Folding
The part of your finger that bends is called the joint, specifically the proximal and distal interphalangeal joints which allow the finger to flex and extend. These joints are made up of bones, ligaments, tendons, and synovial fluid that work together to enable movement.
Autotropic & geotropic
When the Earth's crust bends but does not break, it is called flexural bending or flexure. This type of deformation can occur in response to tectonic forces, leading to the formation of features like folds, fault-related folds, and anticlines.
When a body of rock bends upward into an arch, it is called an anticline. It is a type of fold in the Earth's crust where the oldest rocks are found at the core of the arch. Anticlines are often associated with the accumulation of oil and gas deposits.
Extension. Extension increases an angle, as in straightening a joint. During extension, the knee or elbow are straightened.
Convex when it bends outwards, concave when it bends inwards
When a wave bends around an obstacle, it is called diffraction. This phenomenon occurs when waves encounter an obstacle or aperture that causes them to spread out and bend around the edges.

It is sometimes called the bends
Because they carve the easiest path out of the landscape. THese bends are called meanders. If the bottom of a valley is not straight the river with follow the bottom of the valley instead of going up the sides of the valley. Also it might be to avoid big rocks
That cracking sound is the result of crepitus, which is the result of bone on bone movement or bone on ligament movement.
Bends in a river are called meanders
