Since there are many possible measures of the price level, there are many possible measures of price inflation. Most frequently, the term inflation refers to a rise in a broad price index representing the overall price level for goods and services in the economy. 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.

One other way mountains form is as the result of volcanic activity below Earthâs surface. Sometimes molten rock called magma gets pushed up toward the surface. When that happens, it cools and forms hard rock. Eventually, the softer rock above it erodes to reveal a dome-shaped mountain below. If the magma actually breaks through to the surface, you get a volcano! Mountains can also form by way of erosion. In an area with a high plateau, rivers and streams can carve away stone in the form of deep channels. Over millions of years, what is left is a mountain between deep river valleys!
