Dry climates are characterized by low precipitation, typically receiving less than 10 inches of rain per year. These regions often experience high temperatures during the day and cooler nights, leading to significant temperature fluctuations. Common vegetation includes drought-resistant plants like cacti and shrubs, which have adapted to conserve water. Examples of dry climates include deserts such as the Sahara in Africa and the Mojave in North America. These areas can be found on every continent and are often associated with unique ecosystems. The lack of moisture affects soil quality and limits agricultural activities, making water conservation crucial for survival.
