ROCKS AND THEIR CLASSIFICATION SEDIMENTARY ROCK

Sedimentary rocks are rocks that are extended up to 75% of the earth’s surface. This rock is mainly formed by the process of cementation. This is the process involved in ions that are carried out from groundwater that is precipitated from the crystalline material that can be found in between sedimentary grains. Sedimentary rocks are the rocks that follow the structure called bedding. This rock deposit in the large structure, the study of sedimentary rock and its rock strata provide us with information about earth history that can give the brief knowledge of the natural resources that include substances like coal, fossil fuel and so on.

Main body

How sedimentary rocks are formed?

Sedimentary rocks are mainly formed by the weathering preexisting rocks that are mainly the deposition of the weathering product. Weathering is the process that includes various physical disintegration with chemical decomposition that occurs from rainfall. These rocks are formed by the gradual and constant changes in the environment. These rocks are also formed by the process called erosion, precipitation, or natural weathering which also include dissolution. These rocks are mainly formed by the accumulation of sediments that include iron ore, rock salt, and limestone. These rocks are also formed from the accumulation of the dead remains of plants and animals.  when the rock masses got eroded with time or washed away by natural phenomena after all these processes take place within a year this material settled down by process of sedimentation this sedimentation process . By this process sedimentation rock formed by pressure height limestone, mudstone, and sandstone hardens the sediment and transfers it into the rock. This process takes year after year to form sediment this process includes.  Deposited material layer after layer from the new sheet.  There are mainly three types of sedimentary rock Clastic sedimentary rock are mainly formed by deposition as a result of mechanical weathering. They also include rocks like sandstone, shale, and many more.  Another type is chemical sedimentary rocks that form when water components are evaporated and left the dissolved minerals behind this rock include rock salt, iron ore, and others.  And the last one is the organic sedimentary rock that mainly includes an accumulation of animal products such as shells and bones. The examples of these rocks are coal, limestone.

Properties of sedimentary rock

Sedimentary rocks are the rocks that are largely found on the earth’s surface These rocks are non-crystalline in types or nature these rocks also contain round grain in nature. they are soft; they have mainly layers that are formed by the deposition.  They are generally non-shining in nature the main properties of sedimentary rocks are porosity sedimentary rocks have the highest porosity. Clay is the most porous element and least permeable element and also because the grain does not fit together well. Sedimentation and the sediment control prosperity that include sorting, grain shape, and overburden stress. Permeability is another property of the sedimentary rock that allows water and other liquid to pass through the rocks. Gravel among sedimentary rock is the most permeable.  Rounding is another property of sedimentary rocks: clastic sediment grain is round in nature. Roundness makes the rock smooth due to the absorption of sedimentary particles. Another property is Grain structure. It is the most important thing that decides the rock formation along with the quality of the rocks. Grains are the sediment and minerals. that are present inside the rock. Another property is sorting which is involved in the process of distribution in grain size from sediment rock or unconsolidated deposits or sedimentary rocks; these are some properties that can be observed in sedimentary rock.

Application of sedimentary rock

 In this portion, it will mainly discuss the different and various uses of sedimentary rock that help in functioning with different features such that in building stone is also used in construction purposes like sand and gravel that also used to make concrete, asphalt sedimentary rocks also help in getting valuable resources. The other uses of sedimentary rocks are sandstone and limestone in the construction process. The limestone is used to make cement and it is also used in cement factories. Rock gypsum is used to make plaster.  Sedimentary rock is also used in natural gas, coal and is also applied in various energy resources processes that mainly come from this rock. Shale  is also used for making roads and also used in making pottery, brick and many other substances. Sedimentary rocks are also valuable in fossils because they do not destroy the fossils that remain. Sedimentary rocks are used in various construction projects because they are light eight soft and easy to cut. These are the different applications of sedimentary rock in different fields. 

Conclusion 

In this article, it has been discussed about the classification of sedimentary rock and its application. Here in this assignment, it is also discussed the process of forming sedimentary rock. That mainly includes the types, properties along characteristics of this rock, by analyzing these we can understand the quality and the process of how it works and the impact of weathering on this rock. Here it is also discussed about the different applications of sedimentary rocks by their differences from with different characteristics and also discussed the quality of its process of chemical decomposition. This is all mentioned in the above work of the assignment.
