An arid climate is characterized by low precipitation, typically receiving less than 250 millimeters (10 inches) of rain per year. This type of climate is often found in regions such as deserts, where evaporation rates exceed rainfall. The lack of moisture leads to dry conditions, which can result in sparse vegetation and limited water resources. Temperatures in arid climates can vary significantly between day and night. During the day, temperatures can soar, while nights can be quite cool. Examples of areas with an arid climate include the Sahara Desert and the Atacama Desert, both known for their extreme dryness and unique ecosystems.
