Rock formed by the deposition of sediment, usually in a marine environment.
Rock formed by successive layers of materials, which are compacted by layers of subsequent deposits.
A rock, such as sandstone or limestone, that was once a sediment such as sand or mud, and which has not been modified substantially after burial.
A rock formed by the compaction and cementation of grains of sediment or precipitates from water (perhaps through biological action).
one of the three major types or classes of rock that form the earth's crust. Sedimentary rocks form when sediments accumulate and are then consolidated. Sedimentary rocks are formed either from pieces of pre-existing rock or are precipitated chemically. Sandstone and shale are examples of sedimentary rocks formed from pieces of other rocks and evaporites and coal are examples of precipitated sedimentary rocks.
A rock resulting from the consolidation of loose sediment (solid fragmental material that originates from the weathering of rocks) that has accumulated in layers. Sedimentary rocks represent one of the three main classes of rocks, the other two being metamorphic and igneous rocks.
A rock formed by the consolidation or cementation of sediment particles, or chemically precipitated at the depositional site.
A rock composed of materials that were carried to their present position by wind or water. Sandstone, shale, and limestone are sedimentary rocks.
Rock that forms from the accumulated products of erosion and in some cases from the compacted shells, skeletons, and other remains of dead organisms. See rock cycle. Compare igneous rock, metamorphic rock.
Rock formed by the accumulation and consolidation of sediment.
a rock formed from sediment by pressure of water or other layers of sediment
One of the three main types of rocks on earth. They form when sediments lithify, or turn into rock.
This type of rock forms either from the deposition and consolidation of fragments of preexisting rocks or through the precipitation (either biologically-mediated or strictly chemical) of minerals from solution (in water).
Sedimentary rocks are the product of the consolidation of loose sediment that has accumulated in beds. These sediments settle gradually under the weight of overlying beds and are transformed into solid sedimentary rock by cementation.
Rock formed through consolidation of sediment, forming either chemical or clastic sedimentary rocks.
rock formed from consolidated clay sediments
Rock formed by the hardening of material deposited in some process; most commonly sandstone, shale, and limestone.
Rock formed from sediments or from transported fragments natural or of geologic material deposited in water.
_Rocks formed by the accumulation osediments from weathering end erosion.
created when small particles of Earth and decomposed plant and animal life settle at the bottom of lakes, rivers and oceans and are compressed by the weight of the water until the bottom layers slowly turn into rock. Sandstone is an example of sedimentary rock. Sedimentary rock is very soft and easily flakes off, layer by layer. That is why high salinity is associated with a sedimentary ocean floor.
A rock resulting from the consolidation of loose sediment that has accumulated in layers. Some forms of sedimentary rock are formed as chemical precipitates, such as salt and some forms of limestone.
Rock. Rock formed by the accumulation and materials transported by wind, water, or ice to the site of deposition (e.g., sandstone or mudstone). Also chemically precipitated materials (e.g., limestone).
One of three classes of rock which make up the earthâ€™s outer crust; formed from the disintegration of older rocks, soils, plants, and animals. See Igneous rock and Metamorphic rock.
Formed by consolidation of deposits formed by settlement of sand, silt, and other materials.
Rock formed by the laying down of matter by seas, streams, or lakes; sediment deposited in bodies of water through geologic ages. Limestone, sandstone and shale are sedimentary rocks.
any rock formed from sediment.
A type of rock formed by chemical precipitation or by sedimentation and cementation of mineral grains transported to a site of deposition by water, wind, or ice.
Rock formed from materials deposited as sediments, in the sea, in fresh water, or on the land. The materials are transported to their site of deposition by such forces as running water, wind or moving ice. They may deposit as fragments or by precipitation from solution. Limestone and sandstone are the sedimentary rocks most used for building and gravestones.
Crushed rock and organic material layered and compacted into new rock
Rock formed when rock and mineral particles are deposited and then compressed. On Earth, sedimentary rocks often incorporate material of biological origin.
Rock formed by the accumulation of rock particles or the remains of animals or plants, or by chemical precipitation.
Rock formed from a sediment, either a precipitate or an aggregate of clastic fragments.
A rock that is the result of consolidation of sediments.
Deposited material that remains in place long enough or is covered with enough material to compact into stone; examples include shale, sandstone, breccia, and conglomerates.
Rock formed by pressure and accumulation, e.g., lakebeds changed into rock form loose sand, silt and organic materials.
