Map 1 – Rock unit G is on top of Basalt (1) Rock G - is metamorphic therefore in the baked margin (1) Lava flow would not have an upper baked margin/sills have baked margins above and below (1)

What is the misinterpretation of the question here ?
SLIDE 16
This below scored all 3 marks for recognition that carbon capture is the essence of the question, that carbon dioxide is stored in depleted reservoirs, and that this will decrease the rate of global warming. Is there anything wrong with this answer that gained full marks?
SLIDE 17
The Applied Question in C2
There was an applied geology question related to map and
- ther evidence gathered in component 2
The pale grey rock (D) at Locality 5 has previously been interpreted as Limestone
What do you think the most obvious aspects are?
SLIDE 18
Any four x (1) from: Advantages
- Limestone strong rock so
stable dam foundations
- Horizontal beds to the East -
so stable
- High run off from the east to
fill reservoir Disadvantages
- Leakage from faulting/jointing
- Leakage from permeable
limestone
- Limestone collapse/sink holes
- Fault movement possible so
instability
- Beds dipping away therefore
leakage along the bedding plane

Is the answer of 38.2 worth any marks?
SLIDE 48
It was pleasing to see quite a number of correct answers though.
SLIDE 49
What is the error in this answer?
SLIDE 50
This is what we hoped to see, but the correct answer was seen less often than expected.
SLIDE 51
SLIDE 52
There were many answers like this. Not all the Maths questions are hard and this needs to be conveyed to candidates.
SLIDE 53
However there were still a variety of answers seen.
SLIDE 54
What do you think were the most common errors in answers to this?

Mineral Identification
Some mineral identification questions simply require candidates to look up the one correct answer from the Data Sheet.
SLIDE 65
Mineral Identification
Other mineral identification questions require more sophistication having looked up possible correct answers How many minerals have no cleavage and H = 5.5 or more ?
SLIDE 66
Mineral Identification
The main issue candidates had was the need for more than
- ne hardness test to
conclude that H is between 2.5 and 3.5.
SLIDE 67
Candidates were able to identify that Mineral Q is calcite. However this is not the answer to the next question.

Drawing Cross-sections
Guidance for teaching Geological Map interpretation and other aspects of the specification has been available as a recorded webinar available on the Eduqas website since Autumn 2018. This can be found towards the bottom of the GCSE Geology webpage
SLIDE 79
Drawing Cross-sections
At AS candidates are expected to draw quite complex cross-sections
- nto an entirely blank profile.
At GCSE candidates will only need to complete small sections of partially completed profiles.
SLIDE 80
Drawing Cross-sections
In GCSE mapwork candidates will need to be able to deal with Igneous bodies; plutons, dykes, sills, lava flows Horizontal beds Dipping beds Folded beds and fold axes Faults: normal, reverse, thrust, strike slip Unconformities
SLIDE 81
SLIDE 82
A common error was to draw vertical beds instead of horizontal
SLIDE 83
Or to draw them continuing the ‘SE’ trend from the map
SLIDE 84
There were quite a few correct interpretations however.
