Layers of the EARTH
CRUST
5 to 25 miles thick
and up to 1,600 F
MANTLE
1,800 miles thick
and up to 8,000 F
INNER CORE
800 miles thick
and up to 13,000 F

TYPES OF ROCKS
• Igneous
• Sedimentary
• Metamorphic
IGNEOUS ROCKS
• Formed from molten
material including
volcanic lava, ash, or
bombs as well as
magma below Earth’s
surface
TYPES OF IGNEOUS ROCKS
GRANITE
BASALT
SEDIMENTARY ROCKS
• Made of layers that
have been pressed or
cemented together
• Pebbles, sand, silt, or
clay are sediments
• Shells and bones can
also be sediments
TYPES OF SEDIMENTARY
ROCKS
LIMESTONE
SHALE
COAL
METAMORPHIC ROCKS
• Rocks that are
changed by intense
heat and pressure
while inside Earth’s
surface
• Igneous, sedimentary,
and even metamorphic
rocks can be changed
into different
metamorphic rocks
TYPES OF METAMORPHIC
ROCKS
SLATE
MARBLE
ROCK CYCLE
• The rock cycle is
a never-ending
process of rocks
forming,
weathering, and
changing into
other rocks
