36. Explain how a volcanic eruption from the
geosphere could effect 2 other spheres?
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
43. Answer
• Water is transferred physically between the
hydrosphere and atmosphere
44. How is the biosphere part of the nitrogen cycle?
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. Where is one place that Carbon is stored on
Earth?
50. How could using too much fertilizer (nitrogen)
effect the environment? (be specific)
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.
