Which climate zone includes deserts and is characterized by hot and dry conditions?

The climate zone that includes deserts and is characterized by hot and dry conditions is known as the Arid Climate Zone. This zone experiences very low rainfall, typically less than 10 inches (25 cm) annually, resulting in dry conditions that are suitable for desert landscapes. The temperatures in arid regions can vary greatly, with extremely hot days and cooler nights, depending on the specific geographical location.

Deserts found in the Arid Climate Zone, such as the Sahara and the Mojave, are defined not just by their lack of moisture but also by their distinct ecosystems that have adapted to survive in these harsh conditions. This zone is crucial in the study of climate and geography, as it helps illustrate how different environmental factors influence living organisms and human activities.

While the Polar Climate Zone features extremely cold temperatures and ice-covered regions, and the Tropical Climate Zone is known for its warm temperatures and significant rainfall, those do not pertain to the conditions of deserts. The Temperate Climate Zone, marked by moderate temperatures and seasonal rainfall, also doesn't include the characteristics of deserts, which are primarily found in arid conditions. Thus, the Arid Climate Zone is accurately identified as the climate characterized by deserts and hot, dry conditions.
