Arid climates are characterized by low precipitation, typically receiving less than 10 inches (25 cm) of rain per year. These regions often experience high temperatures during the day and cooler temperatures at night. The lack of moisture leads to dry soil and limited vegetation, making it challenging for many plants and animals to thrive. Common examples of arid climates include deserts like the Sahara Desert in Africa and the Mojave Desert in the United States. In these areas, adaptations such as drought-resistant plants and animals that can conserve water are essential for survival.
