INTERNAL
CORE
EXTERNAL COREMANTLE
CORTEX
5. PARTS DEFINITION
- Internal core: The internal core is made of iron and
is smaller than Pluton.
- External core: The outer core of the Earth is liquid.
It is composed of iron and nickel and is between the
mantle and the internal core.
- Mantle: The mantle of the Earth is between the
external core and the cortex. The mantle is 33 km
deep.
-Cortex: It is the rocky part of the Earth.The most
abundant elements of this layer are silicon, oxygen,
aluminum and magnesium.
