Exam-style Questions: The Earth and the Atmosphere

 

  1. An experiment was set up as shown below:

    Exam-style Questions

    The syringe on the left started with 100cm3 of air, the syringe on the right was empty.

    The air is passed from syringe to syringe through the glass tube and over the hot copper.

    This continues until there is no further change in the volume.

    a) What would be made as the air passes over the hot copper?

    (1 mark)

    b) What volume of air would be left in the syringe at the end of the experiment?

    (2 marks)

    c) Carbon dioxide is one of the gases found in the air.

    How can you test to see if a gas is carbon dioxide?

    Answer outline and marking scheme for question: 1

    a) Copper oxide.

    (1 mark)

    b) The air is about 20% oxygen.

    (1 mark)

    So 80% would be left = 80cm3 of air.

    (1 mark)

    c) Bubble the gas through (add to) limewater.

    (1 mark)

    Will turn cloudy if the gas is carbon dioxide.

    Answer

     

    Answer outline and marking scheme for question: 3

    a) A = igneous

    (1 mark)

    B = metamorphic

    (1 mark)

    b) Melting.

    (1 mark)

    c) Two from:

    Chalk/mudstone/limestone/sandstone/conglomerate.

    (1 mark each, maximum = 2 marks)

    (Total = 5 marks)

  4. Sedimentary rocks are formed when small particles are squashed together by other layers of sediment/rock being placed on them.

    Sedimentary rocks sometimes contain fossils that can be useful when dating the rock

    a) How can fossils be used to date sedimentary rock?

    (2 marks)

    b) From which type of sedimentary rock is marble formed?

    (1 mark)

    c) On the south coast of England, it is possible to see the 'White Cliffs of Dover'.

    How could you tell that the cliffs were made out of sedimentary rock?

    (1 mark)

    Answer

     

    Answer outline and marking scheme for question: 4

    a) Look at type of animal/plant that made fossil - find when animal/plant was alive.

    (1 mark)

    Type of animal/plant would have been alive when sedimentary rock was made so age of plant/animal is the same as the rock.

    (1 mark)

    b) Limestone.

    (1 mark)

    c) One from:

    • Rock is soft and made out of particles, which can be rubbed away with a fingernail.
    • It is possible to see layers in the cliff due to the different layers of sediment.
