1. Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks
In this lesson, we will discuss the three main types of rocks and how they are formed. The lesson also gives an introduction into how matter locked in rocks can be cycled through the earth.
2. Types of Rocks: The Three Major Rock Groups
Did you know that lava is molten rock that reaches the earth's surface? Furthermore, did you know that rocks exist in three general forms: igneous, sedimentary and metamorphic? This lesson describes these rock types and examples of each.
3. Bowen's Reaction Series: Crystallization Process & Magmatic Differentiation
Bowen's reaction series and magmatic differentiation are two ways of explaining how igneous rocks form. Learn about the continuous and discontinuous series of the Bowen's reaction series and how magmatic differentiation works in this video lesson.
4. Classification of Igneous Rocks: Textures and Composition
Igneous rocks can be classified by their texture and composition. Learn how texture is influenced by the cooling rate of magma and how different mineral compositions lead to different igneous rock classifications in this video lesson.
5. 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.
6. 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.
7. Metamorphism of Rocks: Definition, Process & Influencing Factors
Exposure to intense heat and pressure can result in the metamorphism of previously formed rocks. Learn about the factors that influence metamorphism and the metamorphic processes: recrystallization, neometamorphism and metasomatism in this lesson.
8. Classification of Metamorphic Rocks: Texture & Parent
Metamorphic rocks are classified by their texture, which is either foliated or non-foliated, and according to their parent rock. Learn about the different textures and parent rocks of metamorphic rocks.
