Which one of the following statements is not correct?
General KnowledgeGeography
- APosition of the Sun, Earth and Moon in a straight line of 180° angle is known as syzygy.
- BSyzygy conjunction causes solar eclipse.
- CSyzygy opposition causes lunar eclipse.
- DSyzygy conjunction occurs at the time of perihelion only.
Explanation
Syzygy is the straight-line alignment of Sun, Earth and Moon: conjunction (new moon) can cause a solar eclipse and opposition (full moon) a lunar eclipse — so (a), (b) and (c) are true. Statement (d) is not correct because conjunction recurs every synodic month (about 29.5 days), not only at perihelion, when Earth is nearest the Sun.
