Sep 23, 2023 · Sedimentary rock, rock formed at or near Earth’s surface by the accumulation and lithification of sediment or by the precipitation from solution at normal surface temperatures. Sedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust.

Marble is metamorphosed limestone (a chemical sedimentary rock). Slate was once used as the backing of chalkboards. Any type of rock can be metamorphosed, including metamorphic rocks.