A rock formed from the accumulation and consolidation of sediment, usually in layered deposits.
rock formed by the deposition and compression of mineral and rock particles, but often including material of organic origin.
a rock formed by the accumulation and cementation of mineral grains by wind, mater, or ice transportation to the site of deposition or by chemical precipitation
rock formed from the erosion, deposition and compaction of soil types (clay and silt - shale or mudstones; sand -- sandstone, arkose).
Rock formed by accumulation and cementing of loose sediment (e.g., sandstone), the deposition of chemical compounds held in solution in water (e.g., limestone), or by the accumulation of animal or plant debris (e.g., coal).
The result of sediment from erosion being broken down, decomposed, compacted, and left undisturbed until it changed into rock.
rock formed by the consolidation of loose sediment or by precipitation of crystals from an aqueous solution.
Rock that forms either by the cementing together of fragments broken off preexisting rock or by the precipitation of mineral crystals out of water solutions at or near the Earth's surface.
rock formed from deposits of sediment that have been compressed and cemented together.
A rock that formed from particles that were eroded from a previous rock, transported, deposited, and lithified. Also includes rock that accumulated as chemical precipitates.
One of the three main rock groups (along with igneous and metamorphic rocks) and is formed in three main ways - by the deposition of the weathered remains of other rocks (known as clastic sedimentary rocks); by the deposition of the results of biogenic activity; and by precipitation from solution. Sedimentary rocks include common types such as chalk, limestone, sandstone, and shale. (courtesy of wikipedia.org)
A rock formed by consolidated sediment deposited in layer.
a rock that is made up of clay, silt, sand, or cobbles which are compacted or cemented together.
Rock that began as sediments usually on the seabed.
layered mounds of rock formed mainly of material deposited by water, wind or ice.
(2XX) - Rock consisting of weathered or eroded fragments of preexisting rocks that have been cemented together as a result of chemical cementation, compression, or precipitation.
Any rock resulting from the consolidation of sediment.
rock formed when particles of eroded rock, called sediment, are pressed or cemented together
A rock composed of sediments with varying degrees of consolidation. The main sedimentary rocks include sandstones, shales, conglomerates and some limestones.
Rock formed by compression and deposition (i.e., formation of deposits) on the part of other rock and mineral particles. Sedimentary rock is one of the three major types of rock, along with igneous and metamorphic.
rocks that have been deposited as sediments in the beds of ancient seas. These sediments are laid down in distinct horizontal layers. Eventually the weight of the water compresses these sediments into fiat rock or strata.
Rock that has formed from sediment. Most fossils are found in exposed sedimentary rock.
rocks made from compressed sediments (such as sand, silt, or other deposits).
These rocks comprise fragments of rocks or living things. Sandstone is the most common sedimentary rock.
rock formed of sediment, and specifically: (1) sandstone and shale, formed of fragments of other rock transported from their sources and deposited in water; and (2) rocks formed by or from secretions of organisms, such as most limestone. Many sedimentary rocks show distinct layering, which is the result of different types of sediment being deposited in succession.
A rock resulting from the consolidation of loose sediment that has accumulated in layers (e.g., sandstone, siltstone, limestone).
rock made up of particles deposited from suspension in water. Some wind-deposited sand is consolidated into sandstone. Semi-permeable membrane

Rock formed from sediment (sand, mud, animal remains, etc) on the surface of the earth
Rock formed from the consolidation of sediments transported by water, wind or ice, or deposited by organisms
Rocks such as sandstone, and conglomerate that are composed of compacted and cemented fragments of older rocks. Some sedimentary rocks (eg limestone) are of organic or chemical origin.
A rock resulting from the consolidation of loose sediment that has accumulated in layers, or a chemical rock formed by precipitation or an organic rock consisting largely of remains of plants and animals.
Rock that results from the consolidation of layers of loose sediment made up of various kinds of organic and inorganic matter.
Rock made from the consolidation of solid fragments, as of other rocks or organic remains, or by precipitation of minerals from solution. Examples are limestone, shale and sandstone.
Limestone, shale, gypsum sandstone, etc. are sedimentary rock products used in construction or building materials. This rock is formed from sand, rock fragments, shell remains and silt compressed into a solid mass over a period of time. The absence of faults or cracks makes the strength constant throughout the entire piece.
A consolidated accumulation of rock and mineral grains and organic matter or a rock that has been formed by chemical or organic precipitation.
Sedimentary rock is rock that has formed from sediment. Most fossils are found sedimentary rock.
One of the three major types of rock, along with igneous and metamorphic rock. Sedimentary rock usually is formed by the deposition, compaction, and cementation of rock that has experienced weathering. It also may be formed as a result of chemical precipitation.
