Which of the following decreases beach erosion without the construction of protective structures? a. seawall c. groin b. beach nourishment d. breakwater 16. Which of the following is designed to prevent or slow shoreline erosion? a. groin c. seawall b. beach nourishment d. all of the above 17. Which of the following structures is built to protect boats from large breaking waves? a. jetty c. breakwater b. groin d. seawall 18. Which of the following describes the movement of sand parallel to the shore? a. It may create spits. b. It is achieved by longshore currents. c.

Waves along the shoreline are constantly eroding, transporting, and depositing. 0. When waves reach the shallow water of a smoothly sloping bottom, the wave crests are and tend to line up nearly parallel to shore. 1. Spits and bars are depositional features, while sea arches and sea stacks are features.. A(n) is a barrier built at a right angle to the beach to trap sand that is moving parallel to the shore.
