kivilajimuokkauksia
Kivilajimuokkauksia refers to the processes by which the physical and chemical properties of rocks are altered. These alterations can occur over geological timescales through various natural mechanisms. Weathering, both physical and chemical, is a primary driver of rock modification. Physical weathering involves the disintegration of rocks into smaller pieces without changing their chemical composition. This can happen through processes like freeze-thaw cycles, thermal expansion and contraction, and abrasion. Chemical weathering, on the other hand, involves the decomposition of rocks through chemical reactions. Common examples include dissolution, oxidation, and hydrolysis, which transform minerals into new compounds.
Other significant processes contributing to kivilajimuokkauksia include metamorphism, which is the transformation of existing rock types
