30. Which of the following rock types is a hydrous rock formed by chemical processes?
(1) Gypsum
(2) Shale
(3) Granite
(4) Pumice
Answer: 1
The rock type that is a hydrous rock formed by chemical processes is gypsum.
Gypsum is a chemical sedimentary rock, specifically an evaporite mineral, with the chemical formula CaSO4⋅2H2OCaSO sub 4 center dot 2 H sub 2 OCaSO4⋅2H2O (hydrated calcium sulfate). It forms when mineral-rich water, such as in shallow marine environments or salt lakes, evaporates, causing the dissolved ions to precipitate out of the solution and form a solid rock.
