6. T/F Wind, water, and planting trees all allow erosion to take place. A 100

7. False A 100

8. T/F Growing tree roots, rain, and freezing and thawing ice all cause physical weathering. A 200

9. True A 200

10. Which would chemically weather faster: marble gravel or quartz gravel? A 300

11. Marble gravel A 300

12. Are the particles that make up soil normally all the same size or different sizes? A 400

13. Different sizes A 400

14. What breaks large rock into smaller pieces? A 500

15. Physical Weathering A 500

16. Weathering of rocks into smaller particles is a very fast process. True/False B 100

17. False B 100

18. What is the difference between physical and chemical weathering? B 200

19. Rocks are physically weathered by breaking them into smaller pieces. Rocks are chemically weathered when compounds in the rock react chemically with another chemical and this weakens the rocks. B 200

20. Wind blowing over a field is a cause of chemical weathering? True/False B 300

21. False B 300

22. What are three components of soil? B 400

23. Gravel, sand, and organic material B 400

24. Erosion takes place when ________ B 500

25. Rocks and soil are transported from one place to another. B 500

26. The tool used to separate the soil to analyze the different components? C 100

27. Sieve C 100

28. Why are sieves used to analyze soil? ____________ C 200

29. They separate soil by particle size. C 200

30. What are mixtures of different elements and chemical compounds that combine in different proportions to form hard, solid materials of the earth’s surface? C 300

31. Rocks C 300

32. DAILY DOUBLE C 400 DAILY DOUBLE Place A Wager

33. What are the elements and compounds found in rocks? They are solid and possess a crystal structure. C 400

34. Minerals C 400

35. What is the mixture of organic component, sand and gravel that makes up the upper surface of the Earth? C 500

36. Soil C 500

37. Why would marble gravel weather faster than quartz gravel? D 100

38. The quartz will not react as fast as the marble when exposed to certain chemicals. D 100

39. What are some things that a person could do to reduce erosion. Name two and explain. D 200

40. Vegetation could be added. Vegetation decreases erosion by slowing the flow of water and by catching and preventing soil from flowing down the hill. Obstacles could also be added. These also slow down the water and catch the soil. D 200

41. What are two processes that contribute to forming and depositing soil? D 300

42. Weathering and erosion. D 300

43. Fragments of rock provide nutrients for living plants. True/False D 400

44. True D 400

45. Would plants releasing oxygen into the air speed up chemical weathering? Yes/ No D 500

46. Yes D 500

47. Would a large stone statue or marble gravel weather faster? E 100

48. Marble gravel E 100

49. A scientific tool used to measure mass. E 200

50. A triple beam balance E 200

51. A tool used to measure volume. E 300

52. A graduated cylinder or a beaker or a falcon tube. E 300

64. What is Tasmania? F 400

65. Although the National Bird of New Zealand, it is also indigenous to Australia F 500

66. What is the Kiwi? F 500

68. How does physical and chemical weathering combine to weather rocks? Click on screen to continue

69. By breaking rocks into smaller pieces, physical weathering exposes more of a rock’s surface to chemical weathering. Chemical weathering softens and weakens rocks. The combination of the two speeds the overall process of weathering. Click on screen to continue
