Learning objectives To be able to define the five processes of marine coastal erosion To be able to explain the factors affecting coastal erosion To describe the difference between concordant and discordant . Ms Carr. 5. th. year Geography. Learning Intention. Understand how coastal processes transform the landscape. Examine the landforms created by these coastal processes. FEED. s for these landforms. F. With over four billion people living in coastal areas and the numbers growing rapidly each year, the need to understand and manage these areas is critical. Coastal areas are one of the most dynamic environments on the earth and area being constantly re-shaped by both natural processes and human development. They have both economic and environmental value – and it is these conflicting demands that bring about the need for long-term, sustainable management strategies.. What has caused this?.

Coastal erosion is the endless reshaping of shorelines by waves, currents, tides, storms, ice, rain and groundwater seepage.
