Elevation determines how dense the air is and how much heat energy the air can hold. The correct option is D.
<h3>How does elevation affect climate?</h3>
Elevation affects climate such that the higher one goes, the less dense the air is.
The less dense the air in a place is, the lower the amount of heat energy the air can hold.
This is why elevated places have cooler atmospheres when compared to sea levels.
Also, the higher one climbs, the cooler it becomes.
