The Sonoran Desert lies directly west of the Mojave Desert, covering parts of California, Arizona, and Mexico.

The Sonoran Desert is located directly west of the Mojave Desert, extending into southwestern Arizona, southeastern California, and parts of Mexico. This desert is known for its diverse plant life, including the iconic saguaro cactus, which is absent from the Mojave. The Great Basin Desert lies to the north of the Mojave, while the Chihuahuan Desert is farther to the southeast, and the Atacama Desert is in South America, not directly related to the Mojave Desert’s location. The Sonoran Desert has a slightly warmer climate and different ecosystem compared to the Mojave Desert.
