World-building is an important part of science fiction writing. You can’t make a world without geographical setting, political environment, socio-historical backdrop, and so on. What about the geological history of a planet or region? Back in the 1800s, the discovery of a past that included Ice Ages, Dinosaurs, and pre-life epochs and eons captured world imagination. But do such discoveries impact modern day stories or events?
Write a few words on how some component of geological history might be a significant element of a science fiction story.
This is intended as a discussion area for the college course “Earth Science Essentials for the Science Fiction Writer”, beginning in Spring 2016, but, please, post some thoughts for the students to consider!
