Date of TEST: ________________________
Be sure to study ALL of your NOTES, Openers, any activities we have done in class and the pages in the
textbook we have read.
1. What percentage of the Earth’s atmosphere is made up of nitrogen gas? Carbon Dioxide gas?
2. Study your Ocean Acidification Activity. Be able to read the graph and answer questions on it.
3. What is biogeochemical cycling? Why is it important to the biosphere?
4. What is the correct order of processes that are involved in the formation of sedimentary rocks?
Terms to use: deposition, erosion, weathering, cementation and compaction.
5. What energy sources drive the rock cycle?
6. Sedimentary rocks are primarily formed by processes powered by what energy source? Explain.
7. Metamorphic and igneous rocks are primarily formed by processes powered by what energy source?
Explain.
8. What are minerals? What are rocks?
9. Explain how humans are affecting the carbon cycle?
10. What are the three types of rocks?
11. Biological systems do not use up matter, they transform it. Explain what this statement means.
What law does it satisfy?
12. How are the three types of rocks classified? Based on what?
13. What do coal, oil and natural gas have in common?
14. What are some processes that decrease the amount of carbon dioxide in the atmosphere?
15. What are some processes that increase the amount of carbon dioxide in the atmosphere?
16. What is the role of decomposers?
17. What is transpiration?
18. What are sphere interactions? If trees are cut down in an ecosystem would that affect other spheres?
Why or why not?
19. Know the water cycle and all the possible ways water can move between spheres. Draw a picture of
it.
20. Know the rock cycle and all the possible ways rocks can change, how they form and move from one
place on the rock cycle to another. Draw a picture of it.
21. Know the different spheres that make up earth’s system.
22. What do greenhouse gasses, such as CO2, do to the Earth?
23. How does the transfer of solar energy throughout an ecosystem start? Explain.
24. What is a closed system? What is an open system? What would Earth be an example of? Explain.
25. Why do organisms need nutrients? Why are the biogeochemical cycles so important to the
biosphere?
26. What is the difference between a carbon source and a carbon sink?
27. What is an ecosystem?
28. Know the carbon cycle. Draw and image.
29. Know the difference between photosynthesis and cellular respiration. Which is a carbon
source/sink?
