Question

Which one of the following is true for anticlines but not for synclines? a.The deeper strata are buckled upward along the fold axis. b.The limbs dip or are inclined towards the fold axis. After erosion, c.the younger strata are exposed along the axial region of the fold. d.Some may be asymmetric and some may have plunging axes.

Answer 1

The deeper strata are buckled upward along the fold axis in anticlines but not in synclines.

Step-by-step explanation:

Anticlines are folds that arch upwards, with the oldest rock layers at the center and the youngest rock layers on the outside. The deeper strata are indeed buckled upward along the fold axis in anticlines. On the other hand, synclines are folds that dip downwards, with the youngest rock layers at the center and the oldest rock layers on the outside. The strata in synclines are not buckled upward, but rather, they are buckled downward along the fold axis.

For example, if you imagine folding a piece of paper into a valley shape, with the center of the fold representing the youngest rock layer, you would have a syncline. In this case, the strata in the fold are dipping or inclined towards the fold axis, but they are not buckled upward.

Answer 2

The correct answer is letter A.

An anticline and a fold with its concavity facing downwards, and at its core are older rocks or extracts.

A syncline is a fold with the concavity facing upward, displaying layers that hang toward the center of the structure.
