The 20 questions
-
A local glacial case study should aim to:
- Describe local food with no link to processes, which is a matter of culture rather than geography
- Provide only a photograph collection of the glacier, with a short caption for each image
- Illustrate fundamental glacial processes and their landform outcomes using field data
- List the names of all mountain peaks in the region, with their heights and locations
-
Which evidence from a local glacial case study best shows the operation of glacial deposition?
- A count of the number of mountain huts in the region, which shows the infrastructure present
- A record of the average temperature in the nearest city, which shows the climate of the town
- Mapping of moraines and till deposits with their composition and sorting
- A list of the tourists who visited the glacier, which shows the number of people in the area
-
Which element is important in a contrasting glacial case study from beyond the UK?
- A description of the weather with no link to landforms, which describes the climate alone
- A list of hotels near the glacier, which shows the accommodation available to visitors
- A list of the glacier's length without interpretation, which records only the measurement
- An evaluation of how the glaciated landscape presents challenges and opportunities for human occupation
-
Which approach best evaluates human responses in a glaciated environment?
- Ignoring responses that have had negative side effects, which keeps the evaluation focused on success
- Judging responses only by their cost, which is the simplest measure to obtain from the accounts
- Assuming all responses are equally effective without evidence, which avoids the need for measurement
- Assessing whether responses build resilience, mitigate hazards or adapt to change, with evidence of effectiveness
-
A glacial case study shows that a valley has been reshaped by plucking and abrasion. Which evidence would best support this?
- Stacks and arches in a sea cliff, which are formed by the waves of the coast
- Cuspate spits and barrier beaches on the valley floor, which are built by longshore drift
- Barchan dunes and yardangs in a desert, which are formed by wind action on sand
- Roches moutonnees and striated bedrock surfaces with plucked lee faces
-
Which statement about the use of field data in a glacial case study is most appropriate?
- Field data should be collected without a purpose and then ignored, which allows an open-minded account
- Field data should be linked to the processes being studied and used to test a specific question
- Field data should replace all analysis of the processes, so that the report presents only numbers
- Field data should be used only to decorate the report, which makes the findings look more attractive
-
Which change over time would be the strongest evidence of glacial retreat in a local case study?
- A series of dated maps showing the terminus retreating and ice-free ground expanding
- A single photograph showing ice cover at one date, which records the position only once
- A map of the valley without dates, which shows the layout of the landscape but not its change
- A local rumour that the glacier was larger in the past, which has not been recorded or checked
-
In a glacial case study of human impacts, which combination best describes a sustainable approach?
- Unregulated tourism with no monitoring of the glacier, which lets visitors go wherever they choose
- Construction of new roads across all sensitive ground, which improves access for visitors and workers
- Regulated tourism, protected zones and monitoring of the glacier and its landforms
- Removal of the glacier's moraines for construction materials, which provides cheap building stone
-
Which factor is most important when comparing a local glacial case study with a case study from beyond the UK?
- Whether both studies used the same colour of map, which affects only the presentation
- Whether the glacial processes and landforms are comparable, and how the human context differs
- Whether the two glaciers share the same name, which is a matter of chance and not of process
- Whether both studies were carried out in the same year, which has no effect on the processes
-
Which conclusion would be most supported by a local glacial case study that measured sediment and landforms?
- Glacial processes have produced characteristic landforms, and the local landscape reflects past and present ice activity
- Glaciers are irrelevant to the shape of the valley, which is formed by rivers alone
- Sediment has no link to the glacier's movement, because it is carried only by the wind
- Landforms have no link to any process, since they form at random across the landscape
-
Which weakness should be acknowledged in an evaluation of a glacial case study?
- Glacial processes are unrelated to climate, so the timespan of the data does not matter
- The short timespan of data may not capture long-term variability in glacier behaviour
- Glaciers never change over any timespan, so a short record is always fully representative
- Field measurements are always entirely free of error, so limitations need not be discussed
-
Which description of a balanced glacial case study conclusion is most appropriate?
- The response is an absolute success with no challenges, which means no further action is needed
- The response has improved some outcomes but challenges remain, and its long-term success depends on continued monitoring
- The response should be ignored because glaciers cannot be managed in any practical way
- The response has no effect on the glacier or its people, which means it can be discontinued
-
Which feature of a glaciated landscape is most useful for interpreting past ice extent?
- Lateral and terminal moraines that mark former margins of the ice
- Coastal spits built by longshore drift, which show the direction of the waves on the shore
- Stacks formed by the collapse of arches, which show the erosion of sea cliffs over time
- Modern dunes built by the wind, which show the direction of the prevailing winds in the desert
-
A case study concludes that a glacial lake formed behind a moraine. Which evidence would best support this?
- A list of the lake's fish species with no geological data, which describes the biology of the water
- A photograph of the lake taken in a single summer day, which shows its appearance at one time
- Mapped moraine dam, lake sediments and shoreline features that match a damming history
- A tourist guide's description of the lake's beauty, which describes its scenery for visitors
-
Which evidence would best show that a glacier is currently in retreat?
- A map of the glacier with no dates or scale, which shows its outline only
- A series of dated photographs or maps showing the terminus moving upvalley
- A local belief that the glacier looks smaller than in the past, with no record
- A single photograph taken during a heavy snowfall in winter, which hides the terminus
-
What is the most suitable way to present glacier retreat data in a case study?
- A pie chart showing the share of each rock type in the valley, which does not show change
- A bar chart of rainfall totals in unrelated years, which does not relate to the glacier
- A table of tourist numbers only, which does not show the position of the ice
- A line graph of terminus position against date, with the rate of retreat shown
-
A case study proposes monitoring a glacier with repeat surveys. What is the main benefit of this?
- It removes the need to take any further field measurements in future years of the study
- It ensures that the glacier will stop retreating once the monitoring programme begins
- It allows the glacier to be classified as cold-based without any other data being collected
- It provides evidence of change over time that can separate trend from variation
-
Which human response to glacier retreat is most closely linked to adaptation?
- Constructing a dam to freeze the meltwater before it reaches the valley below
- Painting the glacier surface white to increase its albedo and slow the melt
- Adjusting water supply and hazard warning systems for downstream communities as meltwater changes
- Removing debris from the glacier snout to prevent the ice from melting faster
-
Which is the best evaluation of a glacial hazard management scheme?
- Whether it has reduced risk to people and property and whether it remains sustainable over time
- Whether it uses the highest-cost materials available on the market at the time
- Whether its design was approved by the most senior officials in the government
- Whether the scheme attracts the most attention in the local media during its launch
-
Why might a case study of a glacial valley be compared with a case study from another glaciated region?
- To show that glacial landforms are unrelated to any process operating on the ice
- To test whether similar landforms arise from similar processes under different conditions
- To establish which glacier has the longest name in the comparison of the two regions
- To prove that all glaciers in the world are identical in their behaviour and their landforms
