Weathering can be either a chemical or a physical process. The action of water causes physical weathering of rock. Which example
Scilla [17]

Frost wedging is a type of physical weathering of rock.

Explanation:

Physical or mechanical weathering affects the rock structurally but does not change the chemical composition. Mechanical forces will rub, break or shatter the rock surfaces. Wedging, abrasion, exfoliation are different types of physical weathering.

Water is one of the main sources which alter the structure of the rocks physically.

Frost wedging occurring due to flow of freezing water over the rocks. This frozen water enters the rock through the cracks and crevices on the rock surface,  and will expand inside and makes the rocks to crack further and breaks it apart.

What are the biological structures
vesna_86 [32]

Answer:Biological structures are able to adapt their growth to external mechanical stimuli and impacts. For example, when plants are under external loads, such as wind force and self-weight, the overloaded zones are reinforced by local growth acceleration and the unloaded zones stop growing or even shrink. Such phenomena are recorded in the annual rings of trees. Through his observation of the stems of spruce, K. Metzger, a German forester and author, realized that the final goal of the adaptive growth exhibited by biological structures over time is to achieve uniform stress distribution within them. He published his discovery in 1893.12 A team of scientists at Karlsruhe Research Centre adopted Metzger's observations and developed them to one single design rule: the axiom of uniform stress. The methods derived from this rule are simple and brutally successful like nature itself. An excellent account of the uniform-stress axiom and the optimization methods derived from it is given by Claus Mattheck in his book ‘Design in Nature’.13 The present study utilizes one of these methods, stress-induced material transformation (SMT), to optimize the cavity shape of dental restorations.
