The Structure of the Earth
(14)
The Earth is made up of four layers. Label them on to the diagram below. Once you have
done that complete the missing word exercise which follows.
The inner core is the __________ of the Earth. It is made of solid iron and nickel. This is the
_______________ part of the Earth with temperatures of around _________°C. The outer
core is made up of liquid iron and nickel. The _______________ is the
largest section of the Earth and is made up of ___________________ rock (plastic properties).
These partially melted rocks are called magma. Temperatures here are around 5,000°C.
The crust is the _______________ layer of the Earth and is made up of solid rock. The crust
is the outer layer of the Earth. The Earth's crust is broken up into pieces called
______________, which move or 'float' upon the mantle. Heat rises and falls in the mantle
creating currents. These are called _____________ currents. These currents cause the
Earth's plates to move. The plates move very ______________ (around one or two millimetres
a year). The movement of the Earth's plates is known as ___________________________ .
