Across
- 3. a change in temperature with distance
- 4. is 300 times more potent than CO2, also depletes the ozone layer
- 6. formed when ultraviolet radiation and oxygen interact to form ozone in the stratosphere
- 7. most abundant greenhouse gas, due to evaporation of water
- 9. move fast and vigorously, take up more space than their opposite, cool gas molecules
- 12. occurs when a planet absorbs more energy from the sun than it can radiate back to space; prevents the planet from cooling and from having liquid water on its surface(this answer contains an abbreviation)
- 13. measures air pressure
- 14. man-made greenhouse gases that are created from everyday activities that we don't stop to think about
- 15. in the past, CFCs were used in these common devices found in every home
- 17. weather occurs in this layer, it is the MOST dense
- 20. relationship where both variables are doing the opposite of each other
- 22. comes from the emission of livestock and agriculture and the emission of coal, natural gas, and oil
- 23. the burning of this item leads to a significant increase in CO2 emissions
- 24. home to the Northern and Southern lights
- 25. the accumulation of greenhouse gases such as methane, CO2, etc that warms the atmosphere and the surface of the Earth, making life possible.
Down
- 1. gas that composes most of the atmosphere
- 2. produced due to human activity, especially when fossil fuels are burnt
- 5. a global problem because the rising level of greenhouse gases due to hame activity
- 8. using fertilizers in this industry is a main cause of release of nitrous oxide
- 10. boundary between two atmospheric layers
- 11. have no natural source, but were entirely synthesized and invented by humans for uses such as aerosol propellants and cleaning solvents
- 16. is the COLDEST layer of the atmosphere because the layer above absorbs most heat
- 18. temperature increases as altitude decreases because of the ozone layer
- 19. formed from the volcanic eruptions that occur right after Earth formed(outgassing); contained sulfur, methane, and carbon dioxide
- 21. makes up approximately 1/5 of the atmospheric gases
