Observation, Evidence, and Geologic Time

Earth scientists build explanations by carefully observing rocks, fossils, and other evidence in the field, then use that evidence to reconstruct events that may have happened millions or billions of years ago. Because Earth is about 4.6 billion years old, this course also introduces geologic time, a timescale far longer than a human lifetime that requires different tools and reasoning than the recent past.
