Across
- 1. A representation or idea used to describe and explain phenomena that cannot be experienced directly.
- 5. The 24 hour period in which the earth completes one full rotation on its axis
- 6. An imaginary line around the Earth that goes exactly midway between the North Pole and the South Pole and divides it into two halves, the north and southern hemisphere
- 7. The hemisphere below the equator
- 8. The path that an object takes in space when it goes around a star, a planet, or a moon.
- 10. The positioning and tilt of Earth relative to the sun results in the most amount of daylight time (summer solstice), or the least amount of daylight time (winter solstice) in a single day
- 12. The circular motion of an object around its center
- 14. When the sun is on the other side of the Earth from you and its light and heat don't get to you. We get day and night because the Earth spins (rotates) on its imaginary axis.
- 15. The circular orbit of one object around another object.
Down
- 2. When you can see the sun from where you are and its light and heat can reach you. We get day and night because the earth spins (rotates) on it's imaginary axis
- 3. Caused because of the tilt and its changing relationship to the Sun. Earth's 4 seasons are Summer, Fall, Winter, and Spring
- 4. The hemisphere above the equator
- 9. Means to be slightly turned. The Earth's axis slightly tilts at 23.5 degrees.
- 11. Occurs when the position of the Sun is exactly over the equator. Occurring twice a year (fall and spring), the hours of day and night are about equal almost everywhere on earth.
- 13. An imaginary line an object turns around
