.
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. Contains ozone layer - temperature increases upward due to oxygen - which absorbs UV radiation

2. 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

5. Decreases upward to altitude of 10-15 km due to increase distance above main mass of earth - which absorbs sunlight and reradiates it as heat

6. Ratio of observed absolute humidity divided by sbsolute humidity at dew point

7. Occurs when rising air expands without change in heat content. Whenever an air mass expands - the available heat is distributed over a larger volume so the air becomes cooler.

8. 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

10. 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.
