This chapter focuses on the interactions between oceans and coastal places. A coast is the area where the land and the sea meet. In this chapter, the student will learn about the coastal environment and the factors that affect the coastal landscape such as lithology properties, geological structure, processes, sea-level changes, human impacts and ecosystem types. The first section of the chapter also explores concepts and terminologies such as waves, wave refractions, longshore drift, tides, sediment supply, lithology, subaerial and wave processes and vegetation.

There is also a discussion on the types [abrasion, solution, quarrying, attrition] and features of erosion. Cliffs are shaped through erosion and weathering and stacks are formed over time by wind and water, Through the process of coastal geomorphology. Finally the chapter ends with the features of deposition, the advancing and retreating coastlines and the role of coastal processes, wind and vegetation in sand dune development. There is an interesting case study about the Palisadoes in Jamaica that will give more clarity about the issues discussed in the chapter.
