.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Ratio of observed absolute humidity divided by sbsolute humidity at dew point

17. If air cools to the temp at which its relative humidity is 100% - the water saturated air is still invisible. If it cools further - it will have more ater vapor than it can hold and some of the water will condense into tiny water droplets - to form c

18. Low pressure system. When an air mass near the ground is heated - the air molecules vibrate faster - cause the air mass to expand and its density to decrease. With a lower density than the surrounding air - the mass rises to create a low pressure reg

19. Lowest layer. Where all weather phenomena occur. Extends to altitude of 10 to 15 km - contains about 90@ of mass of atmosphere - including about all water vapor.

20. High pressure system. when cool air in the upper atmosphere has higher density than its surrounding - creating high pressure system. It moves twd the ground - so air moves way from the high pressure system near earth's surface
