Extrusion - the emission of magma onto Earths surface where it forms a lava flow
Weathering - the breakdown of rock in situ
Erosion - the removal of weathered material, usually by the physical action of transported fragments
Deposition - the laying down of sediment that occurs when a transporting agent loses energy
Burial - occurs when sefiment is covered by younger layers of sediment accumulating on top of it
Diagenesis - defines all processes that take place in sediments at low temp and pressure at or near the Earths surface
Recrystallisation - the solid state process that changes minerals into new crystalline metamorphic minerals
Metamorphism - the changing of rocks in the Earths crust by heat and/or pressure and/or volatile content. It is isochemical and occurs in solid state
Partial melting - the invomplete melting of rock in the lower crust or upper mantle
Magma accumulation - magma collecting within a chamber
Crystallisation - occurs during the cooling of magma or lava so that solid mineral crystals form
Intrusion - an igneous rock formed below the Earths surface. Magma can be forced into…
