What is an effect of increasing altitude on climate?

As altitude increases, the climate generally experiences cooler temperatures. This phenomenon occurs because air pressure decreases with altitude, leading to a reduction in temperature. The cooler temperatures at higher elevations result from the thinner atmosphere being less able to retain heat. Additionally, the lapse rate, which describes the rate at which temperature decreases with an increase in altitude, typically averages about 6.5 degrees Celsius for every kilometer ascended in the troposphere. Consequently, areas at higher altitudes, such as mountainous regions, are often significantly cooler than lower areas, even if they are at the same latitude. This understanding is essential in fields like meteorology, geography, and environmental science, as altitude can greatly influence local climates and ecosystems.
