Rocks study
| Term | Definition |
|---|---|
| How do Metamorphic rocks form | Changed by extreme heat and pressure deep inside the earth |
| What does the word Metamorphic mean | Change of form |
| How do Metamorphic rocks start of as | These rocks start out as igneous, sedimentary, or even or even other metamorphic rocks ( called the parent rock) |
| What are the two primary ways that rocks undergo a change | Contact Metamorphic and Regional Metamorphic |
| What are the rock textures of Metamorphic rocks | Foliated and Non foliated |
| What is foliated | The extreme pressure causes the minerals to line up in flat layers or bands |
| What is non-foliated | The minerals are squeeze together, but they do not form layers or bands |
| What is an example of foliated | Gneiss and Slate |
| What is example of non-foliated | Marble and Quartzite |
| Every metamorphic rock comes from a | Preexisting rock |
| How do Sedimentary rocks form | Through specific step by step processes that takes thousands or millions of years |
| Weathering | Rocks are broken down into smaller pieces ( sediment) by wind water or ice |
| Erosion | These sediments are moved from one place to another |
| Decomposing | The sediments are dropped or settle in a new location often at the bottom of a lake or ocean |
| Compaction | Overtime layers of sediment buildup the weight of a top layers squishes the bottom layers together |
| Cementation | Minerals in the water act like glue binding the sediments together into solid rock |
| Sedimentary goes through the process of what | Weathering erosion deposition compaction, and cementation (WEDCC) |
| What are the tree types of texture, sedimentary rocks | Clastic chemical organic |
| Clastic | Made from Brocken pieces (clasts) of other rocks that have been compacted and cemented together |
| Chemical | Formed when water evaporates and leaves behind dissolved minerals that crystallize |
| Organic | Formed from the accumulated remains of once living things like plants or shells |
| Examples of clastic | Sandstone, shale, and conglomerate |
| Examples of chemical | Rock salt (Halite) , Gypsum |
| Examples of Organic | Coal, Fossilferous limestone |
| What are the types of textures of igneous rocks | Intrusive and Extrusive |
| Intrusive | Forms inside the Earth from slowly cooling magma and has large visible crystals |
| Extrusive | Forms outside on the surface from fast cooling lava and has small or no visible crystals |
