Location and Characteristics of the Simpson Desert
The Simpson Desert is located in the central part of Australia, covering parts of three states: South Australia, Queensland, and the Northern Territory.

What is a Desert?
A desert is a region that receives very little rainfall, usually less than 250 millimeters per year. Deserts are characterized by their arid climate and sparse vegetation. They can be found in many parts of the world, from the Sahara in Africa to the Gobi in Asia. Despite their harsh conditions, deserts are home to a variety of plants and animals that have adapted to the extreme environment.
Neighboring Deserts to the Simpson Desert
While the Simpson Desert is a vast and isolated region, there are several neighboring deserts that share similar characteristics. These include the Great Victoria Desert, the Sturt Stony Desert, the Tirari Desert, and the Strzelecki Desert. Each of these deserts has its own unique landscape and ecosystem.
The Great Victoria Desert
