front 4 A set of waves are moving from east to west. Assuming the boat is in deep water, which of the following would describe the motion of a boat during the passage of these waves? | back 4 The boat would move up and down in the water. |
front 5 Which of the following statements describe what happens to sediment when a longshore current meets a jetty? | back 5 Sediment is eroded on the downcurrent side of the jetty because water is starved of sediment in this location. -Sediment is deposited on the upcurrent side of the jetty because water moves slower in this location. |
