How Sedimentary Processes Create Mineral Resources
Chemical and mechanical. Chemical weathering changes the chemical makeup of minerals and hence breaks them apart. For example, when sugar is stirred into water, the sugar dissolves (the sugar crystal breaks apart into the molecules that compose it; it is no longer a crystalline solid). This is a type of chemical weathering. ... Access Doc
