largest part
made up of - silicon, oxygen, aluminium
ductile - like playdough feeling
700km deep

Question 4

inner core

Answer 4

iron, nickel
solid
very hot

Question 5

convection currents

Answer 5

The plates are constantly moving around due to a process called CONVECTION CURRENTS.
The hot liquid mantle creates friction against the underneath of the plates, which then either pushes the plate or drags it backwards depending on the direction of the convection beneath.

Convection currents result in the shifting of the tectonic plates, known as continental drift.
