Ch 10: Sedimentary Rocks: A Deeper Look

About This Chapter

Watch video lessons and learn about the different kinds of sedimentary rock and how fossils can give us clues about its origins. These lessons are just a portion of our earth sciences learning materials.

Sedimentary Rocks: A Deeper Look - Chapter Summary and Learning Objectives

Sedimentary rocks are any rocks that are created by the accumulation of sediment, which could come from biological debris, material that precipitates out of various solutions, or mechanical processes. Some common sedimentary rocks include coal, flint, dolomite, limestone and sandstone. In this chapter, video instructors will describe lithification and other processes that explain the origins of sedimentary rocks. You'll learn about the vocabulary associated with sedimentary rocks. At the end of this chapter, you should be able to:

  • Name the three different types of sedimentary rocks and describe their characteristics
  • Identify the features of sedimentary rocks, including strata and fossils
  • Explain what fossils and other features can tell the observer about the formation of the sedimentary layer
  • Differentiate between the three major processes of lithification

Sediment: Defintion, Types, and FeaturesDefine sediment. Identify three types of sediment: clastic, chemical, and biogenic. Discuss some features, including fossils and layering (strata).
Classification of Sedimentary Rocks: Detrital and ChemicalDefine and differentiate between detrital (clastic) and chemical sedimentary rocks.
Lithification of Sediments: Definition and Processes Define lithification. Explain the three processes that lead to lithification of sediments (compaction, cementation and recrystallization).
Origination of Sedimentary Rock Explain how features like ripple marks, cracks and fossils can indicate the kind of environment in which a sedimentary rock originated.
