Worksheet time: 7mins
rounded grains of three different minerals
interlocking grains of two different minerals
interlocking crystals of three different minerals
rounded grains with gaps between them
Some rocks are permeable because:
the rock dissolves in water.
water can get into gaps between the grains.
animals have dug burrows in the rock.
the rock is made of interlocking crystals.
Igneous rocks are formed when:
magma or lava is put under pressure.
magma or lava cools down.
magma or lava is heated up.
magma or lava evaporates.
When an igneous rock is forming:
large crystals will form if the magma heats up quickly
small crystals will form if the magma cools slowly.
large crystals will form if the magma cools slowly.
small crystals will form if the magma evaporates quickly.
According to the particle theory, large crystals will form if:
lots of particles have time to bond together into a regular pattern before the liquid cools.
the particles are kept as far apart as possible.
the particles have time to collect together before they melt.
the particles cool quickly and don’t have time to move apart.
Metamorphic rocks are formed by the effects of:
high pressures or low temperatures.
high pressures or high temperatures.
low pressures or high temperatures.
low pressures or low temperatures.
Physical weathering happens to rocks when:
the weather is always hot.
the weather keeps changing between hot and cold.
the weather is always cold.
the rock gets struck by lightning.
Freeze–thaw action damages rocks because:
the rocks melt.
the rocks freeze.
water expands when it thaws.
water expands when it freezes.
Which of these statements is true?
Chemical weathering always involves water.
Physical weathering always involves water.
Chemical weathering depends on temperature changes.
Biological weathering happens because rain water is slightly acidic.
Which statement is true?
Ice can transport only small rocks.
Wind can transport larger particles than water.
The slower water is moving, the larger the particles it can carry.
Water can transport larger particles than wind.
Which is the best statement to complete this sentence?
Sedimentary rocks are formed when:
sediments are compacted and then cemented.
sediments are cemented and then compacted.
sediments are buried and compacted.
rocks are weathered and eroded.
Fossils are usually:
skeletons of animals.
different layers of sediment.
very old animals.
the shapes of dead animals or plants that were buried in sediments.
Which statement describes some of the ways in which metamorphic rocks are different from sedimentary rocks?
Metamorphic rocks do not contain crystals and are very porous.
Metamorphic rocks are softer, more porous and have large grains.
Metamorphic rocks may be harder, less porous and have crystals that may be lined up.
Metamorphic rocks are softer, less porous and may contain clear fossils.
