(b)
Achievement with Merit
Describes ONE of:
High temperature / heat +
pressure
OR
Uplift / Folding leading to
exposure
OR
Sediments forming layers
OR
Undergoes subduction / Deep
underground & plate tectonic /
Plate tectonic & large
geographic area
Explains TWO of:
1. Place
 Plutonic/ Intrusive/
underground
2. Cooling rate
 Slow cooling
3. Crystal size
 Large crystals
4. Silica
 High silica content & lighter
colour
Discusses all FOUR factors to the
formation of granite.
1. Place
 Plutonic/ Intrusive/ underground
2. Cooling rate
 Slow cooling
3. Crystal size
 Large crystals
4. Silica
 High silica content of magma
lighter colour
Explains TWO processes that led
to the appearance of schist:
Layers
 Sediment is deposited in layers
(on the sea floor).
Metamorphic Process
 Heat/ high temp + pressure &
recrystallisation / Alters
chemical composition
Regional Process
 Plate tectonic movement &
deep underground
OR
 Plate tectonic movement &
large geographic areas
/ Subduction
Appearance
 Uplift or folding and exposed /
Plate tectonic movements
linked to exposure
Discusses THREE processes that led
to the appearance of schist:
Layers
 Sediment is deposited in layers
(on the sea floor).
Metamorphic Process
 Heat/ high temp + pressure plus
recrystallisation / Alters chemical
composition
Regional Process
 Plate tectonic movement & deep
underground
OR
 Plate tectonic movement & large
geographic areas / Subduction
Appearance
 Uplift or folding and exposed /
Plate tectonic movements linked
to exposure

THREE
(a)
(b)
Describes one aspect of moving
particles.
Size of particles are explained
along with transport & erosion.
Compare size of particles with
transport & erosion.
 Big boulders are hard / too
heavy to move / transport.
OR
 Sand / gravel easy to move.
OR
 Boulders break down into
gravel (erosion).
OR
 Sand / gravel have moved a
distance (Boulders not
moved).
OR
 Insufficient energy / current to
move boulders.
OR
 Mountain streams have
enough energy to transport
small & gravel.
Large boulders have had short
time / not enough distance from
the source / insufficient energy to
be broken down into a small sized
rock particle.
OR
Sand and gravel have travelled for
a long time / far enough distance
from the source / sufficient
energy to be broken down into a
small sized rock particles.
Large boulders have had shorter time
/ not enough distance from the source
/ insufficient energy to be broken
down into smaller sized rock
particles.
OR
Sand and gravel have travelled for a
longer time / far enough distance
from the source / sufficient energy to
be broken down into smaller sized
rock particles.
Describe one geological event/
process or environment relating
to a rock formation.
Explain one geological event/
process and environment relating
to a rock formation.
Relate or Justify two consecutive
geological events/ processes and
environments in relation to the rock
formations.
Refer to table below.

Limestone submerged again
Sea level rising
 Sandstone from a high energy
environment
 Siltstone & mudstone from a
low energy environment
 Hot spot
 Subduction
 Tectonic movements
Justification
Examples:
C is formed by a subduction zone
forcing magma up through all layers
making C the youngest rock.
Folding occurs after layers B and D
have been deposited as the rocks
above are horizontal.
Limestone above water due to uplift.
Erosion of limestone forms the
unconformity between the sandstone.
Relate
Change in sequence from event /
process and environment to the next
sequences event / process and
environment (use the table to help).
Eg
Relating the formation of B
(mudstone) sediment deposition
caused by low energy, followed by
uplift, forming shallow warm seas,
which led to the deposition of marine
animals.

(c)
Describe that:
Rocks with the same fossil
species in them are the same age.
OR
Describes the fossil to an
environment.
OR
Fossils present in a specific time
range (Appearance or
disappearance of a fossil).
Fossils that have a specific time
range before extinction are used
to establish age ranges of the
fossil therefore the rocks they are
found in can be relatively dated
(explanation).
AND
Identifies the environment as the
same (therefore same rock type).
