Go to the picture on this web link http://pubs.usgs.gov/circ/c1075/norfolk.html (the small version of this picture is also part of the previous link). This picture shows the effect of groins on a sandy beach. Based on the areas of sand accumulation and erosion around each groin, what is the direction of longshore current and longshore drift? From the upper left side to the lower right or from the lower right side of picture toward the upper left? Sea level rise is dangerous to coastal communities because it results in increased erosion of sandy coasts, greater potential for inland flooding and possible inundation of low-lying coastal areas. List two human activities which increase the likelihood of sea level rise.
