Rock+Cycle

=media type="custom" key="7479765"= Rocks are always in a state of change. The human lifespan does not allow us to notice. All rocks start as one rock material and through the processes of __Cooling & Crystallizing__, __Weathering__, __Heat & Pressure__, and __Melting__, change into new rock materials. media type="youtube" key="pm6cCg_Do6k" height="353" width="425"

 * = ==Molten==

Rock
|| Heat from the center of the Earth changes solid rock to molten rock. Molten rock is lighter that solid rock so rises up the the surface of the Earth. ||= ==Melting== ||
 * = ==Igneous==

Rock
|| Crystals are clearly seen due to molten rock cooling slowly. ||= ==Cooling==

Crystallizing
|| Bits and Pieces of rocks broken by wave action of water which is an example of Weathering. ||= ==Weathering== ||
 * = ==Sediments== || [[image:beach sand.jpg width="286" height="178" align="center"]]
 * = ==Sedimentary==

Rock
|| Layers are a visual characteristic when sediments are compacted and cemented together. ||= ==Compacting==

Cementing
||
 * = ==Metamorphic==

Rock
|| Curved and bent layer patterns are produced through heat and pressure placed on an already existing rock. ||= ==Heat==
