Sedimentary rocks were created through multiple instances of applied pressure and natural cementation. They're rarely shiny since they did not make contact with concentrated sources of heat. Sedimentary rocks are generally coarse-grained and not shiny.

Clastic sedimentary rock is composed of particles of previously existing rock. The most common example of this would be sandstone, a rock composed of cemented particles of sand where the texture can be seen and felt. The particles in clastic rock need not be sorted or homogenous however. Conglomerate and breccia are also clastic sedimentary rock where different cemented rock fragments are easily visible and may vary greatly in size and lithography. Stratification is also visible in many clastic sedimentary rocks. The stratification (layering) is due to cyclical, event based, or origin based deposition of sediments.
Organic sedimentary rocks like coal and some limestones are partially or wholly derived from the life processes of organisms and that fact may be reflected in an abundance of fossils appearing in the rock. Fossils are not found in igneous rock or metamorphic rock except in very rare instances due to unusual circumstances. Normally, the discovery of a fossil is a good indication that the rock is sedimentary.
Sedimentary rocks couldbe, or exhibit:
- Sedimentary layers from cyclical deposition.
- The presence of fossil organisms.
- Be derived from organic processes (like coal).
- Be more porous and less dense than other rock types.
- Reaction to dilute acids.
- Formed of particles of other rock fragments.
- Fine grained.
- Created by evaporation of saturated solutions.

Name three sedimentary rocks used for decorative landscape or building materials?
Sedimentary rocks are often used for decorative landscapes and as building materials. Three of these include limestone, sandstone and dolomite.
Why are sedimentary rocks not used for construction purpose?
the gap bettween the molecules of sedimentary rocks where too large that is force of attraction bettween molecules is very low,so that it is weak as we can break it with our hands
What is the composition of a sedimentary rock?
Small solid materials that come from pieces of rocks and living organisms
What criterion is used to divide rocks into three groups?
The classification is based on the processes that formed the rock.
How have humands used sedimentary rock?
== == There are several different ways that people use sedimentary rocks. The chalk used in classrooms around the world is a type of sedimentary rock. Limestone is a sedimentary rock that is used in concrete, building stones, antacids, soil conditioner, and steel making. Coal is another sedimentary rock which is used to produce heat and electricity. Shale is used to make brick. Sandstone is used in construction and glass production.
Which sedimentary rocks used to construct monuments?
Sand stones are a form of sedimentary rocks and are widely used in construction of monuments.
Does industry have to do anything with sedimentary rocks?
I don't think industry have anything to do with sedimentary rocks because industry is used for goods.
Is masomry stone a sedimentary rock?
Sedimentary rocks (such as sandstone and limestone), igneous rocks (such as granite and basalt), and metamorphic rocks (such as marble) are all used in masonry.
What rock is used in soil mixes?
sedimentary rocks
Fossils that can be used to establish relative dates are most likely to be found in?
sedimentary rocks.
Is the sedimentary rock strong?
That depends on the rock. Some sedimentary rocks are used as construction material, or as raw material for different kinds of industries. Older sedimentary rocks have a scientific value as well, as ages of fossils can be determined by studying them.
What is a poem for sedimentary rocks?

Is sedimentary rocks extrusive or intrusive?
Neither. Intrusive and extreusive are terms used to differnetiate different types of igneous rock. They do not apply to sedimentary rocks.
What criterion is used to subdivide the detrital sedimentary rocks?
nothing.
What is the main type of energy used to help converts rocks in metamorphic rocks in the rock cycle?
Sedimentary rocks
Name three sedimentary rocks used for decorative landscape or building materials?
Sedimentary rocks are often used for decorative landscapes and as building materials. Three of these include limestone, sandstone and dolomite.
Do sedimentary rocks have parent rocks?
In a sense they do, but not in the geologic sense that a metamorphic rock does. Most sedimentary rocks are formed from particles of other rocks which could be a mixture of all three types (sedimentary, igneous, metamorphic). Therefore they would have multiple parents, so the term "parent rock" is not used. The term most used is "source rock'.
