Sediment: Definition, Types & Features

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.

Detrital & Chemical Sedimentary Rocks: Definition & Differences

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.

Lithification of Sediments: Definition & Processes

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.

Determining the Origin of a Sedimentary Rock

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.

Metamorphism of Rocks: Definition, Process & Influencing Factors

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.

Classification of Metamorphic Rocks: Texture & Parent

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.

Contact Metamorphism Vs. Regional Metamorphism: Definition & Differences

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.
