Hole identified nine natural processes resulting in soil disturbance, including the movements of animals and plants (known as bioturbation, and including burrowing, root growth and treefalls); freezing and thawing; movement under gravity (including earthflow and rockslides); swelling and shrinking ...
Disturbance (archaeology), any change to an archaeological site due to events after the site was laid down Disturbance (ecology), a temporary change in average environmental conditions that causes a pronounced change in an ecosystem
The Permian through Jurassic stratigraphy of the Colorado Plateau area of southeastern Utah is a great example of Original Horizontality and the Law of Superposition, two important ideas used in relative dating.
Historical ecology involves an understanding of multiple fields of study such as archaeology and cultural history as well as ecological processes, species diversity, natural variability, and the impact of human-mediated disturbances. Having a broad understanding of landscapes allows historical ecology to be applied to various disciplines.

[10] The act of looting serves as a disservice to both stolen objects and the sites themselves, as objects lose their historical context and sites lose record of even having that object in ...
Taphonomy is the study of how organisms decay and become fossilized or preserved in the paleontological record. The term taphonomy (from Greek táphos, τάφος 'burial' and nomos, νόμος 'law') was introduced to paleontology in 1940 [1] by Soviet scientist Ivan Efremov to describe the study of the transition of remains, parts, or products of organisms from the biosphere to the lithosphere.
