1. What is a Plate Boundary?
AF3- describe the process of plate tectonics.
AF3 - describe the distribution of continents in the future.

2. STARTER: What does this picture show?
Copy: The Earth is broken up like a jigsaw. These pieces are called plates.

3. COPY: The plates are part of the crust which float on the mantle
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.

4. How fast do plates move?
COPY: Plates move roughly the same speed as a finger nail grows, 2-3 cm a year.
