1. Glaciation

   • Drowned River Valleys
     • Coastal Plain Estuaries that deal with the waxing and waning of ice sheets
     • Formation: Sea levels fall and the original mouth deepens and widens, when sea levels rise (ice sheet melts), the water floods the existing, now enlarged valley
     • Examples: Delaware and Chesapeake Bay
   • Fjords
     • Flooded Coastal Mountain Valleys found throughout high altitude coastlines, with steep, cliff like sides with winding valleys
     • Formation: alpine glaciers erode bedrock that lies below sea level
     • Examples: Scandanavian Countries (Iceland, Greenland, Chile, Argentina, Canada, and Alaska)
   • End Moraines
