Earthquakes have 5 stages:
Crazy Caramel coloured donkeys plays super rugby every second weekend
1) Convection currents (see below)
2) Continental drift
3) Pressure and stress energy
4) Release energy
5) Seismic waves
Thinking Questions:
Why is continental drift like a bubble bath?
What would happen if the core was cold ?
Would people feel EQS if seismic waves did not exist?
What would happen if there was no pressure and stress energy ?
Once again iw as away, so Gareth will need to fill in on how this was taught etc.
