    Types of Chemical Weathering Reactions Hydrolysis - H + or OH-replaces an ion in the mineral. Example: Leaching - ions are removed by dissolution into water. In the example above we say that the K + ion was leached. Oxidation - Since free oxygen (O 2) is more common near the Earth's surface, it may react with minerals to change the oxidation state of an ion.

    What physical processes contribute to the weathering of rock and why might you expect mafic igneous rocks to weather at a faster rate than felsic igneous rocks? Weathering is the physical disintegration and chemical decomposition of rocks into soil, loose clasts, dissolved chemical components (ions), and solid chemical residues. ...
