These variations in elevation affect climate—even for locations along the same latitudes. For example, El Paso has an average elevation of about 3,700 feet (1,128 m), which makes the temperatures there cooler than in cities at about the same latitude but that have lower elevations. Elevation also affects rainfall. Warm air holds more moisture than cool air. The mountains of West Texas receive more rainfall than the surrounding desert because moisture-filled air moving up the mountains is cooled. As the air becomes cooler, it is less able to hold moisture. The moisture in the rising air mass then falls as rain. For example, the Davis Mountains can receive up to 17 inches (43 cm) of rainfall. Only 24 miles (39 km) away, the Chihuahuan Desert is at a much lower elevation and receives less than 10 inches (25 cm) of rainfall a year.

• Deserts receive more rainfall than mountains if the desert is at a lower elevation.

• Elevation can affect the amount of average yearly rainfall.

• Cool air holds more moisture than warm air.

• The Davis Mountains receive large amounts of rainfall every year.
