Across
- 2. 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.
- 4. The southern of either of the two locations ( North Pole or South Pole ) on the surface of the earth (or of a celestial object) which are the northern and southern ends of the axis of rotation.
- 7. The northern of either of the two locations ( North Pole or South Pole ) on the surface of the earth (or of a celestial object) which are the northern and southern ends of the axis of rotation.
- 12. high or low; the space (usually measured in degrees) between two intersecting lines or surfaces at or close to the point where they meet.
- 13. a single orbit of one object around another or about an axis or center.
- 14. a parallel of latitude on the Earth
- 15. the action of rotating around an axis or center.
- 17. the time or date (twice each year) at which the sun reaches its maximum or minimum declination, marked by the longest and shortest days (about June 21 and December 22).
- 19. the equinox in September, when the sun crosses the celestial equator in a southerly direction.
- 20. an imaginary line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0°.
- 22. a parallel of latitude on the Earth
- 23. the equinox in March, when the sun crosses the celestial equator in a northerly direction, marking the prime meridian of right ascension.
- 24. one of the two polar circles and the most northerly of the five major circles of latitude as shown on maps of Earth.
- 25. each of the two belts of latitude between the torrid zone and the northern and southern frigid zones.
- 26. the solstice that marks the onset of winter, at the time of the shortest day, about December 22 in the northern hemisphere and June 21 in the southern hemisphere.
- 28. the part of the planet that is south of the equator
- 29. the warmest season of the year
Down
- 1. The angular distance either north or south of the earth equator
- 3. the coldest season of the year
- 5. a half of the earth, usually as divided into northern and southern halves by the equator, or into western and eastern halves by an imaginary line passing through the poles.
- 6. the part of the planet that is north of the equator
- 8. the solstice that marks the onset of summer, at the time of the longest day, about June 21 in the northern hemisphere and December 22 in the southern hemisphere.
- 9. the third season of the year, when crops are harvested and leaves fall.
- 10. a star in the northern circumpolar constellation of Ursa Minor.
- 11. Between the tropic of cancer and the tropic of Capricorn
- 12. one of the two polar circles and the most southerly of the five major circles of latitude as shown on maps of Earth.
- 16. an imaginary pole going right through the center of Earth
- 18. the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of approximately equal length (about September 22 and March 20).
- 21. regions of the planet that surround its geographical poles, lying within the polar circles
- 27. the season after winter and before summer, when vegetation starts to appear.
- 28. a ray of sunlight
