Scheme of assessment





Number of assessment units = 6
One of the assessment units at AS and one of the
assessment units at A2 must be internally assessed.
Each of the internally assessed units at AS and A2
must include the assessment of practical skills 20 –
30% of AS and A2.
There is a requirement for synoptic assessment at A2
AS and A2 level specifications must assess the
candidates’ quality of written communication
Geology – knowledge and
understanding
The AS ~60% knowledge and understanding
 The AS and A2 combined ~60 % knowledge and
understanding.
All specifications must require students to develop:
 a broad understanding of geological processes operating
at a range of scales in space and time
 geological investigation skills and knowledge, and an
understanding of how these are applied in practical
and/or field geology
 a scientific understanding of the Earth, its evolution and
its sustainable development.

GL4: INTERPRETING THE
GEOLOGICAL RECORD






Written Paper - 2 hours (17.5% of A Level )
Integrated short answer paper interpreting a variety of
data including geological maps.
Rock forming processes.
Rock deformation.
Past Life and Past Climates
(Renamed E3 formerly The Fossil Record ).
Geological map interpretation.*
GL4: INTERPRETING THE
GEOLOGICAL RECORD
Changes
 Minor clarification changes to original content
 New Key Idea 2 – “Fossils provide evidence of
increasing diversity of life through geological time”.
Knowledge has been clarified to highlight stages in the
development of life and mass extinctions.
e.g. Ediacaran fauna, Cambrian explosion, migration to
life on land, causes of extinction events.
GL4: INTERPRETING THE
GEOLOGICAL RECORD





New Key Idea 3 “ A combination of global
factors contributes to climate change through
geological time.”
Continent and montain belt distribution
Milankovitch cycles
Greenhouse gas changes and natural processes
Rates of past and present climate change.
Key Idea 3: A combination of global
factors contributes to climate change
through geological time




(a) The distribution of continents and mountain belts
controls oceanic and atmospheric circulation and
influences global climate;
(b) Milankovitch cycles as a contributory cause of ice
ages.
(c) Atmospheric composition: the concentration of
CO2 and methane, and natural and man-made
contributions ….;
(d) Rates of past and present changes.
GL4: INTERPRETING THE
GEOLOGICAL RECORD
New Key Idea 4 – “ Evidence of climate
change is obtained from the fossil record,
sedimentary rocks and ocean sediments”
Includes :
faunal evidence from land plants and corals
a comparison of Carboniferous (icehouse) and
Cretaceous (greenhouse).
18O/16O isotopes
“Snowball Earth”

Key Idea 4: Evidence of global climate
change is obtained from the fossil record,
sedimentary rocks and ocean sediments.



(a) Fossil record provides evidence for different
climatic zones: land plants and corals
(b) Sedimentary rocks provide evidence of
depositional environments related to particular
climatic zones (eg, icehouse v greenhouse);
(c) Oxygen isotope ratios (18O/16O) in fossil shells are
indicative of the temperature of ancient ocean waters
GL4: INTERPRETING THE
GEOLOGICAL RECORD
Geological map interpretation.
