1 Which of these is an example of a
sedimentary rock?
A soil
B limestone
C gravel
D tarmac
1 Which of the following is an igneous rock?
A granite, which is a hard rock with
interlocking crystals
B chalk, which is made from the remains of
sea organisms
C slate, which has interlocking crystals
arranged in layers
D sandstone, which is formed from rounded
grains of sand
2 The grains of rock that form sedimentary
rocks were formed by weathering and
erosion. Which statement is correct?
A Weathering breaks up the rocks, and
erosion moves the bits away.
B Erosion breaks up the rocks, and
weathering moves the bits away.
C Erosion is caused by chemical reactions.
D Weathering happens fastest in dry weather.
3 Sedimentary rock is formed when grains of
rock get fixed together by:
A compaction and cementation.
B squeezing the dry rock grains together.
C adding clay particles.
D adding water to the mixture.
4 A sedimentary rock is made of very small
grains. What does the grain size tell us about
the rock?
A It will be dark coloured.
B The grains were deposited by fast-moving
water.
C The grains were deposited by slow-moving
water.
D The rock contains fossils.
2 Igneous rocks are formed when:
A magma or lava is put under pressure.
B magma or lava cools down.
C magma or lava is heated up.
D magma or lava evaporates.
3 When an igneous rock is forming:
A large crystals will form if the magma heats
up quickly.
B small crystals will form if the magma cools
slowly.
C large crystals will form if the magma cools
slowly.
D small crystals will form if the magma
evaporates quickly.
4 According to the particle theory, large crystals
will form if:
A the particles have time to collect together
before they cool.
B the particles are kept as far apart as
possible.
C the particles have time to collect together
before they melt.
D the particles cool quickly and don’t have
time to move apart.

1 Which rock is a metamorphic rock?
A basalt, which is formed when lava cools
down
B granite, which has interlocking crystals of
different sizes
C gneiss, which has interlocking crystals in
coloured bands
D mudstone, which is formed from mud
particles stuck together
1 What is a scientific theory?
A a description of what a scientist found out
in an experiment
B an idea that can explain observations and
be used to make testable predictions
C a prediction of what will happen in an
experiment
D a story about how the Earth formed
2 Which of these statements is not true?
A The Bible describes how some Christians
think the Earth was formed.
B Most rocks on the Earth are older than
6000 years.
C Predictions made using creationism have
been tested and are wrong.
D Almost all scientists think that creationism
is a good scientific theory.
2 Metamorphic rocks are formed by the effects
of:
A the high pressure and low temperature
inside the Earth.
B the high pressure and high temperature
inside the Earth.
C the low pressure and high temperature
inside the Earth.
D the low pressure and low temperature
inside the Earth.
3 Which of the following statements is true?
A Marble is formed from limestone.
B Marble is not a metamorphic rock.
C Slate is formed from granite.
D Gneiss is formed from marble.
4 Which statement describes some of the ways
in which metamorphic rocks are different
from sedimentary rocks?
A Metamorphic rocks do not contain crystals
and are very porous.
B Metamorphic rocks are softer, more porous
and have large grains.
C Metamorphic rocks may be harder, less
porous and have crystals that may be lined
up.
D Metamorphic rocks are softer, less porous
and may contain clear fossils.

3 Which statement is true?
A The catastrophe theory says that all rocks
were formed very slowly.
B Most scientists agree that the catastrophe
theory is a good scientific theory.
C Volcanic eruptions are evidence in favour of
the catastrophe theory.
D There is no evidence in favour of the
catastrophe theory.
4 Which statement is true?
A The theory of uniformitarianism says that
all rocks were formed by sudden events.
B Scientists think the theory of
uniformitarianism is correct.
C Scientists think the theory of
uniformitarianism is mostly correct.
D The Earth is too young for
uniformitarianism to be correct.
