Introduction Rocks are divided into three major types, viz. sedimentary, igneous, and metamorphic. The geologic reactions occurring on the Earth only cause minute alterations to the landscape in a given lifetime. The changes become evident after millions of years. Though gradual, the geologic processes can reduce a mountain to a plain. The geologic processes lead to the erosion of debris, which is then transferred to form deposits of sedimentary rock. In essence, sedimentary rocks exist at the cost of other rocks that break down through weathering and they are carried by various agents such as wind and deposited to form the rock. Sedimentary Rocks: overview Sedimentary rocks can form a string of layers, which can total up to thousands of meters in breadth. By examining these rock layers, geologists can retrieve information about the background of the Earth. The magnitude of information about the Earth’s background is tremendous. Every rock layer marks an age of geological process. Moreover, the information retrieved in line with its texture, formation, and remnants is crucial for global modification, thus revealing the nature in which the earth changes from the past, present, and future. For a geologist to study the sedimentary data properly, s/he should comprehend the contemporary sedimentary structures, their sources, mode of transit, and areas or regions where the sediments are currently settling (Stille 56). A research on the ongoing sediment formation and depositing will help one to have a clear view. The nature of the fossil recorded in the sedimentary rocks gives a glimpse on surrounding where the sediments settled and the process and timeline of how the Earth developed and transformed over time. Other than the scientific importance, sedimentary rocks also play a great role in industrial and social development. Sedimentary can be used to make various tools that are useful in accomplishing a variety of tasks. This aspect was recorded as early as in the Neolithic Age when early man made tools such as axes and arrowheads using sedimentary rocks. Some of the statues include those designed during the Renaissance and art in ancient Greek. Notably, about 90% of the known minerals are found within sedimentary rock layers. Oil, coal, cement (sand, limestone, and gravel) and fertilizer is all but a product of sedimentary rocks. Moreover, sedimentary rocks store a lot of water that people depend on for survival. Indeed, the significance of sedimentary rocks cannot be ignored. Nature of Sedimentary Rocks The constitution of sedimentary rocks is derived from mechanical and chemical breakdown of other rocks. The deposit is compressed to solid rock layers made up of organic substances, chemical remains, and pieces of minerals. One can have a good observation of sedimentary rocks by visiting the Grand Canyon in Arizona. One of the common characteristics is that they have distinct layers known as strata measuring about 100m thick with each layer having disparate and unique texture coupled with internal and external construction.
