question 1(multiple choice worth 5 points)
(06.03 mc)
the diagram below shows four coastline locations on earth with respect to the moon at a given time.
image of moon and earth with points a, b, c, d
in this current position, which coastline(s) are experiencing a daily low tide?
○ only a
○ only b
○ both a and c
○ both b and d

Explanation:

Tides are caused by the gravitational pull of the moon (and sun). High tides occur at locations facing the moon (A) and directly opposite (C) due to gravitational forces and inertia. Low tides occur at the locations perpendicular to the moon - Earth line, which are B and D. So both B and D experience low tides.

Answer:

D. Both B and D
