Question

base your answers to questions 29 and 30 on the diagram below and on your knowledge of earth science. the diagram represents the moon at different positions, labeled a, b, c, and d, in its orbit around earth.

1. at which two moon positions would an observer on earth most likely experience the highest high tides and the lowest low tides?

a) c and a b) b and c c) d and b d) a and b

1. during which moon phase could an observer on earth see a lunar eclipse occur?
2. the table below shows tide data for a location on the north shore of long island, in new york state.

based on these data, what is the most likely time of the next high tide?
a) 1:53 p.m. b) 7:40 p.m.
c) 1:53 a.m. d) 7:40 a.m.

Explanation:

Question 29

Spring tides (highest high tides and lowest low tides) occur when the Sun, Earth, and Moon are in a straight line (syzygy). In the diagram, positions \(A\) (new - moon) and \(C\) (full - moon) are in syzygy.

A lunar eclipse occurs when the Earth is between the Sun and the Moon. This happens during the full - moon phase. Among the options, option B represents the full - moon phase (a completely illuminated Moon).

Answer:

A. \(C\) and \(A\)
