Ans: Silica rocks are mostly formed because of the chemical precipitation and hence deposition because of exogenous processes. Thus, as it fulfills the definition of sedimentary rocks, silica is a type of sedimentary rock. Mainly those sedimentary rocks that are rich in silica are categorized as silica rocks or siliceous rocks.
