Question: 1 / 400

What occurs to the dip as one moves away from the fold axis line?

Decreases laterally

As one moves away from the fold axis line in a geological fold, the dip of the rock layers decreases laterally. This is due to the nature of folding, where the greatest dip is typically found at the fold axis, which represents the tightest curvature of the fold. As you move outward from this axis towards the limbs of the fold, the angle of tilt of the rock layers becomes less steep, hence the dip diminishes.

This behavior is intrinsic to the geometry of folds – the central part tends to be more tightly bent, resulting in a steeper dip, while the outer sections are more gently inclined. Understanding this concept is essential for interpreting geological structures, as it helps in predicting the behavior of rock layers in folded terrains.
