Study Notes
Classification of Rocks
-
Rocks are classified based on their formation processes and composition into three main categories: Igneous, Sedimentary, and Metamorphic.
-
Igneous Rocks: Formed from the cooling and solidification of magma or lava.
- Intrusive Igneous Rocks: Solidify below the Earth's surface, characterized by large mineral crystals. Examples: Granite, Diorite, Gabbro.
- Extrusive Igneous Rocks: Formed on the surface, often glassy or vesicular. Examples: Obsidian, Pumice, Basalt.
-
Sedimentary Rocks: Formed by the deposition and cementation of mineral or organic particles.
- Clastic Sedimentary Rocks: Comprised of debris from weathered rocks. Examples: Sandstone, Siltstone.
- Chemical Sedimentary Rocks: Created from dissolved materials precipitating from solution. Examples: Rock salt, Chert.
- Organic Sedimentary Rocks: Formed from the remains of plants and animals.
-
Metamorphic Rocks: Produced from existing rocks (igneous, sedimentary, or pre-existing metamorphic rocks) undergoing heat and pressure.
- Can be classified as Foliated (with banding) and Non-Foliated (without banding). Examples: Gneiss (foliated), Marble (non-foliated).
Key Concepts and Characteristics
- Rocks are defined as naturally occurring solids made up of minerals and possibly non-mineral particles.
- Classification is done based on physical properties (color, hardness, texture) and chemical composition.
- Factors influencing rock formation include environmental conditions, presence of minerals, and biological processes.
Activities and Learning Methodology
- Engage students with practical activities, such as collecting and categorizing rock samples using observational skills.
- Encourage critical thinking through questions about grouping criteria and identifying common characteristics of rocks.
- Provide opportunities to reinforce knowledge through fill-in-the-blank exercises and classification tasks.
Summary of Key Terms
- Igneous Rock: Formed from magma/lava solidification.
- Sedimentary Rock: Created through deposition and cementation.
- Metamorphic Rock: Transformed by heat and pressure.
- Foliated: Metamorphic rock with visible layering.
- Non-Foliated: Metamorphic rock without layering.
- Clastic: Sedimentary rock formed from weathered debris.
- Chemical Sedimentary Rock: Result of material precipitation.
- Organic Sedimentary Rock: Contains biological debris.

Description
Test your knowledge on the classification of rocks, focusing on the three main types: Igneous, Sedimentary, and Metamorphic. Each category has unique characteristics and formation processes. Differentiate between intrusive and extrusive igneous rocks, as well as explore the various types of sedimentary and metamorphic rocks.
