Question

how is hydration different from solution in chemical weathering?​

Answer 1

Answer:

Although simple solution, hydrolysis, and oxidation are the most important chemical weathering processes, under certain conditions several other processes can facilitate chemical weathering of minerals. Hydration is the process whereby water molecules are added to a mineral to form a new mineral.

Explanation:

Hydration is the process whereby water molecules are added to a mineral to form a new mineral. Common examples of hydration are the addition of water to hematite to form goethite, or to anhydrite to form gypsum. Hydration is accompanied by volume changes that may lead to physical disruption of rocks. Under some conditions, hydrated minerals may lose their water, a process called dehydration, and be converted to the anhydrous forms, with accompanying decrease in mineral volume. Dehydration is relatively uncommon in the weathering environment because some water is generally present.
