Ch 11: Sedimentary & Metamorphic Rocks
About This Chapter
Sedimentary & Metamorphic Rocks - Chapter Summary
Check out these engaging and informative earth science lessons to learn basic information about sedimentary and metamorphic rocks. As you follow along with our expert instructors, you'll closely examine topics like metamorphism, lithification, rocks origins, rock classifications and much more. When you're finished with each lesson, try the accompanying self-assessment quiz to reinforce your understanding of important rock vocabulary and concepts. The chapter is accessible at any time of day or night, and you can use any computer or mobile device to study. By the end of the chapter, you should be able to:
- Recognize the different types of sediment
- Differentiate between chemical and detrital sedimentary rocks
- Explain lithification processes
- Determine a sedimentary rock's origin
- Describe the process of rock metamorphism
- Classify metamorphic rocks
- Evaluate the differences between regional and contact metamorphism
1. Sediment: Definition, Types & Features
There are three main types of sediment, or past materials that have been broken down. Explore the features of clastic sediment, biogenic sediment, and chemical sediment, and gain an understanding of the different types of sedimentary rocks and fossils.
2. Detrital & Chemical Sedimentary Rocks: Definition & Differences
Detrital rocks are composed of rock fragments, or clasts, and chemical rocks form through a chemical process. Explore the features in formation of these two sedimentary rocks, different kinds of sedimentary rocks, and methods of categorization.
3. Lithification of Sediments: Definition & Processes
Lithification is a process where solid rock is formed from loose, differentiated sediment. Learn how to define lithification and explore the three processes of lithification, which include compaction, cementation, and recrystalization.
4. Determining the Origin of a Sedimentary Rock
Sedimentary rocks are rocks formed from the accumulation of rock particles, minerals, and organic matters on the Earth's surface. Explore the origin of sedimentary rocks through different methods such as stratification, graded bedding, cross-bedding, ripple marks, and mud cracks.
5. Metamorphism of Rocks: Definition, Process & Influencing Factors
Rocks that have changed after being exposed to heat and/or pressure are known as metamorphic rocks. This lesson defines this process and explores it by looking at influencing factors, including recrystallization, neometamorphism, and metasomatism.
6. Classification of Metamorphic Rocks: Texture & Parent
The classification of metamorphic rocks is based on the parent rock, which is protolithic, and their texture. Learn about foliated vs. non-foliated rocks, regional and contact metamorphism, and the protoliths of foliated rocks.
7. Contact Metamorphism Vs. Regional Metamorphism: Definition & Differences
Contact metamorphism is where minerals and texture are changed as rock encounters lava, whereas regional metamorphism is where this process occurs over large areas. Understand the definitions and learn the differences and features involved in these metamorphic processes.
