Geologic Timescale

Topics can be covered in chronological order, from the formation of the Solar System to the current Industrial Period. Most courses only focus on part of Earth's history.

This structure has the advantage of simplicity, and helps students to connect sequential events through cause and effect.

Suggestions for Teaching



Not all time units will receive equal coverage. Some may not be covered at all.


Below are web resources that will prove very useful to anyone teaching the geologic timescale, even if the course is not organized around it.
