| 2009-07-26 | Bob | 9 | 10 | 10 | 10 | Yes | Thank you Dr. Bell. My question wasn't sufficiently specific. It was in reference to the semi-circular shape of entire length of the Niagra Escarpment from the western shore of Lake Michigan running northeast to the Upper Peninsula, then southeast through Southern Ontario and ending south of Lake Ontario. Regards, Bob |

| 2009-07-07 | Brad | 10 | 10 | 10 | 10 | Yes | Thanks for the quick and concise answer! You answer confirmed my suspicions. Thanks for sharing you expertise. |
| 2009-07-05 | Tom | 10 | 10 | 10 | 10 | No | Thank you for your reply. It was exactly what I was hoping for. As I'm sure you know, debating someone about the moon landings is a bit like talking to a religious zealot, there's unsually no point because nothing you say will ever change their views. However, this particular co-worker has in the past shown an ability to absorb new information and adjust his opinions accordingly, so I thought I'd give it a shot. I figure that the rocks are my best bet. I knew that Earth's magnetic field, atmosphere, and geological activity, would all have a measureable impact on rocks, and that therefore any rocks that come from the moon, which lacks all of those elements, would have be to easily identifiable. I just didn't know the details. Thanks again for the information. |
| 2009-06-30 | Tony | 10 | 10 | 10 | 10 | Yes | Thanks for the consise answer |

| 2009-01-26 | Heidi | 10 | 10 | 10 | 10 | No | thank you! It has been a mystery to me. Some of the rocks are hollow with something inside, some look like caves in tiny form. Thank you |
