Sedimentary rocks. Sedimentary rocks are made when sand, mud and pebbles get laid down in layers. Over time, these layers are squashed under more and more layers. Eventually, the layers are lithified â turned to rock. Sedimentary rocks can be formed in deserts, lakes, rivers and seas.
Sedimentary rocks are formed on the earth's surface by the deposition and lithification of sediment. They comprise the weathered rind of the lithosphere. Because sediment is deposited incrementally over a surface, sedimentary rocks are layered and, unless deformed by some tectonic event, horizontal.. Detrital sedimentary rocks: These rocks are composed of mineral grains and/or rock fragments transported and deposited by some geologic agent. Detrital rocks are typically composed of mineral grains derived from silicate rocks.
