Option #1: Coastlines

The coastlines of the world are impacted constantly by waves, currents, and tides. Choose your favorite coastline (or least favorite) and describe how it is affected by those factors. You should include introductory information about how those processes are formed. Be sure to include their influence on climate, since we will discuss that next week.

Your paper should meet the following requirements:

• Be 3-4 pages in length
• Cite 1-2 outside sources
