Across
- 1. increase in size, number, or range
- 4. The half of the earth that is above the equator
- 7. moving in the opposite direction the hands of a clock do. In a circular direction, moving left on the top, right on the bottom.
- 9. the measurement of the amount of mass per unit of volume of a substance
- 12. The innermost layer of an atmosphere
- 14. The fourth layer of an atmosphere
- 17. decrease in size, number, or range
- 19. the force exerted by air, on any surface in contact with it
- 20. moving in the same direction the hands of a clock do. In a circular direction, moving right on the top, left on the bottom.
- 21. A figurative line drawn horizontally across the middle of the earth that is equally distant from both the North Pole and the South Pole
- 22. belt around the earth near the equator where ships sometimes get stuck due to windless waters
Down
- 2. the northernmost point of the earth — the uppermost part of Earth’s axis
- 3. The third layer of an atmosphere
- 5. The half of the earth that is above the equator
- 6. The layers of gasses surrounding a planet (or other celestial body)
- 8. a mid-latitude atmospheric circulation cell for weather named by Ferrel in the 19th century
- 10. a sloping position or movement
- 11. The second layer of an atmosphere
- 13. the southernmost point of the earth — the lowermost part of Earth’s axis
- 15. The outermost layer of an atmosphere
- 16. as a result of the Earth rotating on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere
- 18. a large-scale atmospheric convection cell in which air rises at the equator and sinks at medium latitudes, typically about 30° north or south
