The Rock CycleForces deep inside Earth and at the surface produce a slow cycle that builds, destroys and changes the rocks in the crust.

Rock Cycle: is a series of processes on Earth’s surface and in the crust and mantle that slowly changes rocks from one kind to another.

Facts About The Rock Cycle(1) Plate Tectonics and Rock Cycle interlocked/united together.

(2) Any rock can make any other rock:

A Sedimentary Rock can produce a Igneous Rock, another Sedimentary Rock or a Metamorphic Rock.

An Igneous Rock can produce another Igneous Rock, a Sedimentary Rock or Metamorphic Rock.

A Metamorphic Rock can produce an Igneous Rock, a Sedimentary Rock or another Metamorphic Rock.

(3) Sediments first before Sedimentary Rocks can be made.

(4) Magma first before Igneous Rocks can be made.

Facts About The Rock Cycle

Rock Processes:(1) Magma: Melting

Igneous Rocks: Solidification

(2) Sediments: Weathering, Erosion

Sedimentary Rocks: Deposition, Burial, Compaction, Cementation

(3) Metamorphic Rock: heat & pressure (no melting)

A Cycle of Many PathwaysIgneous Rock: cooling & solidification of magma/lava.

Plate Tectonics: uplift

Sedimentary Rock: weathering, erosion (sediments), deposition, burial/accumulation, compaction & cementation (lithification).

Plate Tectonics: plate collision, mountain-building, subduction

Metamorphic Rock: heat & pressure (and chemical reaction) at great depth of any rock.

Plate Tectonics: melting subducted plate, rising magma plume, volcanoes form at surface.

The Rock Cycle & Plate TectonicsIgneous Rocks: Plate movements start the rock cycle by helping to form magma, the source of igneous rocks. Where plates move apart and where ocean/continental or continental/continental plates come together, magma forms and cools forming igneous rocks.

The Rock Cycle & Plate TectonicsSedimentary & Metamorphic Rocks: The collision of continental plates can result in uplift and mountain-building. The mountains eventually are worn away leading to the formation of sedimentary rocks. In addition, this collision can push rocks down deep into the mantle where heat and pressure changes the rocks into metamorphic rocks.
