- Enjoy our sedimentary rock facts for kids. Find interesting information and a range of examples that help explain what sedimentary rocks are and what makes them different from other kinds of rocks. Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans. This sediment can include minerals, small pieces of plants and other organic matter. The sediment is compressed over a long period of time before consolidating into solid layers of rock.

Sedimentary Rocks Lesson #13 Sedimentary rocks are formed in three ways from these different sized sediments. A sedimentary rock is a layered rock that is formed from the compaction, cementation, and the recrystallization of sediments.Compaction is the squeezing together of layers of sediment due to the great weight of overlying layers of rock.on-clastic sedimentary rocks form from the precipitation (Precipitation is the separating of a solid from a solution) of minerals from ocean water or from the breakdown of the shells and bones of sea creatures. Sea animals such as coral produce calcium carbonate solutions that harden to form rock.

Sedimentary Rocks: Definition, Types & Examples A distinguishing property of all sedimentary rocks, such as the limestone in the upper half of the picture and the shale in the lower half, is that they form in beds, or layers, which are the result of how the sediment was deposited over time.

Sedimentary rocks Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped.

Pictures of Sedimentary Rocks Shale is a clastic sedimentary rock that is made up of clay-size (less then 1/256 millimeter in diameter) weathering debris. It typically breaks into thin flat pieces. The specimen shown above is about two inches (five centimeters) across.

- Sedimentary rocks are rock particles and mineral grains (sediments) deposited in a fluid (water or air) and subsequently transformed to rocks (lithified). They typically occur in layers (strata) separated by bedding planes and differences in composition.edimentary rocks are rock particles and mineral grains (sediments) deposited in a fluid (water or air) and subsequently transformed to rocks (lithified).

Sedimentary rock Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth 's surface and within bodies of water.hemical sedimentary rock forms when mineral constituents in solution become supersaturated and inorganically precipitate. Common chemical sedimentary rocks include oolitic limestone and rocks composed of evaporite minerals such as halite (rock salt), sylvite, barite and gypsum.

Pictures of Sedimentary Rocks 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. It often forms as nodules in sedimentary rocks such as chalk and marine limestones.

- Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth 's surface and within bodies of water.lastic sedimentary rocks are composed of silicate minerals and rock fragments that were transported by moving fluids (as bed load, suspended load, or by sediment gravity flows) and were deposited when these fluids came to rest.

Sedimentary rock Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in four main ways: by the deposition of the weathered remains of other rocks (known as 'clastic' sedimentary rocks); by the accumulation and the consolidation of sediments; by the deposition of the results of biogenic activity; and by precipitation from solution.

Detrital & Chemical Sedimentary Rocks: Definition & Differences Detrital or clastic sedimentary rocks are composed of rock fragments. They are different than chemical sedimentary rocks, which are composed of mineral crystals. Learn how these sedimentary rocks differ in their formation and composition.et's review…. Detrital sedimentary rocks, also called clastic sedimentary rocks, are composed of rock fragments that have been weathered from pre-existing rocks. They are the most common rocks on the surface of the earth. Detrital sedimentary rocks are mainly classified by the size of their grain.

Sedimentary rock Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth 's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle and accumulate or minerals to precipitate from a solution.

- Sedimentary rock is rock that is formed in layers by the depositing and pressing of sediments on top of each other. Sediments are any loose material that gets broken away and carried: pieces of rocks, pebbles, sand, clay, silt, boulders, dead organisms, animals, plants, shells, insects. . . .hen, over a long time, layers and layers of sediments get deposited on top of each other, the weight of the top layers presses down on the bottom layers, forming them into rock called sedimentary rock. The oldest layers are on the bottom, and the youngest layers are on the top.

- Sedimentary rocks are rocks composed of sediment. Sediment is deposited in a number of environments of deposition, by both moving air and moving water. Sedimentary rock identification is primarily based on composition.

Examples of clastic sedimentary rocks are shale, sandstone, and conglomerate.lastic sediments are sediments that have particles or pieces of rock (clasts) in them. The clasts can be of igneous, metamorphic or sedimentary rock.

- Sandstone is a category of rock made from sediment (a sedimentary rock). The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock.
