results more reliable?
Answer
• Repeat the experiment
Thinking of the Music experiment…..
What is one thing that could have happened to
make the results less reliable?
Answer
• Many possible answers….changing or altering
any of the controlled variables causes results
to be unreliable

    33. 33. Answer • Biosphere
    34. 34. Volcanoes and Earthquakes are found in what sphere?
    35. 35. Answer • Geosphere
    36. 36. Explain how a volcanic eruption from the geosphere could effect 2 other spheres?
    37. 37. Answer • Atmosphere: ash and gases ejected from eruption • Hydrosphere: ash deposits contaminate water • Biosphere: Plants and animals are unable to survive due to air and water quality, habitat destruction • Geosphere: New rock is formed from cooled lava, ash gets into soil and adds nutrients
    38. 38. What is one feature of the atmosphere?
    39. 39. Answer • • • • • Mostly Nitrogen Causes weather Keeps temps stable Protects from radiation Protects from meteors
    40. 40. A closed system exchanges ________ but not __________ with its surroundings
    41. 41. Answer • Energy NOT matter
    42. 42. Give one reason as to why the hydrosphere is an open system
    43. 43. Answer • Water is transferred physically between the hydrosphere and atmosphere
    44. 44. How is the biosphere part of the nitrogen cycle?
    45. 45. Answer • Bacteria fix nitrogen into usable forms for plants, plants absorb it through their roots, then animals eat plants. When living things die, they decay and release nitrogen back into the soil. Another type of bacteria may transfer it back into the atmosphere
    46. 46. Where is one place that Carbon is stored on Earth?
    47. 47. Answer • Ocean • Rock • Living things
    48. 48. How have humans altered the natural balance of the Carbon cycle?
    49. 49. Answer • By burning fossil fuels at high rates and deforestation
    50. 50. How could using too much fertilizer (nitrogen) effect the environment? (be specific)
    51. 51. Answer • Plants use nitrogen to grow, but any unused nitrogen will run off into nearby rivers and lakes and accumulate. Plants in the lake may overgrow, causing an imbalance in the food chain.
    52. 52. How does removing rainforests affect the Carbon cycle?
    53. 53. Answer • The more trees are removed, the less plants there are to take in carbon from the atmosphere
