20. Elevation above sea level and temperature are negatively correlated variables. Which of the following statements describes the relationship between the variables?
Answer: D
As elevation increases, temperature decreases.
The relationship between elevation and temperature indicates that higher elevations typically correspond to lower temperatures, demonstrating a negative correlation between these two variables.
A) As elevation decreases, temperature decreases
This option is incorrect because it suggests that lowering elevation results in a drop in temperature, which contradicts the established negative correlation. In reality, as elevation decreases, temperature tends to increase.
B) As elevation decreases, temperature remains the same
This option is also incorrect. While temperature may vary less dramatically at certain low elevations, it does not remain constant as elevation decreases. Generally, temperature tends to increase with decreasing elevation.
C) As elevation increases, temperature increases
This statement is incorrect as it contradicts the established negative correlation between elevation and temperature. As elevation rises, the temperature does not increase; instead, it decreases.
D) As elevation increases, temperature decreases
This statement accurately describes the negative correlation between elevation and temperature. As one ascends to higher elevations, the temperature generally drops, making this option the correct choice.
Conclusion
The correct answer, D, clearly illustrates the negative correlation between elevation and temperature, where increased elevation corresponds with decreased temperature. All other options either misrepresent the relationship or contradict the fundamental principle of how temperature changes with elevation.
