- 1. When the Moon appears to get smaller
- 4. When the Moon appears to get bigger
- 8. The force of gravity between two objects like the Earth and the Sun and the Earth and the moon.
- 13. of the moon the progression of changes in the moon's appearance during the month
- 14. the phase of the moon in which only a curved edge of the moon's side that faced earth is illuminated which lasts about 6 days, can be a small sliver or almost a quarter moon.
- 15. The phase of the Moon when half of the Moon's near side is sunlit.
- 16. An imaginary line that passes through Earth's center and the North and South poles, about which Earth rotates
- 17. The (tilt) angle that a planet's axis is tilted from vertical
- 18. The path of an object as it revolves around another object in space
- 19. A natural satellite that revolves around a planet.
- 20. the time required for Earth to rotate once on its axis
- 21. main source of energy for life on earth
- 22. moon phase when the entire side facing Earth is illuminated.
- 24. The season experienced when the earth's axis is tilted TOWARD the sun
- 26. The partial or total blocking of one object in space by another
- 28. a fixed luminous point in the night sky that is a large, remote incandescent body like the sun.
- 29. the regular rise and fall of the ocean's surface influenced by the moon's gravity pulling on earth
- 31. A large body in space that orbits a star and does not produce light of its own
Down
- 2. when the size of the illuminated portion of the moon is greater than half but not a full moon, lasts about 6 days can be almost all white or just a little more than 1/2 white
- 3. the time required for the Earth to orbit once around the sun
- 5. when the side of earth that you are on is facing away from the sun
- 6. eclipse. the blocking of sunlight to the moon that occurs when Earth is directly between the sun and the moon
- 7. The season experienced when the earth's axis is tilted AWAY from the sun
- 9. A sequence of phases of the moon as it revolves around the Earth once every 27.3 days.
- 10. are caused by the tilt of the earth's axis & the revolution around the sun
- 11. half of the earth. The earth is split between these two.
- 12. Moon phase that occurs when the Moon is between Earth and the Sun, at which point the Moon cannot be seen because its lighted half is facing the Sun and its dark side faces Earth.
- 23. The tilt of the Earth means the Earth will lean towards the Sun (Summer) or lean away from the Sun (Winter) 6 months later. In between these, Spring and Autumn will occur. The Earth revolves around the Sun.
- 25. The movement of an object around another object
- 27. The spinning of Earth on its axis
- 30. eclipse. Occurs when the Moon passes directly between the Sun and Earth and casts a shadow over part of Earth
