INTRODUCTION
In this module you learn about some fundamental concepts of coastal environments. Topics covered include coastal erosion and deposition processes and features, the tides, and jetties. The module starts with four opening topics, or vignettes, which are found in the accompanying Google Earth file. These vignettes introduce basic concepts and tools on which geographers rely. Some of the vignettes have animations, videos, or short articles that will provide another perspective or visual explanation for the topic at hand. After reading the vignette and associated links, answer the following questions. Please note that some links may take a while to upload based on your internet speed.
