Some reference stations, however, exhibit a larger amplification in ground motion, probably due to the weathering condition of surface rock or near-site path effects characterized by a kappa value much smaller than 0.025 used in the model.
The cleaning method is meant to be used on stone material placed in outdoor environment where natural weathering of the surface is occurring.
(33) Dissolution and evaporation appear to have been more important than biodegradation in the weathering of the surface slick.
A legacy indicator tool (LegIT) has been developed as one possible solution, focussed on measuring the weathering of stone surfaces into the far future.
The particle flux is high enough to cause darkening or space weathering of their surfaces on an astronomically rapid timescale of 100,000 years.
Poor upland weather conditions, a lack of surface water (due to the permeable limestone), thin soils and bare rock (where there is limestone pavement) mean that crops cannot be grown.
The weathering of Ida's surface revealed another detail about its composition: the reflection spectra of freshly exposed parts of the surface resembled that of OC meteorites, but the older regions matched the spectra of S-type asteroids.
Weathering of the carved surface varies from moderate to severe.
Nanoscale imaging of the same interface suggested accelerated weathering of the mineral surface due to biological interactions, as indicated by a contrast in grain texture between a site on the mineral surface previously in contact with a fungal hypha versus an adjacent smooth site with no evidence of hypha interaction (Fig. 2c).
Giganotosaurus lacks this vascular groove completely, although weathering of the bone surface may have removed this feature.
However, on an airless body such as Itokawa, weathering of material on surfaces cannot be the product of movement of any kind of fluid, particularly on the surface of bodies.
