Most rock layers (and ALL sedimentary layers) start out flat. Folding changes the angle of lie (even to perpendicular and beyond).
A sill is formed when magma is forced into layers parallel to the surrounding rock layers. Sills are characterized by their tabular shape and are often found intruding between rock layers.
When rock layers bend due to stress, they undergo deformation through a process known as folding. This can result in the formation of structures like anticlines (upward-arching folds) and synclines (downward-arching folds). The degree of bending can vary from gentle folds to tight, complex structures depending on the type and amount of stress applied.
Lava that cuts across rock layers hardens to form a feature called a Dike.
A trough-like fold of rock strata is known as a syncline. Synclines are downward-arching folds where the youngest layers are located in the center of the fold and the oldest layers are along the outer edges. They are typically U-shaped in appearance.
Anticlines are commonly formed by the upfolding or arching of rock layers. These geological structures are characterized by convex-upward folds in the Earth's crust. Anticlines often trap oil and gas within their folds, making them important in petroleum exploration.

Sedimentary rock, like limestone, is formed in layers.
A fold in geology is a bend in rock layers caused by tectonic forces. The two main types of folds are anticlines (upward-arched rock layers) and synclines (downward-arching rock layers).
An anticline is a fold in which the older layers of rock are on the inside. A syncline is a fold in which younger layers are on the incline. Usually anticlines bow upwards while synclines bow downwards.
The land where the rock was formed was underwater when the rock was formed. Over the years layers of Sediment sank to the bottom. Pressure formed the sediments into rock.
An upwards arching layer of rock is known as an anticline.
A sill is a slab of volcanic rock formed when magma squeezes between layers of rock. It is typically horizontal and parallel to the surrounding rock layers. Sills are distinguishable from dikes, which cut across the rock layers.

"Folding" is the term that describes the bending of rock layers due to stress.There are different types of Folds and these include:Anticlinal Folds: This is when the rock layers have an upward-arching folds.Synclinal Folds: This is when the rock layers have a downward, trough-like folds.Monoclinal Folds: This is when both rock layers ends are horizontal.
