Transcript

What percentage of big earthquakes occur within 100 miles of a convergent plate boundary? About 47%

How does the distribution of these earthquakes compare to the others? These are way more powerful, and take place in major fault lines

What type of plate boundary is associated with earthquakes that have a magnitude of 7.0 or greater? A transform fault boundary.

What do you notice about the distribution of these earthquakes? They run along the plate boundaries.

What percentage of big earthquakes occur within 200 miles of a convergent plate boundary? 71%

Which places are "overdue" for an earthquake?

1) Antarctica 7) Chad 2) Brazil 8) Nigeria

3) Central Africa 9) Kazakhstan 4) Russia 10) Greenland 5) Mid Canada 6) North West Australia

What new tools or techniques are seismologists using to help them better predict earthquakes? Scientists use certain satellites to help them better predict earthquakes. It does this by looking for small electrical charges that build up as rocks in the planet's crust get strained by the massive forces of plate tectonics.

What have you learned about earthquakes and earthquake prediction? That predictions are very important, and can save many lives.

What factors influence earthquake prediction? Weather,climate, and human impact.

Where on Earth do most of the really big earthquakes strike? Along convergent plates and tectonic plates
