up a quiz on Salt Chemistry. Q 5.
It is present in large quantities in seawater, where it is the main mineral constituent . Salt is essential for animal life and saltiness is one of the basic human tastes.
The compound’s sodium chloride has very different properties from the elements sodium and chlorine. Saltwater contain s ions and is a fairly good conductor of electricity. This electrostatic force of attraction holds the ions together and a chemical bond is said to form between them.
