Question

1. which statement best describes the relationship between relative humidity and air temperature as shown by the graph? relative humidity remains the same as air temperature decreases. relative humidity decreases as air temperature decreases. relative humidity decreases as air temperature increases. relative humidity increases as air temperature increases.

Explanation:

To determine the relationship, analyze the graph: the dashed line (air temperature) and solid line (relative humidity) have an inverse relationship. When air temperature increases (e.g., from midnight to noon/afternoon), relative humidity decreases, and vice versa. Let's evaluate each option:

• First option: Humidity doesn't stay same with temp decrease (graph shows change) → incorrect.
• Second option: Humidity increases (not decreases) when temp decreases → incorrect.
• Third option: As temp rises (e.g., morning to noon), humidity falls → matches the inverse trend.
• Fourth option: Humidity decreases (not increases) with temp rise → incorrect.

Answer:

C. Relative humidity decreases as air temperature increases.
