Mojave Desert needed for survival in the flora of the Sonoran Desert, which has an overlap in its major flora, such as the creosote bush ("Larrea tridentata"). The soil types in the Mojave and Sonoran deserts are mostly derived from volcano, specifically the areas in California.

As you go up the gradient of the desert, you will find more pediment and alluvial fan soil. In this areas, the flora is mostly
