Answer to Question 1

In a plunging anticline, all rock layers dip away from the fold axis, and the oldest rocks are in the
center of the fold with younger rocks on the outside. In a plunging syncline, all rock layers dip toward
the fold axis, and the youngest rock layers are found in the core.



Answer to Question 2

The Bighorn Mountains rose vertically along a fracture. The fracture did not penetrate to the surface,
so as uplift of the mountains proceeded, the near-surface rocks were bent so that they now appear to be
draped over the margin of the uplifted block.

Did you know?

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
