Deformational structures are geological features that form as a result of stress and strain within the Earth's crust, leading to the folding, faulting, or fracturing of rocks. These structures provide valuable information about the tectonic processes that have shaped the Earth's crust over time. Examples include folds, faults, joints, and foliations.
Brittle deformation results in structures like fractures, fault gouge, and breccia. These structures form when rocks break or fracture due to stress without significant plastic deformation. They are commonly found in highly stressed and brittle rocks near the Earth's surface.
Analogous structures are structures that have the same function but different structures. They have evolved independently in different organisms to perform similar roles in response to similar environmental pressures. An example is the wings of birds and bats, which have different structures but both serve the same function of flight.
Structures in project environments can include organizational structures (hierarchical, matrix, flat), communication structures (formal and informal channels), governance structures (roles and responsibilities), and work breakdown structures (dividing project tasks into smaller components). These structures help to define how the project team operates and communicates to achieve project goals.
man-made structures were made by humans, but natural structures made itself.
Structures that have similar structure and function but different evolutionary origins are called analogous structures. These structures have evolved independently in different species to serve the same purpose due to environmental pressures or adaptations. An example is the wings of birds and insects, which are used for flight but have different evolutionary origins.

The force which changes the dimension of the object such as length, volume or which changes the shape is known as deforming force
Deformational metamorphism is a type of metamorphism that occurs in response to tectonic stresses, like folding, faulting, or shearing. It can lead to the development of foliation or other textural features within the rocks. The changes are typically accompanied by recrystallization, but the mineralogical composition may remain relatively unchanged.
Homologous structures.
structures which are similiar
They are purposeless structures
Structures that share a common evolutionary origin are called homologous structures. These structures may have different functions in different species, but they share a common ancestry.

The unitary structures refers to the structures of a political organization whereby governing power is concentrated at the center. The currency and presidency are examples of the unitary structures.
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.
Structural geology is usually applied in areas where it is necessary to understand the in-situ stress state and deformational history (both rheological meaning ductile deformation such as folding and tectonic or brittle deformations such as faulting and jointing) of a rockmass.
