Question
Give a geographical reason:
The diurnal range of temperature is more in desert areas.
Short Note
Solution
The diurnal range of temperature is more in desert areas because -
- Deserts get hot during the day but cool down rapidly during the night. The main reasons for the temperature fluctuation between day and night are the lack of humidity and cloud cover.
- Because of water's relatively high specific heat, humid air takes longer to warm or cool, while the air on land warms or cools more quickly.
- Because desert areas receive a large amount of sunlight, the temperatures can get very high, but during the night the dry air cools quickly.
- The lack of cloud cover overhead allows the warmer air to rise into the atmosphere while cooler air settles in its place.
- Basically, desert temperature varies so much because there are less moisture and cloud to keep the heat there.
