Why are days hot and night cold in rajasthan?

* Geographical Location: Rajasthan is located in the northwestern part of India, and it is surrounded by the Thar Desert. This desert region receives very little rainfall, and the temperatures can soar up to 50°C (122°F) during the summer months.

* Lack of Vegetation: The Thar Desert is a very arid region, and there is very little vegetation. This means that there is less moisture in the air, which can help to cool down the temperature.

* High Solar Radiation: Rajasthan receives a high amount of solar radiation throughout the year. This is due to the fact that the region is located close to the equator, and the sun's rays are more direct.

* Clear Skies: The skies over Rajasthan are usually clear, which allows the sun's heat to reach the ground more easily.

Nights are cold in Rajasthan due to the following reasons:

* Radiational Cooling: At night, the Earth's surface loses heat through radiation. This process is more pronounced in dry regions like Rajasthan, where there is less moisture in the air to trap the heat.

* Low Thermal Capacity of Sand: Sand has a low thermal capacity, which means that it takes longer to heat up during the day and cools down more quickly at night.

* High Altitudes: Some parts of Rajasthan are located at high altitudes, where the temperatures can be cooler even during the day.

The combination of these factors makes Rajasthan a very hot region during the day and cold at night.
