one of the major groups of rock that makes up the crust of the Earth; formed by the deposition of either the weathered remains of other rocks, the results of biological activity, or precipitation from solution
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
Rock formed at or near the Earth's surface by the accumulation and lithification of fragments of preexisting rocks or by precipitation from solution at normal surface temperatures. Sedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata. They are the most common rocks exposed on the Earth's surface but are only a minor constituent of the entire crust. Their defining characteristic is that they are formed in layers. Each layer has features that reflect the conditions during deposition, the nature of the source material (and, often, the organisms present), and the means of transport. See also sedimentary facies
Rocks in beds composed of particles of other rocks, organic matter, or materials deposited from solution in water Examples: limestone, sandstone, shale; most fossils are found in sedimentary rock
A rock made from the consolidation of solid fragments, as of other rocks or organic remains, or by precipitation of minerals from solution
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 formed from the consolidation of sediments transported by water, wind or ice, or deposited by organisms
One of the three main types of rocks on earth They form when sediments lithify, or turn into rock
Sedimentary rock played a primary role in the formation of the Adirondacks, and is one of the three great rock classes that encompass all rocks Sedimentary rocks are formed at or near the earth's surface by the accumulation of particles in size varying from submicroscopic to boulder size Sediments accumulate, often to a thickness measured in miles The weight of the upper beds exerts enormous pressure on the lower beds causing heating, compaction, and cementing of the beds into rock layers Over time and in this manner, mud becomes mudstone and then shale, sand is consolidated into sandstone, etc Sedimentary rocks are easy to recognize due to their layered structure
Rock formed from the weathered products of preexisting rocks that have been transported by water, wind, or glaciers Sandstone is a type of sedimentary rock
These rocks comprise fragments of rocks or living things Sandstone is the most common sedimentary rock
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
Rock formed by pressure and accumulation, e g , lakebeds changed into rock form loose sand, silt and organic materials
Rock formed by the cementing and hardening of many layers of fine material, usually deposited by water, e g , sandstone, shale
rock formed from particles generally weathered and eroded from pre-existing rock material but also from the deposition of shells and other organic detritus (e g , carbonate rocks) or the precipitation of salts from solution
rock formed by the deposition and compression of mineral and rock particles, but often including material of organic origin
