Rock Cycle
Basic defintions
Weathering- the disintegration or decomposition of rock
Erosion- the destruction of rocks by the force of moving agents
Transportation- movement of rock
Deposition- settlement of rock debris
Uplift- forces that push rocks upwards from deep within the Earth
Melting- transformation of solid rock into a liquid melt
Energy
External energy
Energy that powers erosion, weathering, transportation and deposition
1) GRAVITY- generated by the mass of Earth
2) SOLAR ENERGY- from the sun
Internal energy
powers the geological processes that occur from below the ground
1) RADIOACTIVE DECAY- of unstable elements with too many neutrons
2) PRESSURE
3) RESIDUAL HEAT- heat left over from the early molten phase, trapped within the core
CASE STUDY- High Force
limestone dolerite limestone
Sedimentary- formed by the accumulation of weathered and eroded debris
Metamorphic- formed when heat or pressure change pre-existing rocks into new ones
Igneous- formed by the crystallisation of molten magma
conduction- movement of heat from warm objects to colder objects by sensible heat transfer
convection- the movement of heat within a circulating deformable material
heat radiation- process by which thermal energy is transferred in the form of electromagnetic waves
