- 400-500 million years for one Wilson cycle to happen.
-Pangaea 2 will occur in 250 million years
Part 1: what do earthquakes tell us about the plant’s interior and plate tectonics
Part 2: plates and their margins
Part 3: earthquakes in Canada
-Seismic energy is used to map the earths interior
-drilling 12 km is a physical limit to drilling because its starting to get pretty hot down there
Earthquakes: what can we learn of the earth’s interior?
-rocks are brittle, they snap, once it snaps the energy produce is the earthquake
-the focus is the focus point under the surface of the earth, the epicentre is where the earthquake
-the line of breakage is called the fault plane, seismic waves are then produced
-there are many blind faults in the US, that can potentially produce earthquakes, but we can see.
Surface waves: they go around the surface of the planate, its usually t
