Which of the following climatic belts has the highest durnal temperature range?

The diurnal temperature range refers to the difference between the maximum and minimum temperature in a day. The climatic belt with the highest diurnal temperature range is the desert. Deserts are characterized by hot and dry weather conditions during the day and cold temperatures at night. This means that the diurnal temperature range in deserts is usually very high. During the day, the temperature in a desert can be very high, sometimes reaching up to 40-50°C, while at night it can drop to below freezing point. This large difference between the maximum and minimum temperatures makes the desert the climatic belt with the highest diurnal temperature range. In summary, the desert is the climatic belt with the highest diurnal temperature range, due to its hot and dry daytime temperatures and cold nighttime temperatures.
