Deserts are characterized by extremely dry conditions and low humidity. This lack of moisture means that there is little water vapor in the air to trap heat. As a result, the heat that builds up during the day can easily dissipate at night, causing the temperature to drop rapidly.
In contrast, swamplands are characterized by high humidity and abundant water sources. The presence of water vapor in the air acts like a blanket, trapping heat and preventing it from escaping. This means that swamplands tend to retain their heat longer, resulting in slower cooling rates at night.
