During sunny days we prefer going to hill stations. But even during the morning, the hill stations are cool. But they must be hot as they are closer to the sun than the land at sea level. Why is that so?

The temperature typically decreases as altitude increases. This is due to the decrease in air pressure and density at higher altitudes, which results in less heat being trapped in the atmosphere.
In the troposphere, the lowest layer of the Earth's atmosphere, temperature decreases at a rate of approximately 6.5°C per kilometer of altitude. This is known as the environmental lapse rate.
At the top of the troposphere, known as the tropopause, temperatures can range from -55°C to -80°C, depending on the location and time of year. This is due to the decrease in air pressure and lack of heat-trapping greenhouse gases at this altitude.
In the stratosphere, the layer above the troposphere, temperature increases with altitude due to the presence of ozone. This is known as the stratospheric temperature inversion.
The variation in temperature at different altitudes is primarily due to the varying levels of heat absorption and retention in the Earth's atmosphere. Factors such as air pressure, air density, and the presence of greenhouse gases all impact temperature at different altitudes.
