It's amazing to think that the land we're standing on is actually
part of a huge plate floating on incredibly hot liquid rock deep
inside the earth. |
| Francis |
Yes, and the earth's crust is actually made up of lots of these
tectonic plates, which are moving against one another all the time. |
| Bill |
That's why we have earthquakes. |
| Francis |
That's true. And the places where these plates come up against one
another are called faults in the earth's crust.
Faults are like cracks all over a teapot,
except that they're moving all the time. |
| Bill |
So the surface of our earth is actually quite unstable. |
| Francis |
Well I think the tsunami disaster showed that very clearly. |
