Final answer:
The elevation increases as the average annual temperature decreases due to reduced air pressure, atmospheric inversion, changes in wind patterns, and increased humidity.
Step-by-step explanation:
The elevation increases as the average annual temperature decreases due to a few factors. One of the main factors is reduced air pressure. The density of air decreases with altitude, so as you go higher in elevation, the air pressure decreases. Another factor is atmospheric inversion, which is a phenomenon where warm air traps cooler air near the surface. This can lead to lower temperatures at higher elevations.
Additionally, changes in wind patterns can affect temperature and elevation. Wind blowing from high to low elevations can cause the temperature to decrease as it moves uphill. Lastly, increased humidity can also contribute to a decrease in temperature at higher elevations. Warm air can hold more moisture than cold air, so as the humidity increases, it can lead to cooler temperatures.
