Answer: Sedimentary rocks contain the entire history of life on earth that is available to us, and much of the history of the Earth itself. All of this information will help us determine how we got where we are today.
Grain size is more important for determining the classification of clastic sedimentary rocks, such as sandstone or shale. Composition is more important for determining the classification of chemical sedimentary rocks, such as limestone or rock salt. Layering is more important for identifying the structure of sedimentary rocks, such as bedding in sandstone or shale.
ORGANIC SEDIMENTARY ROCK`s : Is a type of sedimentary rock because sedimentary rock has three types of sedimentary rock called clastic , chemical , and organic sedimentary rock so yes ORGANIC SEDIMENTARY ROCK is a type of sedimentary rock..........................................
Clastic sedimentary rock.
rocky
compaction and cementation
Clasts are individual pieces of rock or mineral fragments that make up a sedimentary rock. They can vary in size and shape, ranging from tiny grains to large boulders, and are important in determining the characteristics and composition of the sedimentary rock.
a mushroom rock is not a sedimentary rock.
It is then sedimentary rock.
Sediments, Pressure, And Heat
Mechanically formed sedimentary rock , Chemically formed sedimentary rock and Organically formed sedimentary rock.
Sedimentary rock can be formed from lithified sediments.
Nothing. Scientists have reached consensus that there is absolutely nothing important or special about sedimentary rock. Sedimentary rocks are barely even rocks. Some scientists are pushing to have sedimentary rocks declassified as rocks, and reclassified as extraneous matter.
