A Synform fold or Syncline.
A syncline fold has strata on both limbs dipping inward toward the axis. This type of fold is characterized by a trough-like structure where the youngest layers are located in the center. It is the opposite of an anticline fold.
An upward fold in rock that forms an arch-like structure is called an anticline. It is a type of fold in the Earth's crust where the rock layers are bent upwards in a convex shape, with the oldest rocks located at the core of the fold.
A fold is a geological structure where rock layers are bent or curved due to tectonic forces, typically resulting in the formation of ridges and valleys. The oldest rock in the center of a fold is often referred to as the "nucleus" or "core" of the fold and is usually a type of metamorphic or igneous rock that has undergone significant geological processes. In many cases, this oldest rock is referred to as the "axial" or "central" part of the fold. The specific age of the oldest rock can vary widely depending on the geological context and location of the fold.
A cube has 3-fold rotational symmetry, meaning it can be rotated by 120 degrees and still look the same. It does not have 5-fold rotational symmetry because the cube's faces are not oriented in a way that allows for that type of symmetry. The angles between the faces do not align with the requirements for 5-fold rotational symmetry.
Syncline is a type of fold that is created when the crust bends and curves downward. It is a fold that is convex up and has its oldest beds at its core.

A syncline is a downward curving fold in a rock formation, where the strata dip toward the center of the structure. An anticline is an upwardly curving fold, with the strata rise upward toward the center of the structure.

In Geology, using Ramsay's classification scheme for folds, a "parallel fold" is a type 1B fold.
A fold is a geological structure where rock layers are bent or curved due to tectonic forces, typically resulting in the formation of ridges and valleys. The oldest rock in the center of a fold is often referred to as the "nucleus" or "core" of the fold and is usually a type of metamorphic or igneous rock that has undergone significant geological processes. In many cases, this oldest rock is referred to as the "axial" or "central" part of the fold.

The central portion of high curvature on a fold is termed the hinge. It represents the tightest bending or folding point along the fold structure.
