Death Valley: Desert Biome Survival

描述

Death Valley is the largest National Park and the most extreme desert biome in the lower 48 states. Its hot, dry landscape and climate force plants and animals into extreme adaptations for survival. Some animals such as kangaroo rats recycle their own moisture, while the jackrabbit has developed huge ears that wick away heat. While Death Valley's average annual rainfall is 1 ½ inches, Devil's Hole below the valley is one of the largest aquifers in the U.S. After eons of tectonic forces and wind erosion, the valley can be transformed by flash floods that create magnificent alluvial fans and rare bursts of dazzling wildflowers across jagged terrain. This program reveals a land of fascinating paradoxes.
