The Erosion Threat Aims: To understand the physical and human factors that cause the Holderness Coast. To know there are variations in erosion rates. To know why the construction of dams cause erosion.

The geology is key to understanding why locations such Flamborough Head stick out as a ‘headland’ = resistant rock type along the coastline there is less resistant rock which is easily removed by the waves and transported as longshore drift

State the physical factors that are causing some coasts to recede faster than others.  

How do human actions interfere with the sediment cell and give a named example as part of your answer Bottom of p134 and top of 135

Under the variations in erosion rate – p135 Using a named example, explain why erosion rates vary in time and space on a stretch of coastline Under the variations in erosion rate – p135 Many factors to add here from the Holderness coast

Why did the construction of the Aswan High Dam on the River Nile cause sediment volume to fall?   p136

Describe and explain how the Akosombo Dam in Ghana has reduced sediment and increased erosion.

Briefly describe how a coastlines erosion can be measured Briefly describe how a coastlines erosion can be measured. You may bullet this detail with older methods and new technology.   Skills focus – p137

Looking at the maps 10.11, describe the differences between 1940 and 2015   Skills focus - 137
