Sedimentary Rocks

Sedimentary Rocks Larry Caudill Axia College of the University of Phoenix August 2, 2009 Tectonic forces smorgasbord mountains and basins and this is where it controls where the sources of worldly for deposit comes from the sites of deposition. The climate also controls the way the rocks weather and how the depositorys atomic number 18 transported. weighing machine tectonics get played a role in how sedimentary rocks are formed delinquent to the climate changes everyplace the last million years. The climate preserve determine how often piddle, ice and wind there is to guide these sediments that will form into sedimentary rocks. If the weather is mild this slows voltaic pile the process of carrying sediments and slows pop out the process of sedimentary rocks being formed. Sedimentary rocks originate from sediment that is deposited from the air, ice, wind, g ravity, or water that is flowing. The sediment disposition builds up, the lithostatic pressure so squeezes the sediment into work solids called lithification. Sediment rocks are laid down in layers called beds or strata. These new rock layers are higher up the previous(a) rock layers and they carry important information of the existences history.

Some of these rocks can carry fossils of plants and animals. This how we can classify how anile the sedimentary rock formation is by the types of fossils of the animals and plants are. on that sign are three categories that separate the different types of sediments; they a re clastic, chemical, and biogenic categorie! s. Clasts range from boulders down to clay particles that are finer than flour. clastic sediments are formed from fragmented rock and mineral deposits produced from weathering and erosion. The mixed bag of clastic sedimentary rocks is a complex classification because of many variables that are involved. This includes particle size, composition of the particles, cement, and the matrix all go to be put in consideration. There are quaternary basic...If you want to get a full essay, order it on our website: OrderCustomPaper.com
