Answer Key

Part A: Multiple Choice

1. b) Condensation
2. b) Barometer
3. d) Cumulonimbus
4. b) The long-term average of weather patterns in a specific area
5. b) Troposphere

Part B: True or False

6. True
7. True
8. False
9. True
10. False

Part C: Short Answer (sample responses)

11. The water cycle is the continuous movement of water on, above, and below the surface of the Earth. It includes processes such as evaporation (water turning into vapor), condensation (vapor cooling into liquid), precipitation (water falling back to Earth), and collection (water gathering in rivers, lakes, and oceans).

12. Weather refers to the short-term atmospheric conditions in a specific place and time (e.g., today's temperature and conditions), while climate refers to the long-term average of weather patterns over a significant period (e.g., average temperatures in a region over many years).

Part D: Essay Question (sample points)

13. Human activities, such as burning fossil fuels, have increased greenhouse gas emissions, leading to climate change. For example, higher CO2 levels contribute to global warming, resulting in rising sea levels and extreme weather events like hurricanes. Deforestation also affects local climates and weather patterns by disrupting ecosystems.
