Определение sedimentary rocks в Английский Язык Английский Язык словарь
rocks, which have been deposited in layers, often by water, and consist of material worn away from pre-existing rock
Formed from the lithification (cementation) of sediment Sedimentary rocks may be composed of mineral or rock particles (clasts) to form sandstones, claystones or sediments of biological origin to form limestone and peat, or of chemical precipitation to form evaporites
Rocks formed from consolidation of loose sediments such as clay, silt, sand, and gravel
rocks formed by the accumulation of fragments, or the precipitation of dissolved material, that result from the weathering of pre-existing rocks
Rocks formed from the layering and cementing of sediment (In Illinois, common sedimentary rocks are limestone/dolomite, shale, and sandstone )
A rock resulting from the consolidation of loose sediment that has accumulated in layers
Rocks formed on the earth's surface or sea floor from small particles or dissolved substances from other rocks
rocks formed by the settling of particles in water or air These accumulations result in layers and bedding
a rock formed of fragments transported from their source, usually by water The sediments are usually laid down in layers Sandstone and limestone, the two major rocks found at Mammoth Cave, are both sedimentary
Secondary rocks formed from material derived from other rocks and laid down under water, e g , limestone, shale and sandstone
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 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
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
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 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 made up of particles deposited from suspension in water The chief kinds of sedimentary rock are conglomerate, formed from gravel; sandstone, formed from sand; shale, formed from clay; and limestone, formed from soft masses of calcium carbonate There are many intermediate types Some wind-deposited sand is consolidated into sandstone
Rocks formed by the deposition, alteration and/or compression, and lithification of weathered rock debris, chemical precipitates, or organic sediments Also see clastic vs non-clastic sedimentary rocks
Rocks formed from material derived generally by erosion of other rocks and laid down by a chemical or mechanical process i e , limestone, shale and sandstone
