• Minerals

• Sediments

• Convection

• Compaction

A process during which one type or rock changes into another type of rock through geologic prosses.

(a)  

the process by which heat is transferred directly from one material to another material

• Convection

• Minerals

• Seafloor Spreading

• Weathering

A circulating flow of air or water resulting from temperature differences.

(a)  

A rock that formed when magma or lava cooled and crystallized on or below earths surface.

• Igneous Rock

• Sedimentary Rock

• Metamorphic Rock

• Monerals

​ (a)   occurs when sediments are deposited on the ground or sink to the bottom of a river, lake, or ocean. ​ (b)   occurs as increased pressure forces the grains of sediments together.

• Deposition
• Compaction

Rock that forms over time as sediments become compacted and cemented together.

• Sedimentary Rock

• Igneous Rock

• Metamorphic Rock

• Sediments

Rock formed from another rock that has been exposed over a long time to heat and pressure and has changed into a different rock.

(a)  

tiny pieces of broken rocks that have been weathered by rain, wind, snow, plant roots, or other environmental agents.

• Sediments

• Weathering

• Deposition
