Using Figure 7 and your own knowledge, assess the role of mass movement upon the development of this area of the Holderness coastal landscape.
Figure 7
Holderness is overlaid with unconsolidated glacial deposits which lie on top of chalk. The landscape is dominated by deposits of till, boulder clays and glacial lake clays. The glacial deposits form a continuous lowland plain. Rainfall is below national average but the area is prone to heavy storms.

Using Figure 1 and your own knowledge, assess the effectiveness of hard engineering in managing coastal erosion.
Figure 1: Mean annual cliff retreat rate (metres per year) at three locations on the Holderness coast, 1980–2015
Location | 1980–1991 (before Mappleton groynes) | 1991–2015 (after Mappleton groynes) |
|---|---|---|
Mappleton (protected site) | 2.1 | 0.3 |
0.5 km south of Mappleton | 2.0 | 4.6 |
Withernsea (15 km south) | 2.2 | 2.1 |
