Relative age dating and absolute age dating
An imaginary cross-section, showing a series of rock layers and geological events (A-I). A few days ago, I wrote a post about the basins of the Moon -- a result of a trip down a rabbit hole of book research.
We have no idea how much older thing B is, we just know that it's older.is simple, intuitive, and is the basis for relative age dating.It states that rocks positioned below other rocks are older than the rocks above.Long before I understood what any of it meant, I'd daydream in science class, staring at this chart, sounding out the names, wondering what those black-and-white bars meant, wondering what the colors meant, wondering why the divisions were so uneven, knowing it represented some kind of deep, meaningful, systematic organization of scientific knowledge, and hoping I'd have it all figured out one day.This all has to do with describing how long ago something happened. There are several ways we figure out relative ages.
