Definitions for "SEDIMENTARY ROCKS"
Rock is generally classified in one of three categories: a. Sedimentary; b. Igneous; c. Metamorphic.
Rocks formed from material, including debris of organic origin, deposited as sediment by water, wind or ice and then consolidated by pressure.
Rocks formed as the result of accumulation of sediment in water or air. The sediment can be particular, as in sand grains or clay, or a chemical or biochemical precipitate as in diatomaceous earth.
