The Atacama Desert (Spanish: Desierto de Atacama) is a desert plateau located on the Pacific coast of South America, in the north of Chile.Stretching over a 1,600-kilometre-long (1,000-mile) strip of land west of the Andes Mountains, it covers an area of 105,000 km 2 (41,000 sq mi), [2] which increases to 128,000 km 2 (49,000 sq mi) if the barren lower slopes of the Andes are included.
The desert climate or arid climate (in the Köppen climate classification BWh and BWk) is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive.
Dallol features an extreme version of a hot desert climate (Köppen climate classification BWh) typical of the Danakil Desert. Dallol is the hottest place year-round on the planet and currently holds the record high average temperature for an inhabited location on Earth, where an average annual temperature of 34.6 °C (94.3 °F) was recorded ...
But as climate change makes heat waves more frequent, intense and long-lasting, experts say the increasingly severe conditions are testing some iconic desert plants known for their resilience ...
Tropical deserts are located in regions between 15 and 30 degrees latitude. The environment is very extreme, and they have the highest average monthly temperature on Earth. Rainfall is sporadic; precipitation may not be observed at all in a few years. In addition to these extreme environmental and climate conditions, most tropical deserts are ...
The climate is hyper-arid, extremely hot, sunny and dry year-round and there is virtually no plant life. The average high temperatures are above 40 °C (104 °F) for about 5 months and more in the hottest regions, and record high temperatures as high as 50 °C (122 °F) are highly possible during summer.
These regions feature a semi-arid climate and are less extreme than regular deserts. [34] Like arid deserts, temperatures can vary greatly in semi deserts. They share some characteristics of a true desert and are usually located at the edge of deserts and continental dry areas.
Today the Sahara region is mostly desert and the Sahel is characterized by savannah grasslands conditions. The African Humid Period was also characterized by a network of vast waterways in the Sahara, consisting of large lakes, rivers, and deltas. The four largest lakes were Lake Megachad, Lake Megafezzan, Ahnet-Mouydir Megalake, and Chotts ...
