Section A Landscape
Systems
Choose one option and answer all the parts of the question in your chosen option.
Option A – Coastal Landscapes
1
(a) Explain the influence of flows of energy in the formation of a salt marsh. [8]
(b) Study Table 1, which shows cliff erosion rates on the East Yorkshire coast, UK.

Bridlington 1.00
Barmston 2.00
Hornsea 0.25
Mappleton 1.50
Aldbrough 0.80
Grimston 1.10
Tunstall 0.75
Withernsea 2.20
Out Newton 1.90
Spurn neck 3.10
(i) Using Table 1, calculate the mean rate of erosion.
Show your workings. [2]
(ii) The standard deviation for the rate of erosion in Table 1 is 0.8.
State what this indicates about the dispersion (spread) of the data set. [2]
(iii) Explain why standard deviation is a more accurate measure of dispersion (spread) than range
and interquartile range. [2]
(c) Study Fig. 1, a coastal landscape in Norway.
With reference to Fig. 1, explain the influence of one geomorphic process in shaping landform A
(fjord). [3]
(d) * ‘Coastal landscape systems are influenced more by management strategies than by the
unintentional impacts of economic development.’
To what extent do you agree with this statement? [16]

Option B – Glaciated Landscapes 2
(a) Explain the influence of flows of energy in the formation of a drumlin. [8]
(b) Study Table 2, which shows valley erosion rates along a glacier in India.

(i) Using Table 2, calculate the mean rate of erosion.
Show your workings. [2]
(ii) The standard deviation for the rate of erosion in Table 2 is 21.7.
State what this indicates about the dispersion (spread) of the data set. [2]
(iii) Explain why standard deviation is a more accurate measure of dispersion (spread) than range
and interquartile range. [2]
(c) Study Fig. 2, a periglacial landscape in Iceland.
With reference to Fig. 2, explain the influence of one geomorphic process in forming landform B
(patterned ground). [3]
(d) * ‘Periglacial landscape systems are influenced more by human activity than glacial landscape
systems.’

3
(a) Explain the influence of flows of energy in the formation of a linear dune. [8]
(b) Study Table 3, which shows canyon erosion rates in a dryland landscape in China.

(i) Using Table 3, calculate the mean rate of erosion.
Show your workings. [2]
(ii) The standard deviation for the rate of erosion in Table 3 is 1.11.
State what this indicates about the dispersion (spread) of the data set. [2]
(iii) Explain why standard deviation is a more accurate measure of dispersion (spread) than range
and interquartile range. [2]
(c) Study Fig. 3, a dryland landscape in Chad.
With reference to Fig. 3, explain the influence of one geomorphic process in shaping landform C
(nivation hollow). [3]
(d) * ‘Dryland landscape systems are influenced more by human activity, due to water supply issues, than by
economic activity.’
