Coastlines are the great interface between the 29% of earth’s surface that is land and 71% of earth that is covered by the oceans. Therefore, it is the longest visible boundary on earth. To understand...Coastlines are the great interface between the 29% of earth’s surface that is land and 71% of earth that is covered by the oceans. Therefore, it is the longest visible boundary on earth. To understand the processes that take place at this interface, we must first consider the energetic action at this boundary; namely, waves. The importance of this interface is seen in the study of ancient shorelines, and particularly for natural resources, a process called sequence stratigraphy.
