Science Help (Weather)!?

Question

Okay....I just ned a little help with these two questions. If you could explain your answer that would be GREAT! but you dont have to.

Please and Thanks,

Ellie Mae

1. Air at higher temperatures can hold ____ water vapor than air at lower temperatures.

A. More or less (depending on the dew point)

B. Less

C. More

D. The same amount

2. One place where ___ form is along fronts.

A. High pressure systems.

B. Temperate Zones

C. Isotherms.

D. Low pressure systems.

Answer 1

The answer is,

(1) C,

(2) D.

Answer 2

1) Air at higher temperatures can hold ____ water vapor than air at lower temperatures.

C. More

Reason: It is widely believed that warm air can hold more water vapor than cooler air because warm air is less dense than cool air, therefore there should be more space than water. However, it appears that this is not the case. The fact is, warm air increases the rate of evaporation, this way there would be more water vapor in the air.

2) One place where ___ form is along fronts.

D. Low pressure systems.

Reason: High pressure systems are not associated with fronts. A front is a large scale boundary between two air masses (such as cold and warm air). Temperate zones are types of climate and fronts have no affect on them. Isotherms are lines of equal temperature on a weather map. Low pressure systems are typically associated with any of four different types of fronts (cold, warm, occluded and stationary).
