Answer:
A. Areas at high elevations have cooler temperatures.
Step-by-step explanation:
Areas with high altitude or elevations have cooler temperatures because air molecules are less in the air at high elevation that decreases the gas pressure leading to low temperature.
Earth's surface absorbs heat and diffuses it into the atmosphere that warms up the earth's surface. Layers of the atmosphere in higher-altitude areas diffuses less heat and maintain the low temperature.
Hence, the correct option is "A. Areas at high elevations have cooler temperatures."
