Largely through the discipline of geology, science allows us to push back the mists of time and peer into a past measured in billions of years, and aptly referred to as 鈥淒eep Time.鈥� Climb on board!

Certificate earners demonstrate proficiency through a few short assessments and discussion prompts and are prepared to teach or apply the material....

great course, just one star less because it did not talk about other mountains or other geological items, I would have loved to hear about the Jura, Alps, etc.
