Definition
| rocks formed by weathering and erosion of rocks into smaller pieces or sediment. They are deposited , compacted and cemented togeter by pressure, into layers. |

Term
|
Definition
rocks that have "morphed“, or changed into another kind of rock.
These rocks were once igneous or sedimentary rocks. Heat and pressure squeeze the sedimentary or igneous rock and change it into. |

Definition
| these processes change the structure and texture of rock. This is what changes sedimentary rock into metamorphic rock. |

Term
|
Definition
| (from the Greek word for fire) rocks that form from hot molten rock (magma).The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. |
|

Definition
| The hot liquid that forms when rock partially or completely melts. |
|

Term
|
Definition
igneous rock that forms when magma is trapped deep inside the Earth. It cools very slowly over many thousands or millions of years until it solidifies.
Intrusive igneous rock can be pushed to the surface by plate movement. |
|

Term
|
Definition
igneous rock that is formed when magma exits and cools outside of, or very near the Earth's surface.
These are the rocks that form at erupting volcanoes. |
