40. Base your answer to the following question on the passage and map below and the tide table. The map shows the tidal range (the difference between the highest and lowest tides) in meters for the Bay of Fundy, Chignecto Bay, and the Minas Basin. The table shows the times of high and low tides for Hopewell Cape for August 21 and 22,. 2005. The Bay of Fundy has the Highest Tides on Earth The unique shape of the Bay of Fundy contributes to the extremely high ocean tides experienced there. Frequently described as funnel shaped, the bay gradually becomes more narrow and shallow to the northeast where it splits to form Chignecto Bay and the Minas Basin. The highest tides of the Bay of Fundy are found within these fingers of the bay and are caused by the incoming tides encountering seaward-moving river currents as the bay narrows. The tide height is also affected by the amount of time it takes for high tide to flood the bay. This time is nearly identical from one high tide to the next.
On the grid below, plot with an X the height of the water for each time listed on the tide table. Connect the centers of the Xs with a smooth, curved line.
