Students will review:
In this chapter, you'll learn the answers to questions including:
- What are the different kinds and unique features of sediment?
- How do chemical sedimentary and detrital rocks differ?
- What occurs during the lithification of sediments?
- How do scientists determine the origins of sedimentary rocks?
1. Sediment: Definition, Types & Features
Sediment is fragments of past living or non-living materials that have been broken down. There are three types of sediments that can form sedimentary rocks. Learn about clastic, biogenic and chemical sediments and the rocks they form in this lesson.
2. Detrital & Chemical Sedimentary Rocks: Definition & Differences
Detrital or clastic sedimentary rocks are composed of rock fragments. They are different than chemical sedimentary rocks, which are composed of mineral crystals. Learn how these sedimentary rocks differ in their formation and composition.
3. Lithification of Sediments: Definition & Processes
Lithification is the process that turns loose, unconsolidated sediment into solid sedimentary rock. Learn about the three ways lithification is accomplished, including compaction, cementation and recrystallization, in this lesson.
4. Determining the Origin of a Sedimentary Rock
Sedimentary rocks contain features that indicate the kind of environment from which they originated. Learn about sedimentary structures, such as graded bedding, cross-bedding, ripple marks and mud cracks, and how they provide clues to the rocks origin in this lesson.
5. Conglomerate: Definition, Uses & Facts
Learn about conglomerate, a sedimentary rock formed from large, rounded rock fragments in a matrix of fine grained sediments. While not as widely useful as other rocks, conglomerate does have some applications in the construction industry.
