- 3 major rock types: Igneous, Metamorphic, and Sedimentary
- 75% of rocks at earth's surface: Sedimentary Rock
- cementation: when the solution of water and dissolved minerals move through open spaces between sediments and cement the sediments together
- chemical: form when minerals are precipitated from a solution or left behind when a solution evaporates
- compaction: pressure upon layers of built up small sediments on lower layers causing lower layers to stick together and form solid rock
- congeneration: when both electrical and thermal energy produced by burning waste-coal used by the same plant (to run the plant)
- detrital: sedimentary rocks made from the broken fragments of other rocks that are compacted and cemented together
- erosion: the movement of weathered material
- examples of chemical rocks: limestone and rock salt
- examples of detrital rocks: larger: conglomerate and breccia smaller: sandstone and shale
- examples of organic rocks: fossil rich limestone, coquina, and coal
- Foliated Rocks: texture of rocks resulting from mineral grains flattening and lining up in parallel bands
- hydrate: mix with water
- Igneous Rocks: rocks formed by the cooling of molten rock (either magma or lava)
- Metamorphic Rock: rocks that have changed due to temperature and pressure
- most common rock below earth's surface: Igneous Rock
- Non-Foliated Rocks: texture of rocks where the mineral grains grow, change, and rearrange but do not form bands
- organic: rocks formed from remains of once living things
- Rocks: a mixture of minerals, mineraloids, glass, and organic matter
- Sedimentary Rock: form when 1.)sediments become pressed or cemented together 2.)sediments precipitate out of a solution
- sedimentary rocks are classified by:: compostion and the way they form
- sediments: loose material such as rock fragments, mineral grains, and bits of plant and animal remains moved by wind, water, ice, gravity, or dissolve on water
- types of sedimentary rock: detrital, chemical, and organic
- waste coal: a poor quality coal that is a by-product of coal mining
- weathering: process that breaks rocks into smaller pieces
