The nucleus of the Earth is composed of iron, nickel, and iridium and has two parts - an external liquid nucleus and an internal solid nucleus. It is the innermost layer of the planet, located beneath the mantle. The internal core is made mostly of solid iron and is smaller than Pluto, while the external core is liquid and composed of iron and nickel between the mantle and internal core.
Lesson 8: Shape,Size and Structure of the earthJamaica Olazo
The Earth was formed at the same time as the other planets of the Solar System from a vast spinning disc of gas and dust.
Scientists have gathered valuable information about the Earth with the use of advance science and technology to help us understand our planet.
They have determined the size and shape of the Earth by using precise instruments and equipment.
The Earth is shaped like an Orange because it bulges at the Equator and is flat at the polar regions.
Therefore, the Earth is an Oblate Spheroid.
Geodesy – the science that studies and measures the exact size and dimensions of the Earth.

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.
