Question

1. base your answer to the following question on the graph below and on your knowledge of earth science.

the graph shows the tidal range (the difference between the highest tide and the lowest tide) recorded in minas basin, nova scotia, during november 2007. the phase of the moon on selected days is shown above the graph. the dates that the moon was farthest from earth (apogee) and closest to earth (perigee) are indicated under the graph.
november 2007 tidal range - minas basin, nova scotia
the next first - quarter moon after november 17 occurred closest to
(1) december 9 (2) december 14 (3) december 17 (4) december 24

1. the diagram below represents four positions of the earth as it revolves around the sun.

The lunar cycle (time between identical moon phases) is ~29.5 days. The first-quarter Moon is on November 17. Adding ~29.5 days: November 17 + 29 days = December 16, which is closest to December 17.
