Question

How do scientists use relative and absolute dating and the geologic time scale to organize Earth's 4.6-billion-year-old history?

Answer 1

The Earth's crust has different layers of dirt. After many years of study, research and observations scientists were able to associate every layer with an amount of time in history.


So, depending on how deep an artifact is found in the dirt, scientists can locate it in a certain geological period. The deeper it is, the older it is. The closer to the surface, the younger it is.

Hi manugavassi45,

Your Question:

How do scientists use relative and absolute dating and the geologic time scale to organize Earth's 4.6-billion-year-old history?

Answer:

Scientists mostly use geologic times, for example, the ice age or the the dinosaur era. They can use other things and date back to when that happened. For Example when they find fossils from dinosaurs or other extinct animals on the earth. Lots of precious ore and artifacts can be dated back to when there were all those empires.
