Edexcel A Level Geography Paper 1 June 2023 question paper 9GE0/01

Study Figure 1 below.

The data was collected to investigate whether there was a significant relationship between the population living within 5km of a volcanic location and the years since the last eruption, at 10 selected locations.

The population living within 5km of a volcanic location and the years since the last eruption, at 10 selected locations.

Calculate Σd².

The formula for Spearman’s rank correlation coefficient value r_s is given below.

In this data set n = 10.

Calculate the value of r_s, to two decimal places, for the data given.

You must show your working.

The tables below show the two hypotheses that are being tested and the critical values of Spearman’s rank r_s when n = 10.

Using the Spearman’s rank correlation r_s value calculated in (a)(ii), state which hypothesis can be accepted.

Assess the effectiveness of strategies used to manage the impacts of volcanic hazards.

Study Figure 2a in the Resource Booklet.

Explain the contribution of meltwater to the movement of temperate glaciers.

Study Figure 2b in the Resource Booklet.

Explain the role of feedback in changing the size of ice sheets and sea ice.

Explain the role of melting and refreezing cycles in forming distinctive periglacial landforms.

Evaluate the view that the management of active and relict glaciated landscapes is likely to be unsuccessful.

Do not answer Question 3 if you have answered Question 2.

Coastal Landscapes and Change

You must use the Resource Booklet provided.

Study Figure 3a in the Resource Booklet.

Explain the contribution of erosional processes in producing sediment.

Study Figure 3b in the Resource Booklet.

Explain the role of global warming in changing mean sea level since 1920.

Explain the role of geology in the formation of contrasting cliff profiles.

Evaluate the view that without hard engineering there is little future for coastal communities threatened by coastal recession and flooding.

Study Figure 4a in the Resource Booklet.

Explain one possible impact on local communities of the development of onshore wind farms.

Explain how adaptation strategies, such as water conservation, may help communities cope with a changed climate.

Explain how water insecurity can cause both social and economic problems.

Study Figure 4b and 4c in the Resource Booklet, which show two neighbouring upland river catchments and their hydrographs following a local storm event.

Assess the extent to which land use affects the shape of these storm hydrographs.

The processes of the carbon cycle operate at longer and slower (geological) and shorter and faster (biological) timescales.

Evaluate the view that human activities are having a greater impact on shorter term biological processes than on longer term geological processes.
