Layers of the Earth
ROCK CYCLE
Imagine…
If you journeyed to the
center of the Earth, what
do you think you would see
along the way? Draw an
illustration of your journey.
Parts of an apple
Peel = crust
Fruit = mantle
Outer core = core
Inner core = seed
Layers of the Earth
• Skin of the peach is
the crust
• Meat of the peach is
the mantle
• Pit of the peach is the
core
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
OUTER CORE
1,400 miles thick
and up to 11,000 F

Mantle
Largest layer
of Earth
Made of hot,
solid rock
Core
Made of oxygen,
silicon,
magnesium, and
iron
When it melts, it
becomes magma

--How are the earth’s
layers similar to an
egg?
• Shell=crust
• Egg white=mantle
• Yolk=core
