A. Colorado Plateau
The Colorado Plateau is a high, arid region of the southwestern United States renowned for its layered sedimentary rock formations, deep canyons, and iconic national parks such as the Grand Canyon, Zion, and Arches.
B. Sierra Nevada–Great Basin transition zone
The Sierra Nevada–Great Basin transition zone is a geologic and ecological boundary region in eastern California and western Nevada where the high, granitic Sierra Nevada meets the arid, fault-block ranges and basins of the Great Basin.
C. Basin and Range Province
The Basin and Range Province is a vast geologic region of the western United States and northern Mexico characterized by alternating mountain ranges and arid basins formed through crustal extension.
D. Great Basin–Mojave transition zone
The Great Basin–Mojave transition zone is an ecologically and culturally significant desert region in the American Southwest where the Great Basin and Mojave deserts meet, characterized by mixed flora, fauna, and long-standing Indigenous presence.
E. Sonoran–Mojave transition zone
The Sonoran–Mojave transition zone is an ecologically rich region in the southwestern United States where the Sonoran and Mojave Deserts overlap, creating a unique blend of plant and animal communities from both desert ecosystems.
F. None of above. chosen
