A significant characteristic of an arid climate is extremely low rainfall combined with high evaporation rates, leading to dry conditions.

Arid climates are defined by very low rainfall and high evaporation rates. This combination results in dry, desert-like conditions where water resources are scarce, and vegetation is limited. With minimal precipitation, the soil has little moisture, making it difficult for most plants and animals to survive without adaptations for conserving water. High temperatures and intense sunlight further increase evaporation, causing water sources like rivers, lakes, and reservoirs to dry up quickly. These conditions are common in regions like deserts, where the environment supports drought-resistant plants, cacti, and shrubs, all adapted to thrive in extreme, dry climates.
