The Three Types of Rocks
What is a Metamorphic Rock?
"A metamorphic rock is a result of a transformation of a pre-existing rock. The original rock is subjected to very high heat and pressure, which cause obvious physical and/or chemical changes. Examples of theserock types include marble, slate, gneiss, schist." http://www.onegeology.org/extra/kids/metamorphic.htmlWhat is a Sedimentary Rock?
"Sedimentary rocks are formed by sediment that is deposited over time, usually as layers at the bottom of lakes and oceans." http://www.sciencekids.co.nz/sciencefacts/earth/sedimentaryrocks.html
What is a Igneous Rock?
"Igneous rock is formed through the cooling and solidification of magma or lava." https://en.wikipedia.org/wiki/Igneous_rock
----------------------------------------------
Vocabulary For The Rock Cycle
Erosion: The process by which wind, water, ice, or gravity transports soil and sediment from one location to another
Deposition: The process in which material is laid down
Compaction: The process by which the porosity of a given form of sediment is decreased as a result of its mineral grains being squeezed together by the weight of overlaying sediment of by mechanical means.
Cementation: The binding together of particles or other things by cement.
Heat: To cause something to be warm or hot
Pressure: The action of pressing or pushing against something
Melting: Changing its temperature, pressure, and water content. This creates the liquid form of a rock.
Cooling: For something to become less hot.
Sediment: Matter that settles to the bottom of a liquid; dregs.
Magma: A very hot layer of liquid inside the Earth's crust that can form Igneous rocks from the liquid cooling.
Examples of Metamorphic Rocks...
- anthracite
- quartzite
- marble
- slate
- granulite
- gneiss
- schist
----------------------------------------------
Examples of Sedimentary Rocks...
- breccia
- conglomerate
- sandstone
- siltstone
- shale
(The rocks listed above are mainly formed from mechanical weathering debris.)
