Across
  1. 1. the shape of the moon when less than half of its visible surface is illuminated by the Sun
  2. 5. eclipse occurs when the Moon passes between the Sun and Earth, blocking the Sun's light and casting a shadow on Earth
  3. 7. the orbital motion of a celestial body, like a planet, around a central object, such as a star
  4. 9. This phase marks the point in the lunar cycle when the Moon is one quarter of the way through its orbit around Earth. It's also known as a Half Moon.
  5. 11. the flattened oval shape that planets and other celestial bodies follow when orbiting a star (like the Sun)
  6. 13. the different shapes or illuminated portions of the Moon as seen from Earth as it orbits the Earth
  7. 15. a point in time when a planet's poles are most inclined toward or away from the star it orbits, resulting in the longest and shortest days of the year
  8. 17. a lunar where the entire illuminated side of the moon is visible from Earth
  9. 20. a planet's spinning movement around its axis, an imaginary line passing through its center
Down
  1. 2. made up of rock chips, mineral fragments, impact and volcanic glasses and a peculiar component only found on the Moon
  2. 3. large, dark, basaltic plains on Earth's Moon, formed by lava flowing into ancient impact basins
  3. 4. the illuminated portion of the moon is decreasing, moving from a full moon to a new moon
  4. 6. the shape of the moon that is described as round and is between half full and full
  5. 8. the imaginary plane defined by Earth's orbit around the Sun
  6. 10. the cyclical rise and fall of sea levels, primarily caused by the gravitational pull of the Moon on Earth's oceans, and to a lesser extent, the Sun
  7. 12. a lunar phase where half of the Moon's surface appears illuminated from Earth. This occurs roughly one week after the Full Moon
  8. 14. a point in time when a planet's subsolar point (the point on the planet directly facing the sun) passes through its equator
  9. 16. refers to its overall shape, which is roughly round
  10. 18. eclipse occurs when the Earth passes directly between the Sun and the Moon, causing Earth's shadow to cast upon the Moon,
  11. 19. the moon's illuminated portion is growing larger, transitioning from a new moon to a full moon
  12. 21. the lunar phase when the Moon is between the Earth and the Sun, causing the side of the Moon facing Earth to be unlit, making it appear dark or invisible from Earth
