The main feature of a desert climate is its low precipitation levels. Deserts are characterized by receiving less than 10 inches (approximately 25 centimeters) of rain annually, resulting in arid conditions. This lack of moisture leads to significant temperature variations between day and night, with scorching heat during the day and cooler temperatures at night. Other features of desert climates include sparse vegetation and unique adaptations among flora and fauna to survive in such harsh conditions. While commonly associated with sandy landscapes and cacti, deserts can also include stone or gravel plains, showcasing diverse geographical features.
