POP QUIZ!!!!!! WHICH PART OF THE EGG REPRESENTS EACH PART OF THE EARTH???
When Plates Move… The face of the Earth changes…
With the build-up of enough pressure the Earth will break and the plates will move suddenly causing an earthquake. This “break” place is called the EPICENTRE. • Cool fact: An earthquake shakes the planet about every 3 minutes or 180 000 times each year. • Q: Look at a map and locate a region that you expect there to be a high frequency of earthquakes in North America. Why there?
Think…Talk…Record… • Q 1: Do you expect there to be plains very close to the boundaries of different plates? Explain your thinking. • Q 2: If you were looking to move to a part of the world that was relatively unaffected by natural disasters, where should you go? Use the knowledge gained in this lesson to explain why.
