  • Q1
    What is the rock cycle?
    How rocks evolve from volcanic magma, to igneous, break down into sediments to form sedimentary, then form metamorphic and heat and pressure, and finally melt back into melted rock as magma.
    Refers to Mohs Scale which looks at the properties of rocks
    The way in which a rock can turn over
    The birth, lifespan and eventual death of rocks

  • Q2
    What scale is used to show the hardness of rock
    1-10 scale
    Lustre
    Rock and hammer test
    Mohs scale
    30s
  • Q3
    What is the correct order on the Mohs scale from softest to hardest?
    Talc, quartz, feldspar, diamond
    Talc, feldspar, diamond, quartz
    Talc, feldspar, quartz, diamond
    Diamond, feldspar, quartz, talc
    30s
  • Q4
    Talc has a Mohs scale of 1
    False
    True
    30s
  • Q5
    Diamond has a Mohs scale of 100
    True
    False
    30s
  • Q6
    What type of rock is formed from cooled lava?
    Igneous rock
    Diamond rock
    Sedimentary rock
    Metamorphic rock
    30s
  • Q7
    How are large crystals formed in rocks?
    Are only formed in metamorphic rock
    By slow cooling over a long period of time
    By rapid cooling
    Bigger crystals are formed the deeper they are underground
    30s
  • Q8
    The natural breaking down of rocks into sediments is called what?
    Weathering or erosion
    Decaying and crumbling
    Weathering or escevation
    Melting by volcano
    30s
  • Q9
    What types of rocks are formed from ‘cementing’ of sediments?
    Talc
    Sedimentary rocks
    Metamorphic
    Igneous
    30s
  • Q10
    What type of rock is formed under heat and pressure?
    Sedimentary
    Granite
    Igneous
    Metamorphic rock
    30s
  • Q11
    Where are sediments most likely to end up?
    In volcanos
    In mountains
    In oceans and rivers
    In rocky road
    30s
  • Q12
    What does the lustre of rocksrefer to?
    The way a rock gives off light or shines
    How heavy it is
    The colour of the rock
    The colour it leaves when scratched against another surface
    30s
  • Q13
    What does ‘streak’ refer to when testing rocks?
    The amounts of streaks that are found in the rock
    The colour streaks found in the rock
    The size of the rock
    The colour of the powder that’s left behind when scratched against another surface
    30s
  • Q14
    How do we calculate the density of rock?
    Weight (g) ➗ Displacemebt (L)
    Weight (kg) ➗ Displacement (mL) =
    Weighing the rock
    Weight (g)➗ Displacement (mL) =
    30s
  • Q15
    Where is intrusive rock formed?
    In oceans
    On the earths surface
    In the air during a volcanic eruption
    In the earth
