Coastal Landscape Development (AQA A Level Geography)

Figure 6 is a photograph of a landform located in the Humber Estuary, UK.

Figure 6

Note: This landform extends about 5 km across the Humber Estuary and is only 50 metres wide at its narrowest point. The Holderness coastline to the north comprises mainly boulder clay, which is unconsolidated material deposited at the end of the last ice age.

Using Figure 6 and your own knowledge, assess the relative importance of factors leading to the development of this landform.

Figure 5 shows the isostatic adjustment in 2010 (green arrows) for selected recording stations in Greenland. Information on the 2010 melting day anomaly is also shown.

Analyse the relationship between isostatic adjustment and the 2010 melting day anomaly in Greenland as shown in Figure 5.

Figure 6 is a photograph of a coastal feature, taken in Malta in 2017.

Using Figure 6 and your own knowledge, assess the view that rock type is the most important factor in the development of this landscape

[6]

With reference to a coastal environment at a local scale, assess the predicted impact of climate change upon the landscape.

[20]

Explain the development of saltmarsh environments.

Figure 6 is a photograph of a stretch of coastline in the Mahia Peninsula, North Island, New Zealand.

Figure 6

Note: In New Zealand, there is a variety of coastal dune landforms. The dunes in Figure 6 are relatively small shore-parallel foredunes located immediately behind the beach. Dunes can be made up of a variety of surface dune types. They can form hills and ridges which can rise to a hundred metres or more above the shoreline and represent long-term accumulations of large volumes of sand.

Using Figure 6 and your own knowledge, assess the role of vegetation in the development of this landscape.

Outline the processes which lead to the development of barrier beaches.

Figure 6a indicates sea levels relative to land 20 000 years before present. The present day coastline is indicated for comparative purposes.

Figure 6b indicates present day sea levels.

Using Figure 6a, Figure 6b and your own knowledge, assess the potential impact of box these changes on coastal landform development in this area.
