Grain Size. Layers in sedimentary rocks are called ____ Beds. Rock salt and rock gypsum are examples of _____ sedimentary rocks. Chemical. The rock _____ is a description of how one rock may be transformed into another kind of rock through various internal and external processes.In addition to these samples you will need the following from your HOL Rock Kit: your glass plate, your streak plate, your hand lens, and; your bottle of diluted HCl. Using Table 10.1, start identifying the rocks by separating out the organic sedimentary rocks from the chemical and biological sedimentary rocks from the clastic sedimentary rocks.The only difference between chert and flint is color: flint is black or nearly black and chert tends to be white, gray, or pink and can be either plain, banded, or preserve fossil traces. This close-up of a sandstone shows a lot of quartz grains held together with a light gray calcite cement. This view is about natural size.Grain size of a sedimentary rock can be interpreted to indicate several things like the energy of the environment at the time of deposition. The higher the energy (e.g. the swifter the water), the larger the grain size that can be moved. C)compaction and cementation of rock fragments ranging in size from 0.006 to 0.2 centimeter in diameter D)compaction and cementation of rock fragments ranging in size from 0.0004 to 0.006 centimeter in diameter Which processes produced the brown siltstone layer in outcrops I and II? A)basalt B)limestone C)rock salt D)rock gypsum

EXERCISE 6.3 Identifying Sedimentary Rock Samples Examine the rock samples in your set that you classified as sedimentary rocks. Read Section 6.4 closely to remind yourself of the steps. Fill in the study sheets at the end of the chapter to identify each sample. Keep these samples and your study sheets until you have finished the chapter.A How are rock salt and gypsum formed Rock salt and Gypsum are typically formed from GEY 111 at Pikes Peak Community College. Upload to Study. Expert Help. Study Resources. ... Grain size is related to the energy of the depositional environments. The energy of transport can be by wind, water, glaciers, and gravity.Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate (CaSO4·2H2O). It is commonly found in sedimentary rock formations and is often associated with other minerals such as anhydrite, halite, and sulfur. The name “gypsum” is derived from the Greek word “gypsos,” which means “plaster” or “chalk.”. ….

ESS 210 Lab 8: Sedimentary Rock Identification 4 Organic Sedimentary Rocks . An unusual sedimentary rock is coal, a carbon-rich rock that forms when organic matter (trees and other plant matter) is buried and compressed in an oxygen-poor environment so that decomposition does not proceed. This is common in swampy settings. 3) Chemically precipitated (chemical) sedimentary rocks are those such as halite and gypsum, and some limestones, which form direct precipitation (crystallization) of the dissolved ions in the water. Clastic Sedimentary Rocks. Clastic sedimentary rocks may first be classified according to their grain size.
