Knowing whether a fund manager or broker is doing a good job can be a challenge for some investors.It's difficult to define what good is because it depends on how the rest of the market has been performing.When we put both absolute and relative time together, we create a geologic time scale.Rocks relate to events in Earth's history, and we can use them to put together a timeline that shows us both the order of events as well as when and for how long they occurred. We have over 200 college courses that prepare you to earn credit by exam that is accepted by over 1,500 colleges and universities.For example, 60 million years is a measure of absolute time. These are numerical representations of time, and they give us specific points of reference.We have a long record of events in absolute time but much of that occurred before humans were on Earth to write it down.So instead of human records, geologists use techniques such as radiometric dating.These processes involve sampling rocks and determining how old they are from their rate of decay.

Relative time, also called chronostratic time tells us when events occurred relative to each other.Since absolute time gives us points of reference, it helps calibrate relative time, also called chronostratic time ('strata' means 'layers').Here, we are looking at events relative to other events.Try it risk-free You may not associate geology with time, but the former greatly depends on the latter.
