Match the appropriate earthquake focus classification with the locations on the diagram:
For each item below, use the pull-down menu to select the letter that labels the correct part of the image.
Subducted slabs remain rigid to about 1500 km down.
It seems that the subducted slab has heated sufficiently by that depth so that it loses its rigidity.
It seems that the subducted slab has cooled sufficiently by that depth so that it loses its rigidity.
Subducted slabs become more rigid below 700 km down.
leads to a realistic view of the Earths interior
leads to a better prevention of property and life casualties
leads to the development of tsunami (tidal waves)
leads to the development of the plate tectonic theory
Earthquakes that have shallow foci are located at divergent plate boundaries.
Earthquakes provide important evidence for plate tectonics.
Earthquakes that have shallow foci are located at transform plate boundaries.
Earthquakes show the difference between continental and oceanic plates.
Earthquakes that have deep foci are located in association with subducted slabs.
