To in chemical weathering as organic and several

Tobegin with, weather is defined as the breaking down of rock material. In lightof this, this paper explains the differences between physical and chemicalweather and definition of inorganic and organic.Physicalor mechanical weathering is the disintegration of rocks into smaller piecesthat involve no chemical composition. The physical break up of these rocksproduces crystallization of salt in the rocks, the water freezes, as pressureis released, thermal expansion and contraction takes place. Additionally, therocks are broken apart in layers that are parallel to the earth’s surface butas the rocks are exposed, it expands and results in exfoliation..

 Consequently, the exposure of these rocksthrough the process of mechanical weathering makes it more vulnerable tofurther chemical and physical weathering. However, the shattered fragments are easierto transport compared to chemical weathering.  Chemical weathering is quite different fromphysical weathering because it is the breakdown of rocks as a result ofchemical reactions (CaCo3+CO2+H2O—> Ca2++ 2HCO3). That is to say, it entailsthe decomposition and transformation of primary minerals into secondaryminerals and the minerals being change are mostly clay. In addition, water isconsidered to be the major operator in chemical weathering as organic andseveral ironic compounds such as Silica, K, Na, Mg, Ca, Cl, CO3, SO4 dissolvein water.

Compared to physical weathering, there is acidic reactions, organic activities,oxidation, dissolution, hydration and hydrolysis during chemical weathering.The major difference is thatphysical weathering relates to landform that is to say the physical cold andvery dry environment while chemical weathering involves decomposition/transformationof minerals or rocks due to the exposure of the wet and hot environment.Organic and inorganic are theprimary disciplines or basis of chemistry. Organic are compounds in chemistry thatcontains carbon and hydrogen  or C-Hbonds while inorganic are compounds or molecules that do not contain carbon.Examples of organic molecules in living organisms are fats, sugars, protein,nucleic acids etc.
