Which of the following are true about synclines (select all that apply)?


AThe beds in the center are oldest
BThe beds in the center are youngest
CThe beds dip away from the hinge
DThe beds dip towards the hinge
EThey are formed by compressional forces

Verified Answer :

Final answer:

In a syncline, the youngest rock layers are located at the center, with beds dipping towards the hinge of the fold. These geological structures are formed by compressional forces. Thus, the correct statements are about the youngest beds, their dip direction, and the forces involved in their formation.


Explanation:

Understanding Synclines

In geology, a syncline is a type of fold that occurs in rock layers. To discuss the statements provided about synclines, we can evaluate their accuracy as follows:

  1. The beds in the center are oldest: False. In a syncline, the younger layers are typically found in the center of the fold.
  2. The beds in the center are youngest: True. The younger rock layers are located at the core or center of a syncline.
  3. The beds dip away from the hinge: False. In a syncline, the beds dip towards the hinge or axis of the fold.
  4. The beds dip towards the hinge: True. This is characteristic of synclines, where the layers curve downward towards the center.
  5. They are formed by compressional forces: True. Synclines are created as a result of compressional forces that cause the Earth's crust to fold.

Therefore, the correct answers are:

  • b) The beds in the center are youngest
  • d) The beds dip towards the hinge
  • e) They are formed by compressional forces
