Across
- 4. a period of the year identified by changes in hours of daylight and weather
- 6. each different shape of the Moon
- 7. signature the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light.
- 9. a representation of thinking to help others understand your thinking
- 11. the shape of the Moon just after and just before the new Moon phase
- 14. light-colored areas of the Moon with lots of rough mountains and craters
- 15. spinnin on an axis
- 17. line a bright line of a spectrum, indicating the wavelength of emitted light
- 19. a tool used to study the light spectrum of colors coming from a light source
- 22. a pattern of wavelengths that can identify different kinds of light
- 24. a day of the ear when the Sun's rays shine straight down on the equator
- 25. a change in land created by an impact
- 26. an imaginary line about which a body rotates
- 27. eclipse when Earth is exactly between the Moon and the Sun, and the Moon passes throught the Earth's shadow
Down
- 1. getting smaller
- 2. a day of the year when Earth's North Pole is leaning either toward the Sun or away from the Sun
- 3. a Moon shape that is larger that a first or third quarter Moon, but small than a full Moon
- 4. angle he angle between the projection of sun rays and a line due south or north. It is an angle that is measured on the horizontal plane
- 5. Moon the phase that occurs when the Moon if full
- 7. the angular distance east or west from the Earth's equator
- 8. Star the reference star pointed to the Earth's North Pole
- 10. the imaginary line that runs around the middle of the planet, halfway between the North and South pole
- 12. getting bigger
- 13. light wavelengths of electromagnetic radiation that can be seen by the human eye
- 16. Moon the phase of he Moon that occurs when the Moon is in the directions of the Sun as seen from Earth
- 18. the path one object takes to travel around another object (synonym: orbit)
- 20. eclipse when the Moon passes exactly between Earth and the Sun
- 21. the path one object takes to travel around another object (synonym: revolution)
- 23. the angular distance north or south from the Earth's equator
