Fragen in diesem Quiz (8)

  1. 1Which of the following is a sustainable resource?
    1. AManaged forest
    2. BOil
    3. CGold
    4. DCoal
  2. 2Complete the following sentences about treating fresh water.

    In the United Kingdom (UK), rain provides water with low levels of dissolved substances (called [blank_start]fresh[blank_end] water) that collects in the ground and in lakes and rivers.
    To make this water potable, it must go through these steps:
    [blank_start]sedimentation[blank_end] - solids sink to the bottom and are removed
    [blank_start]filtration[blank_end] - fine particles like sand are removed
    sterilising - microbes are [blank_start]killed[blank_end]
    1. Afresh
    2. Bsedimentation
    3. Cfiltration
    4. Dkilled
  3. 3Two new mobile phones have been designed, the one with the most positive LCA has been selected to be manufactured. Select from below a quality that would have contributed towards its selection:
    1. Aimported long distances
    2. Bmade from plastic
    3. Climited battery life
    4. Dcarbon neutral manufactoring
  4. 4Which of the following are the ways in which fresh water is sterilised?
    1. Aozone
    2. Bchlorine
    3. Cultraviolet radiation
    4. Dinfrared radiation
    5. Ehydrogenation
  5. 5You need to know about these two methods, and be able to compare them to each other and traditional mining. Complete the sentences below.

    Phytomining uses [blank_start]plants[blank_end] to absorb metal compounds. The plants are harvested and then [blank_start]burned[blank_end] to produce ash that contains metal compounds.
    [blank_start]Bioleaching[blank_end] uses bacteria to produce [blank_start]leachate[blank_end] solutions that contain metal compounds.
    1. Aplants
    2. Bburned
    3. CBioleaching
    4. Dleachate
  6. 6The reduction in use, reuse, and recycling of materials reduces the use of: 
    1. Aenvironmental impacts
    2. Bwaste
    3. Cenergy sources
    4. Dlimited resources
    5. Ecargo donkeys
    6. Ftransportation
    7. Gmusical chairs
  7. 7Put the following statements in the correct order to describe how waste water is treated:
    A - sedimentation to produce sewage sludge and effluent
    B - screening and grit removal
    C - aerobic biological treatment of effluent
    D - anaerobic digestion of sewage sludge
    1. AB, A, D, C
    2. BA, B, D, C
    3. CB, D, C, A
    4. DA, D, C, B
  8. 8If supplies of [blank_start]fresh water[blank_end] are limited (such as on an small island), [blank_start]desalination[blank_end] of [blank_start]sea water[blank_end] (high salt levels) may be required. Desalination can be done by [blank_start]distillation[blank_end] or by processes that use membranes such as [blank_start]reverse osmosis[blank_end]. These processes require [blank_start]large[blank_end] amounts of energy.
    1. Adesalination
    2. Bsea water
    3. Cfresh water
    4. Ddistillation
    5. Ereverse osmosis
    6. Fchromatography
    7. Gcrystallisation
    8. Hlarge
    9. Ismall
