A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid.
The cold Humboldt Current and the Pacific Anticyclone are essential to keep the dry climate of Atacama Desert. The average rainfall in the Chilean region of Antofagasta is just 1 mm per year. Some weather stations in the Atacama have never received rain. Evidence suggests that the Atacama may not have had any significant rainfall from 1570 to ...
The Atacama Desert in northern Chile is one of the driest places on Earth, but swaths of its usually barren sand are currently carpeted with a colorful bloom of white and purple flowers.
The geography of South America contains many diverse regions and climates.

The Llano de Chajnantor is a 5,100-metre-high (16,700 ft) plateau in the Atacama Desert, about 50 kilometres (31 mi) east of San Pedro de Atacama. The site is 750 metres (2,460 ft) higher than the Mauna Kea Observatory and 2,400 metres (7,900 ft) higher than the Very Large Telescope on Cerro Paranal.
The Atacama Desert is one of the driest on Earth. [64] The arid climate is due to subsidence of air within the South Pacific Anticyclone, which extends to the Andes. [65] Owing to the dry climate, [66] snow cover on Licancabur is ephemeral [2] and there are no glaciers. [66]
