Do you have a question about Earth's history or geology in general? Send them to Dick Gibson at firstname.lastname@example.org and we'll try to answer them in a future podcast.You can also post your question as a comment at the bottom of this page, and questions that don't demand a longer discussion may be addressed here.
All submissions will be considered but we can't guarantee that they will become podcasts and we also can't provide a definite schedule for the episodes. Podcasts addressing questions will be tagged with "Questions" in the sidebar index.
Thanks for your interest!
