
Rock Cycle-Continuous
changing and
remaking of rocks
 Any of the 3 types of
rocks can be
transformed into
another type of rock by
natural Earth processes

Igneous rocks are formed from the
crystallization of magma
 Granite-Makes up Earth’s continental crust
 Basalt-Makes up Earth’s oceanic crust

Sedimentary rocks are rocks
that were formed through
the deposition and
solidification of sediments
 Sediments-Pieces of solid
material
 Sandstone, Limestone
Metamorphic rocks form when rocks are changed
by heat and/or pressure
 The heat allows atoms to rearrange themselves

 Gneiss, Marble

Igneous Rock
Formation:
 Sedimentary and
Metamorphic rocks can
be melted down, and
then cooled to form
igneous rocks

Sedimentary Rock Formation:
 Igneous or Metamorphic rocks can become
weathered and eroded and then lithified
(cemented together) into sedimentary rocks

Metamorphic Rock Formation:
 Igneous and Sedimentary Rocks can be
transformed by heat or pressure to form
metamorphic rocks
