Other curbment agencys sedimentary materials nuclear number 18 transported be streams, glaciers, lakes, oceans, and wind. everywhere time layering occurs in a fulfill called lithification. Geologists can study these layers to discover how quondam(prenominal) generations lived.

For instance, graded beds argon created at the fuck of a river or stream.

The three different categories of sedimentary rocks are classified ad by the size, shape, and angular shape of the material. Gravel, sand, back upy entangle, and expectant mud are ex amples of clastic sediments.

Over time and compressing gravel be commences a conglomerate, sand becomes sandstone, silt becomes siltstone, and clayey mud becomes shale or mudstone. Breccia is a clastic sedimentary rock. Volcaniclastic sediments are also clastic sedi ments but differ because they come from volc! anoes. Sediments from volcanoes are unique because as they come up from the background there igneous rocks and when they flow from a volcano they are sedimentary. As this heated material flows from the volcano there called pyroclasts (Murck, Skinner, & Mackenzie, 2008). chemic sentiment is dissolved matter that has made its way to the sea or the lakes. Plants and animals alter the chemical balance of the water scheme they live in....If you want to get a full essay, govern it on our website: BestEssayCheap.com
