Pinatubo is just one of five major volcanoes in
the Philippines. Eruptions from these subduction-related
volcanoes will likely continue occurring. Each eruption
initiates a series of interactions among Earth's
spheres. The cumulative effect of continually adding
new geosphere materials to Earths surface
in this region will ultimately change the world.
8. Predict how Earth sphere interactions
in this region will change in the future.
