Transcript The rock cycle A3.1x

The rock cycle
• Topics: Mineral and Rock processes; Characteristics of
rocks and minerals
• NCSCOS 3.04 Describe the processes which form and
the uses of earth materials: rock cycle, minerals,
characteristics of rocks, economic use of rocks and
minerals, value of gems and precious metals, common
gems, minerals, precious metals and rocks found in NC.
• ES 6.E.2.3 Explain how the formation of soil is related
to the present rock type and the environment in which
it develops.
6.E.2.3 explained: Forces deep inside Earth and at the
surface produce a slow cycle that builds, destroys, and
changes rocks and crust. Plate movements start the
rock cycle by helping to form magma, the source of
igneous rocks. Plate movements also cause faulting,
folding and other motions of the crust that help form
sedimentary and metamorphic rock. Minerals form as
hot magma cools inside the crust, or as lava harden on
the surface. When liquids cool to a solid state, they
form crystals. When elements and compounds that
are dissolved in water leave a solution, crystallization
of minerals occurs.
