What is the rock cycleForces deep inside the Earth and at the
surface produce a slow cycle that builds, destroys, and changes the rocks in the crustRock Cycle a series of processes that occur on the surface, in the crust, and mantle, that slowly change rock from one kind to anotherex Granite >weathering >compaction> cementation
= sandstone
Feb 108:29 PM
One pathway through the rock cycleThere are many pathways by which rocks move through
the rock cyclemagma cooled>granite mountain>uplifting>weathering/erosions> granite is broken down to sandstone >deposition on the ocean floor> compaction & cementation>more pressure from the building up layers changes thesandstone> quartzite

The rock cycle and plate tectonicsChanges in the rock cycle are closely related to plate
tectonicsEarth's lithosphere is made up of huge platesPlates move slowly over the Earth because of
convection currentsThe plates carry continents and oceansThey drive the rock cycle by helping form magma
= igneous rock
Feb 108:47 PM
Oceanic plates move apart, magma moves up and fills in the space with new igneous rock
When oceanic crust is subducted beneath the continental plate, magma form and rises as volcanoes

Continental plate and continental plate collision pushes rock deep down where it melts and form igneous rock
Continental plate and continental plate collision may be strong eneough to push up mountains, that leads to weathering and erosion = sedimentary rock
Feb 108:51 PM
Continental plate and continental plate collision can push rocks deep beneath the surface. Heat and pressure change the rock = metamorphic rock

Conservation of materials in the rock cycleconstructive and destructive forces build up and destroy land masses
material is not lost or gainedsize of the Earth doesn't change'recycle'

Lesson 6 The Rock Cycle
Forces deep inside the Earth and at the surface produce a slow cycle that builds, destroys and changes the rocks in the crust
