Geography
- The Atacama Desert is about 600 to 700 miles (1,000 to 1,100 km) long from north to south.
- It covers a total land area of approximately 104,741 sq km (40,442 sq miles).
- The range of the desert stretches from the Andes Mountains on the east to the Pacific Ocean on the west.
- From the coastline, the desert rises in elevation and has peaks in the eastern part reaching up to 6,000 meters above sea level.
Geography
Climate
- It is not only the highest desert in the world (16,570 feet), but also one of the coldest, with temperatures averaging between 0°C-25°C.
- Throught the summer season the temperatures are around 27°C during the day and 16°C (61°F) at night.

Top 3 animals in the atacama desert
Llmas: There are a lot of different types of llamas in the Atacama dessert, such as, vicuña, guanaco, Suri alpaca, Huacaya alpaca, and the domestic llama (Lama glama). A fun fact about them is that they typically live for 20 years, but some survive as many as 30 years. Herd animals, they are very social and live in large groups it is not uncommon to see herds of up to 100 llamas around the dessert.
Animals
Vicunas: The vicuña is one of the different types of llamas, a fun fact about them is that they are the smallest members of the camel family
Flamingos: In the Atacama Desert, you can find not one, but three different types of flamingos. The Andean, the Chilean and the James. A fun fact about these animals is that they have a special protection under there eyes that avoids getting a lot of salt water in there eyes

Atacama Desert Food Web
Atacama Desert Food Web
- The Atacama Desert:
- The food web is just like the typical food chain in most other areas. The desert's ecosystem consists of many species
- The Atacama Desert is almost without vegetation, except along slopes moistened by rain during the winter or in mesic valleys that bisect the otherwise dry desert.
- Fishes are very common in the Atacama Desert and a lot of animals that are living in the Atacama Desert eat fishes we could count that as a part of the food web.

Threats + Abiotic
abiotic
Some abiotic factors of the atacama desert are sand, little amount of water, and the amount of sunlight. The little amount of water, considering the Atacama desert is the driest place on the earth, makes it so very few organisms can live in the Atacama.
Threats
Threats
- Off-road vehicles
- dune buggies
- oil and gas production
- urbanization
- building towns and cities
