How could you tell an eroded plunging anticline from an eroded plunging syncline? What will be an ideal response?

Question 2

How did the monocline in the Bighorn Mountains in Wyoming form? What will be an ideal response?

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.
