Sedimentary rocks are one of three main rock types, alongside igneous and metamorphic rocks. Sedimentary rocks are formed over million of years, as sediments (broken remains of other rocks) compact on the Earth's surface, under seas, lakes, and oceans.

Clastic Sedimentary Rocks . The most common set of sedimentary rocks consists of the granular materials that occur in sediment. Sediment mostly consists of surface minerals — quartz and clays — that are made by the physical breakdown and chemical alteration of rocks. These are carried away by water or the wind and laid down …Flint is a hard, tough chemical or biochemical sedimentary rock that breaks with a conchoidal fracture. It is a form of microcrystalline quartz that is typically called "chert" by geologists. Flint often forms as nodules in sedimentary rocks such as chalk and marine limestones. The nodules can be dispersed randomly throughout the rock unit but ...Clastic Sedimentary Rocks. How Clastic Sedimentary Rocks are Formed: Pre‑existing rock undergoes chemical and mechanical weathering by roots, acid rainwater, gravity, wind, and water. The broken particles are carried through water or air until they settle out in a lower area when the current wasn't fast enough to carry the particles.Detrital Sedimentary Rocks. Detrital sedimentary rocks form from detritus, the rock and mineral fragments that are transported by gravity, water, ice, or wind. Detrital sediments are classified by grain size.

Marl is an unconsolidated sedimentary rock consisting of clay and lime. Chalk is a soft, white, powdery limestone consisting mainly of fossil shells of foraminifers. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.Fossils are primarily found in sedimentary rocks because these rocks form at low temperatures and pressures. Igneous rocks form at temperatures and pressures that are high enough to destroy any organic remains.

Igneous rock is formed through the cooling and solidification of magma or lava.
