Tide Graphing Exercise
|
1. Graph the tidal variation for five consecutive days at your coastal location. You will obtain the information for this from tidal charts. 2. When was the highest tide? 3. When was the lowest tide? 4. Calculate the tidal range. 5. On what days could a person enter a cave if the entrance is three feet above chart datum. Use a line across the graph to answer this question. 6. Give four reasons why it is important to be able to predict the time and height of tides. 7. What is a factor that affects the height of tides? 8. How could you measure the rise and fall of the tides over a 24 hour period. Draw a labeled diagram of your device that will record the vertical rise and fall of the ocean. Graphing Help |
