Big Ideas
- The order of rock layers can be established without knowing their absolute ages by applying principles of relative dating, stratigraphy, and fossil evidence.
- Understanding the sequence of geologic events and the evolution of life on Earth depends on interpreting rock records and fossil distribution.
