Floating on top of the magma is the Earth’s rocky crust.

The crust is made up of tectonic plates. These huge plates are moved slowly by magma currents below, sliding past each other with     5    . If a plate is forced down     6     another and gets     7    , pressure will build up until the stressed rocks suddenly     8     apart, causing     9     ground movements called earthquakes. The point where the rocks suddenly jolt or break is called the epicentre, from which, powerful shock waves     10     out in all directions.
