Across
- 3. a planet orbiting in the inner part of the Solar System
- 8. a white band in a Jovian planets atmosphere
- 9. greenhouse effect in which heat trapping grows as temperature rises so the plantes atmosphere rises
- 12. the distance from an astronomical body at which its gravitational force can pull apart another astonomical body
- 15. the breaking apart of a molecule by intense radiation
- 17. a type of meteorite containing many tiny spheres of rocky or metallic materia stuck together by carbon rich material
- 18. a dark band in a Jovian planets atmosphere
- 21. a meteorite containing small spherical grains called chondrules
- 24. cliffs formed where the crust has shifted that run for hundreds of kilometers across a planets/moons surface
Down
- 1. a meteorite lacking chondrules, associated with larger bodies whose gravity and internal heating has cause them to differentiate
- 2. a small spherical gran embedded in a meteorite
- 4. numerous small, icy object orbiting in the outer part of the Solar Syatem beyond the orbit of Neptune
- 5. a small body with a tiny and icy core and a tail of gas and dust
- 6. regions in the asteroid belt with fewer than the average number of asteroids resulting from the gravitational force of Jupiter removing ateroids
- 7. a condition in which the repetitive motion of one body interacts with the repetitive motion of another so as to reinforce the motion
- 10. the passage of a celestial body suh as a planet across the face of a larger body such a star
- 11. planet that doesnt orbit our Sun
- 13. a numeral expression for the approximate distances of most of the planets from the Sun
- 14. a planet that grew largely by gravitational attracting gas from the disk of gas out of which planetary systems form
- 16. a vast region in which comet nuclei orbit
- 19. a region from which some coments come; extends from the orbit of Neptune
- 20. by their gravitational attractions prevent particles in a planets rings from spreading out and dispersing
- 22. a stream of ionized particles evaporatd from a comet and then swept away from the Sun by solar wind
- 23. a small, generally rocky, solid body orbiting the Sun
- 25. the gaseous atmosphere surrounding the head of a commet
