29 Οκτ 2024 · erosion, removal of surface material from Earth’s crust, primarily soil and rock debris, and the transportation of the eroded materials by natural agencies (such as water or wind) from the point of removal.
4 Ιαν 2018 · We present a unifying definition and advance a conceptual framework for (a) examining the effects of bioerosion on natural systems and human infrastructure and (b) identifying and predicting the impacts of anthropogenic factors (e.g. climate change, eutrophication) on bioerosion.
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement.
1 Ιαν 2013 · The term bioerosion was coined by Neumann (1966) for hard substrate destruction by organisms (Greek, “bios” life; Latin “erodere” erode). It was originally restricted to calcareous rocks but is now being used for biogenic removal of all types of rocks, engineering works, and mineral and organic skeletons.
We present a unifying definition and advance a conceptual framework for (a) examining the effects of bioerosion on natural systems and human infrastructure and (b) identifying and predicting the impacts of anthropogenic factors (e.g. climate change, eutrophica- tion) on bioerosion.
The term bioerosion has been used to refer to many different types and scales of processes in the literature and generally can be thought of as the weathering and/or removal of material by organic agency (see for example, Spencer, 1992).
Bioerosion refers to the removal of rock by direct organic activity. It includes the work of boring organisms which drill holes into rocks by mechanical or chemical methods (Figure 3(e)) and grazing organisms that scrape off the surface of rocks as they feed on the roots of epi- and endolithic microflora.
