For a 4:13 minutes advent to these ideas see https://www.youtube.com/watch?v=rc3da3-znK4. Follow to the principle of initial Horizontality, sediments are deposited horizontally. After they have been transformed into rock, strata may become tilted or folded by assorted tectonic movements. However, this principle basically says that "tilted or urgent layers used to it is in flat”.

You are watching: What are two of the principles of stratigraphy
So ... Which rocks to be deposited first?

?Rocks in ~ the peak of the bluff?Rocks in ~ the bottom of the bluff near the man?Left most layers?Right most layers?Needs more information?It won"t be possible to know.

Next (still In clearly shows Geology) - tilt your model.

discover use of the "tilt" tool, then make the tilt between 45 and 90 degrees. QUESTION: What default edge does the “dip” tool begin with?
While adjusting "tilt": What does a 90 level dip angle cause beds come do? If girlfriend are puzzled by the "tilt" (or dip) tool, see the fourth Youtube video above. Recall the in the "tilt" tool, the red "sheet" represents the angle that will be used when friend click the "Add new tilting event" button.
In visible Geology, click the "topography" tab and select "valley", "mountain", "cliff" etc. Come see exactly how the ground"s topography affect what trends you would check out if you could stand top top the geological scenario you simply made. The 3rd principle, the rule of Lateral Continuity, says that a stratum (layer) of sedimentary rock will proceed in all directions till it thins, qualities into another type of sediment, or comes versus the sheet of the depression right into which the is gift deposited. Which two measures would you use to create the simplest feasible simulation of sedimentary great continuing throughout an eroded valley?
