Overview The following are three of North America's major hot and dry deserts, all of which are situated in the southwestern United States and northern Mexico. The Mojave Desert, located mostly in southeastern California, is North America's hottest desert. It has a total size of 22,000 square miles (57,000 km2). The Sonoran Desert, found in southern Arizona and northwestern Mexico, is North America's largest desert. It has a total size of 5 million acres (20,000 km2). The Chihuahuan Desert, located in south-central Mexico and north-western Texas, is North America's third largest desert. It has a total size of 4 million acres (16,000 km2).
Geographically, the Mojave and Sonoran deserts are part of the Great Basin, while the Chihuahuan desert is part of the Colorado Plateau.
They share many similar features, such as sparse vegetation, large sand dunes, steep canyons, and arid climate. However, the Mojave and Sonoran deserts also have some differences. For example, the Sonoran Desert is home to more species of plants and animals than the Mojave Desert. In addition, the Chihuahuan Desert is cooler than both of its neighboring deserts due to its location at higher elevation.
The deserts were created over time by the movement of tectonic plates.
Because of the severe environment, there is relatively little biodiversity in the desert, regardless of whether the temperature is extremely hot or extremely cold. The Mojave Desert is one of the most well-known deserts in the world, and it is located in the United States. This region includes much of California, Nevada, Arizona, and Utah. Scientists have discovered only 7% of the species that are present in the Mojave Desert.
The majority of the species found in the desert are small insects that live on plants. There are also a few species of reptiles and mammals in the desert. However, because of the harsh climate, many animals find it better to be alive than healthy. This is why so many endangered species are found in the desert -- because they are able to survive in such a hostile environment.
People have been living in the desert for thousands of years using natural resources around them. They have learned how to adapt to the conditions here by making tools out of rock, hunting game with bow and arrow, and growing crops where it isn't too hot or too cold. Over time, these people have developed cultures unique to the desert; for example, Native Americans used to live in Mexico City but were forced out by high temperatures and pollution. Today, these people have been replaced by immigrants from other parts of the world who have chosen to live in the desert because of its freedom and lack of crime.
The Mojave Desert is an arid area of southern California and parts of Nevada, Arizona, and Utah in the United States. It was given the name Mojave after the Mojave people. The Mojave Desert covers more than 25,000 square miles (65,000 square kilometers) and is part of the North American Desert, which also includes the Sonoran, Great Basin, and Chihuahuan deserts.
Geographically, the Mojave Desert is divided between San Bernardino and Inyo counties in California and Nye and Mohave counties in Nevada. Although most of the desert is in California, a small portion is in Nevada. Geographically, the desert extends from the border with Mexico near the town of Crestline to just south of Barstow. However it does not include the Lake Mead region, which is part of Las Vegas Valley.
The Mojave Desert has some of the lowest average elevation of any major geographical area in the United States. Its highest point is Searle Ridge at 10,720 feet (3,220 m), while its lowest point is 1,800 feet (550 m) above sea level. The desert receives very little precipitation, with an annual average of less than eight inches (200 mm). Most years, there are only two days with measurable rainfall: a morning thunderstorm in July and another in October.
Most of the desert is made up of hard-packed dirt called loam, which is good for growing crops. There are several small lakes within the desert.
