Yes, there have been people in the Atacama since prehistoric times, especially the Atacameño tribe. The desert is almost in a state of perpetual drought even today but people continue to live there.
The longest drought on record occurred in the Atacama Desert in Chile, where it lasted for over 400 years. This region is one of the driest places on Earth, receiving less than 1 millimeter of rainfall annually in some areas.
The Sahara Desert is hotter than the Atacama Desert, it's larger than the Atacama Desert and it has more life, but the Atacama Desert is much drier. The Atacama Desert is the driest place on Earth, with an average of less than a millimetre of the rain.
During summer (January, February and March) the temperature fluctuates between 27°C (81°F) and a minimum of 16°C (61°F) at night. Hope this helps. The atacama desert is located in northern Chile and is the driest desert in the world!
Cacti are able to store water in their stems during times of rain to use during periods of drought.
Some deserts are naturally cool or even bitterly cold. The Patagonian Desert, Atacama Desert and Antarctica are examples of cold deserts. Other deserts are hot during the day but can become quite cool at night.
Each of the 26 major desert regions of the world is different when it comes to rainfall. It could range from 0 in the Atacama Desert to possibly 6-8 inches or more in parts of the Sonoran Desert during their annual monsoon.
so that they have a smaller surface area to lose water from
Succulents, such as cacti, are able to store water in their leaves and/or stems during times of rainfall that can keep them alive during drought.
Yes, there are some deserts that are cool or cold the year round such as the Patagonian Desert and the Atacama Desert. There are other cold winter deserts tat are hot during the summer but can be bitterly cold in the winter. The Gobi Desert and the Great Basin Desert are examples.
During a drought there is less rainfall.
Most desert plants have the same parts as plants from areas with more rainfall. Some, such as cacti, have lost their leaves and replaced them with spines. Some plants grow leaves during rainy seasons and then shed them during periods of drought. They may do this several times each year. Other plants allow their leaves to shrivel during drought and then spring back to life after a good rain.
Wildflowers adapt to desert habitats because they are able to withstand arid temperatures. They are also able to reproduce in harsh conditions.
