Answer:
The temperature difference between mountains and deserts is primarily due to variations in elevation and geographical factors. Mountains are at higher elevations, where the air is thinner, causing it to cool rapidly as it rises. Deserts, on the other hand, are often at lower elevations and receive intense sunlight, resulting in high temperatures. Additionally, mountains can block or redirect prevailing winds, leading to differences in local climate patterns. These factors collectively contribute to the temperature contrast between mountains and deserts.
