What do the letters B on the diagram represent? 03) (1 pt.) What does the red letter C on the diagram represent? 04) (1 pt.) What does the red letter D on the diagram represent? 05) (1 pt.) How deep beneath the wave tops would you have to dive to in order to feel undisturbed water if the wavelength is 46 m? 06) (1 pt.) At what water depth will a wave begin to feel the ocean floor if it has a wavelength of 52 m? 07) (2 pts.) As waves approach a shore, they begin to break when the water depth is 1/20 th of the wavelength. If you cannot swim, would it be safe to walk out to where waves with a wavelength of 60 m are breaking? (1 pt.) Explain your answer (1 pt.) . Ocean tides video 08) (1 pt.) Roughly how high are the high tides at that location? Give the answer in feet. 09) (1 pt.) How many high tides and low tides occur daily at this location? 10) (1 pt.) About how high is one story in a building? (If you don’t already know this, look it up online.) 11) (1 pt.) If there were an apartment building sitting on the sea floor at the location shown in the video you just watched (“Spring Tide Timelapse, Halls Harbour HD”) about how many stories would be flooded at high tide? Ocean currents 12) (3 pts.) What do the warm currents have in common? Mention where they are located relative to the continents (2 pts.) as well as the direction in which they flow (1 pt.) 13) (3 pts.) What do the cold currents have in common? Mention where they are located relative to the continents, (2 pts.) as well as the direction in which they flow (1 pt.) Refer to the “Map of Ocean Gyres” in D2L, as well as your textbook Figure 15.2 to fill in the following table. (1 pt. each cell = 24 pts.) • Col 1: Find the gyre # on the “Map of ocean gyres” (shown as a large green number) • Col 2: Look at the map to determine the direction each gyre flows in. (CW = clockwise, CCW = counterclockwise.) • Col 3: Find the name of each gyre on Figure 15.2 of your textbook. • Cols 4–7: Refer to “Map of ocean gyres” to find the name of the current that goes from the east toward the west (col. 4) the name of the warm current (col 5), the name of the current that goes from the west toward the east (col 6), and the name of the cold current (col 7.) Gyre # Flow CW or CCW Gyre name Name of east to west current Name of warm current Name of west to East current Name of cold current 1 2 3 4 5 Shoreline water movements 14) (2 pts.) Which way is the beach drift moving: north, east, south or west?
