Currents and Tectonic Plates’
2. Now put these 8 sentences in the correct order
A. The process is known as convection currents
B. The rising and falling magma creates circular currents with the mantle
C. The less dense magma then starts to rise towards the crust
D. The cooling magma becomes denser and begins to sink
E. As the magma warms it expands and becomes less dense.
F. It are these currents that create friction with the crust above and causes it to move.
G. Magma (semi-molten rock) near the outer core is heated.
H. As the magma nears the crust it begins to cool.
