Web9 nov. 2015 · Classes of sedimentary rocks. Geologists divide sedimentary rocks into four major classes, based on their mode of origin. (1) Clastic sedimentary rock consists of cemented-together clasts, solid fragments and grains broken off of preexisting rocks (the word comes from the Greek klastos, meaning broken); (2) biochemical sedimentary … WebA) Smaller particles settle faster than larger particles. B) As a current slows, the largest particles start to settle. C) Faster currents carry larger particles than slower currents. D) …

WebName:Krithik Ashokkumar Date:12/16/2024 Per:3 Sedimentary Rock Lab Sedimentary rocks form through the process of lithification, which has five steps: weathering, erosion, deposition, compaction and cementation. Sedimentary rocks are classified by their formation: clastic, chemical, and organic. WebClastic Sedimentary Rocks • Composed of cemented mineral grains/rock fragments • Created by: – Weathering: breaking rocks into smaller pieces – Erosion: removing grains from parent rock – Transportation: dispersed by gravity, wind, water, and ice – Deposition: settling out of the transporting fluid – Lithification: transforming into solid rock WebAs an extension of diagenesis, a process that occurs during lithification ( Chapter 5 ), burial metamorphism can cause clay minerals, such as smectite, in shales to change to another clay mineral illite. Or it can cause quartz sandstone to metamorphose into the quartzite such the Big Cottonwood Formation in the Wasatch Range of Utah. daft ballina rent
