Which one of the following statements is not correct?
- A.Position of the Sun, Earth and Moon in a straight line of 180° angle is known as syzygy.
- B.Syzygy conjunction causes solar eclipse.
- C.Syzygy opposition causes lunar eclipse.
- D.Syzygy conjunction occurs at the time of perihelion only.
Correct answer
Explanation
The correct answer is D, Syzygy conjunction occurs at the time of perihelion only. This statement is not correct, because conjunction happens at every new moon, about once a month, and has nothing to do with the Earth's closest point to the Sun. Syzygy is the arrangement of the Sun, the Earth and the Moon in one straight line. When the Moon lies between the Sun and the Earth, the position is called conjunction; this is the new moon, and if the alignment is exact a solar eclipse occurs. When the Earth lies between the Sun and the Moon, it is opposition; this is the full moon, and an exact alignment gives a lunar eclipse. Both positions also cause spring tides. Perihelion, the Earth's nearest point to the Sun, comes only once a year, around 3 January. Option A is wrong to pick because it gives the correct meaning of syzygy. Option B is wrong because conjunction does cause a solar eclipse. Option C is wrong because opposition does cause a lunar eclipse. Exam tip: conjunction, new moon, solar eclipse; opposition, full moon, lunar eclipse; both give spring tides.
