fold mountains form
Fold mountains form.
Shale is made from layers of mud and clay pressed together. :)
New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.
A bend in rock layers created by pressure is called folding. It refers to a ductile behavior in which planar or flat layers of rock bend in response to stress.
Seasonal, cyclical, or other event based depositions of sediment are called strata.
If the situation is as simple as the one you have stated, it isn't difficult. Meanwhile, many faults displace laterally, either in compression or tension so that it can appear that younger rocks overlie older ones. See the law of super-position. Compressive faults generally force younger rocks below older, but not always. See subduction zones. Then see ophiolite suites.
it forms a sedimentary rock
read it on a book:)HAHAHAHA
Compression.
The compressional stress can overcome the strength of the cementing material, or fracture the bonds between the crystalline structure of the rock.
When layers of rock bend downward, the resulting fold is a syncline.

Tilting and folding of rock layers due sinking, uplifting, stretching, or compression of the crust usually from plate movement.
The layers of rock are different thicknesses because of the way the sediments are formed and squashed together
Aquifers are permeable layers of rock that have non permeable layers of rock under them so water remains in the permeable layers
the way geologist know that rock layers are undisturbed is the rock layers are folded
Gaps in rock layers that develop when agents of erosion remove existing rock layers are known as unconformities.
the sinking of the rock layers is called subsidence
