Explanation: To understand why Mussoorie is the correct answer, it is essential to consider the geographical and climatic factors that influence temperature. Mussoorie is a hill station located in the state of Uttarakhand, situated in the Himalayan mountain range. The elevation of Mussoorie plays a crucial role in its cooler climate. Hill stations are typically located at higher elevations, which results in lower temperatures compared to areas at lower elevations.
The Himalayan mountain range acts as a natural barrier, protecting Mussoorie from the hot and humid air masses that affect the plains. This geographical feature contributes to the cooler climate even during the summer months. The average temperature in Mussoorie during the summer ranges from 15°C to 25°C, making it a popular summer retreat for people seeking respite from the heat.
In contrast, Surat, located in the state of Gujarat, is situated at a low elevation and experiences high temperatures during the summer months. The average temperature in Surat during the summer can range from 30°C to 40°C, making it an unsuitable location for a cooler climate.
Jaisalmer, located in the state of Rajasthan, is part of the Thar Desert. It is known for its hot and dry climate, with temperatures often exceeding 40°C during the summer months. The desert environment and low elevation contribute to the high temperatures, making Jaisalmer an incorrect choice for a cooler climate location.
Therefore, Mussoorie stands out as the correct answer due to its elevation, geographical location, and the natural cooling effect provided by the Himalayan mountain range. This makes it a popular destination for those seeking a cooler climate even during the summer months.
