Australian and North American Deserts- Habitats

Australian and North American Deserts will be the topic of discussion on Natures Talk Shows Habitats. Join the hosts as they discuss the differences between these amazing habitats. 

Chihuahuan Desert -- the largest desert in North America covering more than 200,000 square miles -- Most of it lies south of the international border. In the U.S. it extends into parts of New Mexico, Texas and sections of southeastern Arizona. Its minimum elevation is above 1,000 feet, but the vast majority of this desert lies at elevations between 3,500 and 5,000 feet.

Winter temperatures are cool, and summer temperatures are extremely hot. Most of the area receives less than 10 inches of rainfall yearly .While some winter rain falls, most precipitation occurs during the summer months.

This desert covers such a large area that it is difficult to characterize its geology, but limestone and calcareous soils are common
