In addition to these comprehensive theories of unemployment, there are a few categorizations of unemployment that are used to more precisely model the effects of unemployment within the economic system.
Best Answer: Earthquakes tend to occur on either side of the Pacific Ocean, including the Western coast of North and South America, as well as East Asian islands like Japan. This is because the crustal plates of these continents are moving and sliding over the plates that make up the Pacific Ocean floor. These areas are known as the Ring of Fire because they also contain many active volcanoes. Four out of every five earthquakes occur in the Ring of Fire.
Also similar to earthquakes, different kinds of volcanoes occur along different types of plate boundaries. Most of the volcanic eruptions that make the news, such as the 1980 Mount St. Helens eruption, take place near subduction zones.This type of volcano is represented by green triangles in Figure 2.hese observations about the distribution of earthquakes and volcanoes helped geologists define the processes that occur at spreading ridges and subduction zones. In addition, they helped scientists recognize that there are other types of plate boundaries.
