Igneous, Sedimentary & Metamorphic Rocks with Rock Cycle
| Term | Definition |
|---|---|
| Rock | A solid inorganic material that is usually made of two or more minerals. |
| Igneous, Sedimentary & Metamorphic | The three types of rocks. |
| Igneous | When melted rock cools or hardens on or under Earth's surface. |
| Intrusive | Type of igneous rock that forms under Earth's surface. |
| Extrusive | Type of igneous rock that forms on top of the Earth's surface. |
| Sedimentary | Rocks formed of pieces of other rocks, plant and animal matter or dissolved minerals. |
| Detrital or Clastic | A type of sedimentary rock where grains from minerals or broken rocks have been compressed. |
| Chemical | Type of sedimentary rock where mineral-rich water evaporates and from other chemical processes. |
| Organic | Type of sedimentary rock where dead plants and animals have been compressed. |
| Crystal Size | The main difference between intrusive and extrusive igneous rocks. |
| Small Crystal Siize | Found in extrusive igneous rocks. |
| Large Crystal Size | Found in intrusive igneous rocks. |
| Granite | Example of a intrusive igneous rock. |
| Basalt, Pumice & Obsidian | Examples of a extrusive igneous rocks. |
| Limestone & Coal | Examples of Organic Sedimentary Rocks. |
| Conglomerant | Example of a Detrital or Clastic Sedimentary Rock. |
| Halite | Example of a Chemical Sedimentary Rock. |
| Metamorphic Rock | Form when existing rocks are heated or squeezed changing them physically and chemically. |
| Foliated | Type of Metamorphic Rock where minerals form lines over time, great heat and pressure. |
| Nonfoliated | Type of metamorphic rock where minerals appear uniform a rock that has been changed under great heat and pressure. |
| Gneiss, Schist, Slate | Examples of Foliated Metamorphic Rock |
| Soapstone, Quartzite, Marble | Examples of Non-foliated Metamorphic Rock |
| The Rock Cycle | A model that shows a rock's continuing journey from one rock type to another. |
| Weathering & Erosion | The process of wind, water or ice breaking down large rocks into small pieces. |
| Melting | The process of sediments or other rocks being melted into Magma. |
| Large Amount of Heat, Pressure and Time | The process of sedimentary or igneous rocks becoming a metamorphic rock. |
| Small Amount of Heat and Pressure on Sediment | The process of forming sedimentary rocks. |
