8th Space

3. season in which Earth is tilted toward the sun resulting in more daylight and higher temperatures
9. the path an object, such as a planet, takes as it revolves around another object
10. an increasing amount of visible light on the moon's surface (light on the right)
11. turning or spinning on an axis
13. the Earth is not tilted away or toward the sun, equal day and night and moderate temps
15. one of the two inventors of a diagram charting brightness and temperature of stars (other is Russel)
16. the tide that occurs when ocean water is at its lowest level
17. moon phase where no reflected light from the sun is seen

1. equal day and night (happens twice a year)
2. the action of one object moving completely around another in an orbital path
4. moon phase where less than half of the moon is visible from the Earth (waxing or waning)
5. an imaginary line drawn around the Earth that divides it into northern and southern hemispheres
6. moon phase where more than half of the moon is visible from the Earth (waxing or waning)
7. the tide that occurs when ocean water is at its highest level
8. a decreasing amount of visible light on the moon's surface (light on the left)
12. an imaginary line that runs through both poles of a planet
13. marks the longest or shortest day of the year (most or least sunlight)
14. moon phase where 100% of the moon is visible from Earth
18. the season in which Earth is tilted away from the sun resulting in less daylight and lower temperatures
