Dating sedimentary rock layers dating game theme wav
In this lesson, we'll learn a few basic principles of stratigraphic succession and see whether we can find relative dates for those strange strata we found in the Grand Canyon.
In order to establish relative dates, geologists must make an initial assumption about the way rock strata are formed. sediments, which are deposited and compacted in one place over time.
Back in the lab, we can study the fossil more closely.
Your goal is to study the smooth, parallel layers of rock to learn how the land built up over geologic time.
Now imagine that you come upon a formation like this: What do you think of it? How can you make any conclusions about rock layers that make such a crazy arrangement?
They could be as close as Arizona or as far away as the Gobi Desert in Mongolia!
So that's where the team and I goto places with sedimentary rock.
