Cellulose is more durable than lignin and becomes the main composition on wood surface after weathering, which contributes to the hydroxyl concentration on the surface. When water contacts the weathered wood, a larger amount of interactions between the hydroxyl groups and water would undoubtedly occur. Therefore, weathering definitely increase the wettability of the wood.

Climate is often viewed as the aggregate of all of the elements of weather, with quantitative definitions being purely physical. However, because of couplings of carbon dioxide and many other atmospheric species to both physical climate and to the biosphere, the stability of the climate system depends in principle on the nature of feedbacks involving the biosphere. For example, the notion that sulfate particles originating from the oxidation of dimethylsulfide emitted by marine phytoplankton can affect the albedo (reflectivity) of clouds (Charlson et ai, 1987). At this point these feedbacks are mostly unidentified, and poorly quantified. 

A specific example of this would be the weathering of K-feldspar and the formation of kao-linite (see Table 8-1 for mineral definitions), a layer-silicate clay ... 

Most weathering reactions consume protons and produce alkalinity (Reactions (5.2) and (5.3), and Table 5.4). Here we briefly review the definitions and illustrate the value of the alkalinity-acidity concept in the context of the weathering reactions. 

Whether the plume is being sought in air or water, weather conditions will definitely affect the formation of the plumes. Appropriate scheduling holds promise for more success. 

In addition to a better understanding of the reaction of sulfide with ferric oxides and its role in pyrite formation, a more exact definition of the term reactive iron is critical. Does reactive iron mean a different iron oxide fraction for bacterial dissolution (e.g., weathering products such as goethite or hematite) than for reaction with sulfide (e.g., reoxidized lepidocrocite) In other words, is there a predigestion of ferric oxides by bacteria that allows a subsequent rapid interaction of sulfide with ferric oxides ... 

Iron ores occur in igneous, mctamorphic or sedimentary rocks, or as weathering products of various primary iron-bearing materials- For convenience of analysis, iron ores are grouped into (I) igneous tires. 121 contact ores. i3i hydrothermal ores. (4) sedimentary ores, with several suhclassihcaiions of the latter ores. Brief definitions follow ...
