Compare these 2 images. Where are earthquakes and volcanoes most likely to be found?
Convection cells are the driving force behind plate tectonics. Where do they occur?


What is the S-P interval time for Talca?

What is the S-P interval time for Santiago?

What is the S-P interval time for Orsorno?

The dark diagonal line on the graph represents the relationship between the S-P time interval and the distance the waves have traveled.
Each city is marked on the graph.
What is the distance from the Talca station (red) to the epicenter?
Circles were drawn using the epicenter distances for each location.
The epicenter is located at the intersection of the three circles.
Using the drawing tools to mark the location of the earthquake.
At divergent plate boundaries, the plates each other.
At convergent plate boundaries, plates each other
What is subduction?
Which feature would you expect to find at a convergent subduction boundary?
Which feature would you expect to find at a convergent collision boundary?
At transform plate boundaries, the plates each other
What occurs when the energy is released at a transform boundary?
What is the distance from the Santiago station (green) to the epicenter?
What is the distance from the Orsorno station (purple) to the epicenter?
