Sedimentary rocks are, as the name suggests, formed from the buildup of sediment. This means they form over time on the surface of the Earth, unlike other types of rock, such as igneous or metamorphic, which are created deep within the Earth under great pressure or heat. Sedimentary rocks are mainly caused by gradual but constant natural ...

5.3.1 Lithification and Diagenesis. Lithification turns loose sediment grains, created by weathering and transported by erosion, into clastic sedimentary rock via three interconnected steps. Deposition happens when friction and gravity overcome the forces driving sediment transport, allowing sediment to accumulate.

Limestone. Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.Sediments are transformed into sedimentary rock through cementation. This is a process that precipitates minerals in the spaces between sediment particles.The Rock Most Likely to Contain Fossils. Fossils, the preserved remains of animal and plant life, are mostly found embedded in sedimentary rocks. Of the sedimentary rocks, most fossils occur in shale, limestone and sandstone. Earth contains three types of rocks: metamorphic, igneous and sedimentary. With rare exceptions, …Following are the two types of igneous rock: Intrusive igneous rock: These rocks crystallise below the earth’s surface resulting in large crystals as the cooling takes place slowly.
