Across
- 2. most likely exists at the poles shadowed in deep craters
- 4. many other solar activities are due to differential rotation
- 6. circular features formed by meteorite impacts
- 8. dark areas on the surface that are ancient basaltic lava flows
- 10. the Earth is positioned between the Moon & Sun
- 12. Moon is slightly egg-shaped
- 13. theory - Moon formed far away and was caught by Earth’s gravity
- 14. orbit to rotation ratio 1:1
- 16. theory Moon formed separately near Earth
- 17. Moon’s rotation is identical to its orbit around Earth - 27.3 days
- 18. pulverized meteorite ejecta or regolith
- 19. the Moon is positioned between the Earth & the Sun
Down
- 1. Moon’s gravity causes a tidal drag on Earth’s spin
- 3. the continuous flow of charged particles (ions, electrons, and neutrons) that comes from the Sun in every direction
- 5. lighter areas that are mountainous
- 7. ditches where molten lava flowed
- 8. largest impact crater on the Moon (10
- 9. radiation from the surface of the Sun, which is the portion of the Sun we see
- 11. from inside the Sun causes the photosphere to be subdivided into 1000-2000 km cells
- 15. thin orange-red gaseous layer just above the photosphere
