Atacama Desert in Chile which receives less than 1 inch of rainfall per year.

The Atacama desert. It's in the rain shadow of the Andes. It contains deposits of highly soluble nitrates, which even a small rainfall would have washed away long ago. But the driest place on Earth is the Dry Valleys in Antarctica. They get some snow and, occasionally, in the middle of summer, a little rain. But humidity is around 2% most of the time. The reason is, katabatic winds descending from the ice cap have had almost all the water wrung out by the low temperature of the ice cap. Humidity means how much water vapour is in the air compared with the maximum amount it can hold. The warmer the air, the more water vapour it can hold without condensation. So if you take a sealed jar of moist air, relative humidity 100% and warm it up, the relative humidity decreases, even though the amount of water vapour and air both stay the same. That's how dehumidifiers work. Cool the air down so water vapour condenses into a container, then use the heat you've extracted to warm it up again, minus the water.

Precipitation means rain, snow, hail, sleet or any other form of water landing on the ground. Deserts are defined as areas with very low precipitation (less than 10 inches per year) with places like Death Valley, USA and the Atacama Desert in Chile being particularly dry.
However (and most surprisingly) the driest place on the planet is in Antarctica - the so-called Dry Valleys of Antartica near McMurdo Sound are not covered by snow (yet they are so cold that any snow that did fall would certainly not melt) and receive NO rainfall at all.
It has been estimated that there has been no precipitation there for at least 2,000 years and possibly for as long as 2 million years.
There is so little water there that the normal processes of decay do not occur - there is a body of a seal there that died perhaps hundreds of years ago and which is perfectly mummified.

easily the Atacama wasteland is the 2d driest spot on earth formally, regardless of the incontrovertible fact that there are places interior the Atacama that have by no ability had any recorded rainfall (in many years and many years). Antarctica is formally the driest place on earth, regardless of the incontrovertible fact that i think that probable in user-friendly terms refers to specific aspects of Antarctica, like the South Pole, as suggested under. Antarctica is unquestionably the driest continent on earth, averaging decrease than 2 inches of precipitation consistent with 12 months. that's generally in comparison with dying Valley, California, which gets approximately 2 inches of rain a 12 months. linked is a reference which argues, from archives over various many years of length, that the South Pole is extensively drier than the Atacama, or a minimum of the region the place the telescopes are stationed in Atacama, which became chosen because of the fact it became very dry and hence a good place for astronomical observatories (water vapor absorbs some wavelengths of sunshine). As this reference states, "Of the three web pages, South Pole has by ability of far the backside PWV, for the time of Austral summer season as properly as wintry climate. in fact, the seventy 5th percentile fee for the wetter a million/2 of the 12 months on the South Pole is decrease than the twenty 5th percentile fee for the drier a million/2 of the 12 months at Mauna Kea or Atacama." In otherwords, the "wettest" component of the 12 months on the South Pole remains extensively drier than the driest component of the 12 months at Atacama.

Even though no precipitation was ever witnessed in the Atacama desert, there are places in Antarctica that haven't had any precipitation for millions of years.
