Question

what information does the geologic time scale provide?
explanation of how organisms interact with one another
places where dinosaurs roamed on earth
reasons why organisms evolve into different species
information about when plants first appeared

Explanation:

The geologic time scale is a system of chronological dating that relates geological strata to time. It provides information about the timing of major geological and biological events. It can tell us when plants first appeared. It doesn't directly explain organism - to - organism interaction, where dinosaurs roamed (more a paleontological mapping aspect), or reasons for evolution (which is more about evolutionary theory).

Answer:

information about when plants first appeared
