What is a Rock Cycle?

• Recycling the Earths material

Lithification
Sediment

• Process by which unconsolidated rock-forming
  materials are converted into consolidated
  or coherent state.

Sedimentary Rock

Metamorphism
Sedimentary Rock

• A process whereby rocks undergo
  physical or chemical changes or both to
  achieve equilibrium with conditions other
  than those under which they were
  originally formed

Metamorphic Rock

Fusion
Metamorphic Rock

• Change of a substance from the
  solid to the liquid state, usually by
  the application of heat.

Magma

Crystallization
Magma

• Process through which crystals
  separate from fluid, viscous, or
  dispersed state.

Weathering, Erosion, and Transfer

• WeatheringResponse of materials once in
  equilibrium within earth's crust to new
  conditions at or near contact with water,
  air, or living matter.

• Erosion Movement of material from one place to
  another on Earth's surface. Agents of
  movement include gravity, water, ice, and
  wind.

Human Impact on Rock Cycle

• Rock cycle is an Earth interior system.
• It is rarely influenced by human.
  Basically the rock cycle is not affected by human
  impact.
