• Minerals

• Sediments

• Convection

• Compaction

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

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 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.

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

• Sediments

• Weathering

• Deposition

• Compaction

A prosses by which new seafloor is formed from the magma rising from Earths diverging ocean plates.
