STARTER: What does this picture show? Copy: The Earth is broken up like a jigsaw. These pieces are called plates.
COPY: The plates are part of the crust which float on the mantle. This is made of molten (melted) rock called magma. COPY: The inner core is made of solid iron and nickel (metal) and is 5400°C. This causes the magma to move around, called convection currents, as a result the plates move too.
How fast do plates move? COPY: Plates move roughly the same speed as a finger nail grows, 2 -3 cm a year.
