6. Property measuring particle closeness is density.
7. Envelope of gases is atmosphere.
8. Water in gaseous state is water vapor.
9. Gas with three oxygen atoms is ozone.
10. Measure of distance above sea level is altitude (not in word - bank).
11. Layer where weather occurs is troposphere.
12. Layer burning up meteoroids is mesosphere (not in word - bank).
13. Harmful substance in environment is pollutant.
14. Second most abundant gas is oxygen.
15. Fourth most abundant gas is carbon dioxide.
16. Rain from pollutants is acid rain.
17. Third most abundant gas is argon.
18. Pollutants mixed with fog is smog.
