The Thar Desert experiences extreme temperature variations between day and night because of the high daytime temperatures which cause rapid cooling once the sun sets. This significant difference is due to the desert's dry conditions and lack of moisture to retain heat. Interestingly, such temperature swings are typical of desert climates, where the absence of cloud cover allows for swift heat loss at night.

Variation in Temperatures in the Thar Desert
The Thar Desert, located in northwestern India and eastern Pakistan, experiences significant temperature variations between day and night. The primary reason for this phenomenon is attributed to its climatic and geographical characteristics.
High Temperature During the Day
- During the day, the Thar Desert receives intense solar radiation due to its clear skies and minimal vegetation.
- The sandy soil absorbs heat quickly, leading to extremely high temperatures that can soar above 50°C (122°F).
Rapid Cooling at Night
- As night falls, the absence of cloud cover allows the heat absorbed during the day to escape rapidly into the atmosphere.
- The desert's dry air, having low humidity, does not retain heat well, resulting in a sharp drop in temperature.
Limited Thermal Retention
- The lack of moisture in the air means there are fewer water vapor particles to hold onto heat.
- This results in a dramatic contrast, where daytime temperatures are scorching, while nighttime temperatures can plummet to near freezing.
Conclusion
The combination of high daytime temperatures and the rapid loss of heat at night leads to significant temperature variations in the Thar Desert. Understanding this phenomenon is crucial for those studying desert climates and their ecological impacts.

Similar Class 9 Doubts

Read the source given below and answer the questions that follow:There are six major controls of the climate of any place. They are: latitude, altitude, pressure and wind system, distance from the sea (continentality), ocean currents and relief features.Due to the curvature of the earth, the amount of solar energy received varies according to latitude. As a result, air temperature generally decreases from the equator towards the poles. As one goes from the surface of the earth to higher altitudes, the atmosphere becomes less dense and temperature decreases. The hills are therefore cooler during summers. The pressure and wind system of any area depend on the latitude and altitude of the place. Thus, it influences the temperature and rainfall pattern. The sea exerts a moderating influence on climate: As the distance from the sea increases, its moderating influence decreases and the people experience extreme weather conditions. This condition is known as continentality (i.e., very hot during summers and very cold during winters). Ocean currents along with onshore winds affect the climate of the coastal areas. For example, any coastal area with warm or cold currents flowing past it, will be warmed or cooled if the winds are onshore.Finally, relief too plays a major role in determining the climate of a place. High mountains act as barriers for cold or hot winds, they may also cause precipitation if they are high enough and lie in the path of rain bearing winds. The Leeward side of the mountains remains relatively dry.Q. As one goes from the surface of the earth to higher altitudes, the _________ becomes less dense and temperature decreases.
