The Rock Cycle
All rocks are related to each other and may be transformed from one kind to another. The rock cycle describes the relationships between the 3 major types of rock:
Igneous Rocks - Formed from the cooling of molten rock (magma).
Sedimentary Rocks - Formed from layers of sediment as the pressure of overlying layers compacts the sediment into rock. Sometimes, a cementing agent, dissolved minerals such as silica or carbonates, helps bind the sediment particles together.
Metamorphic Rocks - Formed from other rocks that are exposed to intense heat and pressure and thus change their physical and/or chemical form.

Rock Cycle processes
IGNEOUS
Melting – hot temperatures deep inside the Earth melt rocks, forming magma
Cooling and hardening – magma that rises form deep inside the Earth cools as it reaches the surface, hardening into rock. Magma also cools beneath the surface.
SEDIMENTARY
Weathering and erosion – weathering breaks apart existing rocks forming sediment. Erosion moves sediment to new locations.
Compacting and cementing – pressure compacts sediments together. Water between particles evaporates, leaving minerals that cement sediments.
METAMORPHIC
Heat and pressure – heat and pressure inside the Earth melt and squeeze minerals in rocks. This changes the minerals themselves or their grain sizes.

Igneous Rock
soils.uga.edu geology.com learner.org
Formed from cooled molten rock (called magma beneath the surface and lava above the surface)
Inside the Earth
Can be heated under pressure to become metamorphic rock
Can be melted again to form new magma
Above the ground
Can be weathered, eroded, compacted and cemented to become sedimentary rock
