Although less powerful, the earthquake in Russia caused more deaths
than the Peru earthquake. Tick (9) two boxes below which are TRUE
statements.

More deaths were caused by the Russian earthquake because
the population were aware of the dangers
the buildings were closer together
there were more businesses nearby
there was a low population density.

Describe one way in which the number of deaths from an earthquake
can be reduced.

GCSE GEOLOGY SPECIMEN THEORY PAPER
MARK SCHEME
GENERAL MARKING GUIDANCE
Positive Marking
It should be remembered that candidates are writing under examination conditions and credit
should be given for what the candidate writes, rather than adopting the approach of
penalising him/her for any omissions.
Unexpected but acceptable answers
The mark scheme gives an indication of the likely responses of candidates but examiners
must be prepared to award marks appropriately for answers which are unexpected but are
nevertheless worthy of credit. If an examiner is unsure about the validity of such a response
they should seek advice from the chief examiner.
Quality of Written communication
This is assessed in questions 3(c) and 7(b) of this specification paper according to the levels
of response shown in the mark scheme.

between the two beds is marked with a pothole in the limestone partly infilled with the
overlying sandstone. (Figure 6).

Assessment Framework for Controlled Internal Assessment
AO1
Knowledge
and
understanding
of
geology and how the
science works
(i)
knowledge
techniques
of
geological
(ii) relate collected data to current
geological explanations and
theories
AO2
Application of skills,
knowledge
and
understanding
(i) plan an extension to the
investigation or plan a subsequent
investigation
0-2
Limited knowledge of geological
explanations and theories which
explain the collected data.
0-2
Plan using basic equipment and
simple procedures.
3-5
Thorough knowledge of a wide
range of geological techniques
such as measuring dip and strike,
rock description and identification,
sampling, fossil description and
identification,
construction
of
sedimentary logs, mapping.
3-5
Thorough knowledge of geological
explanations which explain the
collected data.
3-5
A detailed plan identifying suitable
equipment and procedures to
collect accurate observations.
0-1
Ideas are present but not linked.
Information is not organised
clearly. Specialist vocabulary is
limited and there are errors in
SPG which may impede
communication.
2-3
Ideas are linked and information
organised to convey meaning
clearly. Some specialist
vocabulary is used. There are
some errors in SPG.
4-5
The account presents a logical
flow of argument, with clear links
between ideas. Specialist
vocabulary is used with
confidence. SPG is largely error
free.
(ii) record observations
0-3
Use a piece of equipment safely to
collect some observations or
measurements and record them as
simple field notes.
4-7
Collect observations or
measurements which are
appropriate for the enquiry using
several pieces of equipment.
Record the observations clearly as
field notes.
8-11
Collect accurate observations
which are adequate to complete
the enquiry using a suitable range
of equipment. Record the
observations clearly and accurately
as field notes, using an appropriate
format.
(iii) analysis; process and interpret
data
0-2
Simple statement about what the
observations show.
3-5
Show the observations as simple
diagrams/photographs or a graph.
Identify a trend or simple
interpretation of the observations.
3-5
Assess the accuracy of the
equipment used and secondary
data. Comment on the suitability of
the methods used for making
observations.
6-8
Process the observations in a
range of formats suitable for
adequate interpretation. Interpret
the observations.
(ii) develop a geological argument
within the context of the enquiry
AO3
