weathered products of preexisting rocks that
have been transported, deposited, compacted,
and cemented.
3. Metamorphic rock is formed by the alteration of
pre-existing rock deep within Earth (but still in the
solid state) by heat, pressure, and/or chemically
active fluids.
Metamorphic rocks
C. Materials from Earth
1. Magma is molten material inside Earth
2. Lava is magma that reaches the surface.

F. Energy That Drives the Rock Cycle
1 heat from the Earth’s interior forming both
igneous rock and metamorphic rock.
2 Weathering is powered by energy from the
sun.
3 External processes produce sedimentary
rocks.
