Phases of the Moon starts at 6 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Phases of the Moon.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A student observes the Moon and notes that it is a thin crescent visible just before sunrise. Which phase is the Moon in?
Arrange the following phases in the correct order starting from New Moon:
(1) First Quarter
(2) Full Moon
(3) New Moon
(4) Third Quarter
Calculate the angular distance the Moon travels in its orbit during one synodic month. (Assume a full circle is 360 degrees.)
Calculate the number of lunar phases that occur in one synodic month.
Describe how the Moon's phases would appear if you were standing on the surface of the Moon looking at Earth.
Describe the difference between a synodic and a sidereal month.
Describe the position of the Sun, Earth, and Moon during a first quarter Moon.
A student observes the Moon and notes that it is a thin crescent visible just before sunrise. Which phase is the Moon in?
Which of the following best describes a third quarter Moon?
(1) The right half is illuminated as seen from the Northern Hemisphere.
(2) The left half is illuminated as seen from the Northern Hemisphere.
(3) The entire Moon is illuminated.
(4) The Moon is not visible.
Which of the following best describes why the Moon exhibits phases as seen from Earth?
(1) The Moon changes shape as it orbits Earth.
(2) The Moon moves into Earth's shadow.
(3) The relative positions of the Sun, Earth, and Moon cause different portions of the Moon's sunlit side to be visible from Earth.
(4) The Moon emits its own light.
Which of the following is NOT a phase of the Moon?
(1) Waxing Crescent
(2) Waning Gibbous
(3) Solar Crescent
(4) First Quarter

(1) The Moon is more than half illuminated and increasing.
(2) The Moon is less than half illuminated and increasing.
(3) The Moon is more than half illuminated and decreasing.
(4) The Moon is completely dark.

Fill in the blank: The phase of the Moon when less than half of the Moon is illuminated and the illumination is increasing is called __________.
Fill in the blank: The phase of the Moon when more than half but not all of the Moon is illuminated and the illumination is decreasing is called __________.
Fill in the blank: The time it takes for the Moon to complete one orbit around Earth with respect to the stars is called the __________ month.
True or False: The Moon's orbit is perfectly circular.
True or False: The Moon's phases are caused by Earth's shadow falling on the Moon.
True or False: The Moon's phases repeat in a predictable cycle.
True or False: The phases of the Moon are the same for observers in both the Northern and Southern Hemispheres.
