    • Weathering Module Introduction

      The major types of chemical weathering are dissolution, acid hydrolysis, and oxidation. Dissolution. Dissolution is a process whereby a mineral passes completely into a solution, like salt dissolving in water. Some minerals dissolve directly in water and the ions leached/flushed away.

      Chemical weathering occurs when rock dissolves or the composition of a rock changes through chemical processes. The simplest chemical process is called . dissolution. or the dissolving of a rock or mineral. Slightly acidic rain reacting with rock will slowly dissolve rock and release the chemical components of the rock into solution. A second ...

      Thus, dissolution in the natural environment is generally much slower. It is important to understand that this activity is a model of chemical and physical weathering and has some limitations. Make sure that students understand the relative timeframes for geologic change as they relate to weathering of rock.

      In addition, chemical weathering is generally enhanced in wet environments. The physical weathering of rocks increases the rate of chemical weathering by increasing the surface area on which chemical reactions occur. This is analogous to the more rapid dissolution of granulated sugar in a cup of coffee relative to a single large rock sugar crystal.
