1) A variety of techniques and efforts are used to stabilize shorelines throughout the world. Discuss these techniques. Are they temporary or permanent? Also, discuss at least two ways in which the development/urbanization of coastal areas contributes to shoreline erosion? (Hint: think about rivers and what they contribute to our beaches. Also, what increases with the creation of roads and rooftops?)
Your response should be at least 150 words in length.
2) The best place to look for crabs is between the high tide and low tide zones (the tidal flat). Knowing this, would you expect to find more crabs during a full moon/new moon or during a quarter moon stage? Explain why.
3) When you are at the beach, you notice that the waves seem to “break” at the same point as they come towards shore. Explain what is happening beneath the surface to cause the waves to break at this point.
