| 3 Types of Sedimentary Rocks |
|
Definition
| detrital, organic, and chemical |
|
|
Term
|
Definition
•made of individual particles, skeletal remains or broken fragments of previously existing rocks
•particles are cemented together by other minerals
•rocks that do not have broken fragments are usually crystalline in appearance |
|
|
Term
|
Definition
| formed directly or indirectly from once-living materials |
|
|
Term
|
Definition
•Formed when a sea or lake dries up
Large amounts of minerals are left behind when the water evaporates
•Evaporation and Precipition of minerals are the reasons they form. In other words, minerals come out of the water to form crystals. |

Term
|
Definition
| usually crystalline looking and no evidence can be seen that it was formed from broken pieces of other rock |
|
|
Term
|
Definition
| a process in which sediments are cemented or “glued” together by minerals dissolved in water to form sedimentary rocks |
|
|
Term
|
Definition
| process by which layers of sediments are pressed together to form sedimentary rocks |
|
|
Term
| evaporation and precipitation |
|
Definition
the minerals in seawater turn into
crystals or rock because the water evaporates |

Term
| Features in identifying sedimentary rocks |
|
Definition
1. have visible layers
2. may contain fossils
3. may have ripple marks
4. may have mud cracks |

Term
|
Definition
| rocks that have been changed from an existing type of rock into a new type; most are formed deep beneath the earth’s surface |
|
|
Term
|
Definition
| occurs when rocks are heated by contact with magma or lava |
|
|
Term
|
Definition
| occurs over large areas when rocks buried deep beneath the earth’s surface are changed by increases in temperature and pressure . Mountain building is the most common example. Most metamorphic rocks are of this type. |
|
|
Term
|
Definition
| a type of metamorphic rock texture having mineral crystals arranged in parallel layers, or bands |
|
|
Term
|
Definition
| a type of metamorphic rock texture that does not have bands of crystals and does not break into layers |
