Phoenix Physical Geography Quiz: Quick Study Notes

Phoenix, Arizona, is renowned for its unique physical geography, nestled within a vast desert basin, shaped by significant rivers, and encircled by distinct mountain ranges. Understanding these features is key to appreciating the region’s climate, ecology, and human settlement patterns.

Key Geographical Features

Desert Basin Phoenix lies within the Sonoran Desert Biome, part of the Basin and Range Province characterized by alternating valleys and mountain ranges formed by extensional tectonics.
Rivers & Waterways The Salt and Gila Rivers are historically significant, with their flows heavily managed by dams (e.g., Roosevelt Dam) and canals (Salt River Project). The Central Arizona Project (CAP) also brings Colorado River water.
Surrounding Mountains The city is flanked by several ranges, including the McDowell Mountains (north), South Mountains (south), Estrella Mountains (southwest), and White Tank Mountains (west). These are typical fault-block mountains.
Climate & Ecology Phoenix has a hot desert climate (BWh Köppen classification) with extremely hot summers and mild winters. The Sonoran Desert supports diverse, drought-adapted flora, including saguaro cacti and palo verde trees.
