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. Clastic Sedimentary Rocks: Definition, Types & Examples
Clastic sedimentary rocks are the geologic record of places like streams, deserts, and flood plains. This lesson covers the wide variety of clastic sedimentary rocks and what they tell us about geologic history.
6. What is Limestone? - Properties, Types & Uses
In this lesson, learn about limestone, a calcium carbonate-rich chemical sedimentary rock. There are several varieties, including fossil containing rocks, which can be found all over the world. It has numerous uses, particularly as a building material.
