The Consumer Price Index (CPI), the Personal Consumption Expenditures Price Index (PCEPI) and the GDP deflator are some examples of broad price indices.
Volcanic Mountains. As the name suggests, volcanic mountains are formed by volcanoes. Volcanic Mountains are formed when molten rock (magma) deep within the earth, erupts, and piles upon the surface. Magna is called lava when it breaks through the earth's crust.When the ash and lava cools, it builds a cone of rock.olcanic Mountains are formed when molten rock (magma) deep within the earth, erupts, and piles upon the surface.

All three rock types - igneous, sedimentary, and metamorphic - make up a portion of the rock cycle. Igneous rocks are rocks that formed directly from magma and can form either in the earth or on its surface. Igneous rocks can weather and be compressed to form sedimentary rocks, rock made up eroded material broken off of other rocks and cemented together, and both of these can be transformed into metamorphic rock.
