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.

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

Note: 1 Melting day anomaly refers to the extra days of melting relative to the 1979–2009 average.

2 Isostatic adjustment refers to the change in the land level relative to sea level.

b)

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

Figure 5 shows data related to the distribution of beach erosion and accretion measured from 1984 to 2016. Accretion occurs when more sand is accumulated on beaches than is lost to erosion.

Distribution of beach erosion and accretion from 1984 to 2016

The bar graph beneath the map presents the relative occurrence of eroding and accreting sandy shorelines per degree of longitude. The numbers presented on the map represent the average change rate for all sandy shorelines per continent.

Analyse the data shown in Figure 5.
