Psychology. This has been well studied and there is all hocus pocus. No dowser goes hunting for water on the top of a mountain or the edge of a cliff or in a volcano. Anywhere else you look usually has water at SOME depth. It doesn't take witchcraft.
Forces bend flex.
In the absence of external forces, there's nothing to cause it to bend.
Tension
I will cause it to refract.
Yes, they make light bend inwards towards a focus point.
Metamorphic rock i think?
Layers of rocks can curve downward due to tectonic forces. When two tectonic plates collide, the pressure and compression can cause the rocks to fold and bend. This folding can create downward curves known as synclines, where the youngest rocks are exposed in the center and older rocks are found on the sides.
Forces bend flex.
The word is "droop."
Syncline.
Flex your foot
...known as syncline
Syncline
Plate movemens sometimes cause the crust to warp, or bend, downward. The result is a basin. A basin is a broad, bowl-shapped valley. For example, the central valley of California is a huge basin with the sierras and coast ranges on either side. As these mountains rose, the curist forming the central valley's floor was bend downward.

A Syncline is where lays of rock bend downwards and then curve up. An Anticline is the opposite: layers of rock bend upwards and then down.
