​Objectives:

​

1. Distinguish between numerical dates and relative dates;

​

2. Infer that rock layers are formed due to geologic processes

according to the principles of relative dating;

3. Elaborate the significance of the geologic time scale in determining

the characteristics of organisms in a particular time period.
