| Question | Answer |
|---|---|
| Rotation | A rotation is a circular movement of an object around a center (or point) of rotation |
| Revolution | the motion of one body around another |
| Axial Tilt | axial tilt, known to astronomers as obliquity, is the angle between an object's rotational axis, and its orbital axis |
| Lunar Eclipse | A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra |
| Solar Eclipse | As seen from the Earth, a solar eclipse occurs when the Moon passes between the Sun and Earth, and the Moon fully or partially blocks ("occults") the Sun |
| Neap Tide | The tide which occurs when the Moon is in its first and third quarter; the effects of the Sun and Moon being partially cancelled out this type of tide is of minimum range |
| Spring Tide | The exceptionally high and low tides that occur at the time of the new moon or the full moon when the sun, moon, and earth are approximately aligned |
| New Moon | new moon is the phase of the Moon when it lies closest to the Sun in the sky as seen from the Earth |
| Full Moon | Full moon is a lunar phase that occurs when the Moon is on the opposite side of the Earth from the Sun |
| First Quarter | Moon phase between the New and Full Moon where exactly half of the side facing Earth is illuminated |
| Third Quarter/Last Quarter | approximately one week after a full moon, when half of the moon's disk is illuminated by the sun |
| Waxing | Have a progressively larger part of its visible surface illuminated, increasing its apparent size |
| Waning | Have a progressively smaller part of its visible surface illuminated, so that it appears to decrease in size |
| Waxing Crescent | The moon appears to be partly but less than one-half illuminated by direct sunlight. Illumination is increasing |
| Waxing Gibbous | A lunar phase or phase of the moon is the appearance of the illuminated portion of the Moon as seen by an observer, usually on Earth Illumination is increasing |
| Waning Crescent | The moon appears to be partly but less than one-half illuminated by direct sunlight. Illumination is decreasing |
| Waning Gibbous | A lunar phase or phase of the moon is the appearance of the illuminated portion of the Moon as seen by an observer, usually on Earth Illumination is decreasing |
| Wave | electromagnetic radiation: radiation consisting of waves of energy associated with electric and magnetic fields |
| Tide | The alternate rising and falling of the sea, usually twice in each lunar day at a particular place, due to the attraction of the moon |
| Umbra | The fully shaded inner region of a shadow cast by an opaque object, esp. the area on the earth or moon |
| Penumbra | The shadow cast by the earth or moon over an area experiencing a partial eclipse |
| Total Eclipse | An eclipse in which the whole of the disk of the sun or moon is obscured |
| Partial Eclipse | an eclipse in which the eclipsed body is only partially obscured |
| Polaris | A fairly bright star located within one degree of the north celestial pole, in the constellation Ursa Minor |
| Seasons | Each of the four divisions of the year marked by particular weather patterns and daylight hours |
