Geologic Time Scale Representation
The geologic time scale can be represented as a football field, providing a visual representation of the vastness of geologic time and the relative durations of different eras and periods.
Starting at the goal line, which represents the present day, the football field extends backward in time toward the end zone, representing the beginning of the Earth’s history approximately 4.6 billion years ago.
Eras and Periods on the Football Field
Eras, Geologic time football field answer key
- Precambrian Era:Goal line to the 50-yard line (88% of Earth’s history)
- Paleozoic Era:50-yard line to the 35-yard line (375 million years)
- Mesozoic Era:35-yard line to the 15-yard line (186 million years)
- Cenozoic Era:15-yard line to the end zone (66 million years)
Periods
Each era is further divided into periods, represented by smaller segments of the football field.
