2. moon - the moon's phase when it is in conjunction with the sun so that its dark side is toward the earth
4. moon - A quarter moon occurs when we see the Moon half illuminated by the Sun, and half enshrouded in darkness. Since the illuminated side points towards the Sun, it tells astronomers that the Moon and the Sun are separated by 90-degrees from our perspective here on Earth.
5. - each of the four divisions of the year (spring, summer, autumn, and winter) marked by particular weather patterns and daylight hours, resulting from the earth's changing position with regard to the sun.
8. moon - marked by convexity or swelling of the moon or a planet : seen with more than half but not all of the apparent disk illuminated.
9. - to cause to lean, incline, slope, or slant.

1. moon - A crescent is a thin, curved shape that's thicker in the middle and tapers to thin points at each end, like the little sliver of moon you might notice in the sky.
3. - The phases of the Moon are the different ways the Moon looks from Earth over about a month. As the Moon orbits around the Earth, the half of the Moon that faces the Sun will be lit up. The different shapes of the lit portion of the Moon that can be seen from Earth are known as phases of the Moon.
6. - the curved path of a celestial object or spacecraft around a star, planet, or moon.
7. moon - the phase of the moon in which its whole disk is illuminated.
