Answer:
Higher elevations experience cooler temperatures compared to lower elevations.
Explanation:
Elevation helps to determine the temperature of an area through relationship between availability of air and the pressure. The higher the elevation, the lower the availability of air which in turns leads to lower pressure.
This lower pressure influences the temperature of that point to be cooler. At same time, the lower the elevation and all things being equal, the hotter the temperature.
