| 11. | A positive gravity anomaly may be an igneous intrusion, a negative anomaly a salt dome or void.
|
| 12. | Positive gravity anomalies result from the relatively low flexural strength of the lithosphere during the beginning of rifting.
|
| 13. | However, there are other negative gravity anomalies nearby which are not believed to be related to the impact event.
|
| 14. | Approximately 45 percent of the 410 mean free air gravity anomaly values were determined directly from observed gravity data.
|
| 15. | By measuring gravity anomalies, GRACE shows how mass is distributed around the planet and how it varies over time.
|
| 16. | When they tested the machine, Fiddleford got sucked by a gravity anomaly in the machine but Ford rescued him.
|
| 17. | Evidence for the impact origin of the crater includes shocked quartz, a gravity anomaly, and tektites in surrounding areas.
|
| 18. | Likewise over most peaks of the Axial Zone, a negative gravity anomaly can be detected which slowly disappears to the east.
|
| 19. | You have this elevated ridge axis that acts like a mass excess, and ordinarily it would create a positive gravity anomaly,
|
| 20. | Failing that, if the community feels that it is worthwhile, it could be moved to List of gravity anomalies, and refactored.
