Volcanoes generally preserved geologic rock record eroded . However, materials erupted volcanoes found preserved rock record. From learned types volcanoes, infer type volcano erupted an area-based type volcanic deposits found layers rock? Give specific examples, briefly discuss materials linked types volcanoes.

Volcanoes are some of the most interesting and at the same time intriguing manifestations of nature. They have been the object of study for decades and all types of technologies were used to either understand the way in which these natural phenomena take place in the sense of eruption or to have a clearer image on the placement in time and geological eras of these structures.

Volcanic mountains or constructions usually are formed as a result of constant eruptions and sedimentation of the lava. However, their height or structure is not necessarily a robust one and most often they erode in time, leaving behind only parts of volcanoes or different other remains (Lockwood and Hazlett, 2010). Even so, through advanced techniques, the ages of volcanoes as well as the different composition of the volcanoes can be determined.
The use of relative age dating and radiometric dating is very important in this sense.

Depending on the different composition of the materials in one area of a volcano, it can be determined with relative precision what type of volcano erupted and when. More precisely for instance, "The degree of violence of an eruption depends principally on the chemical composition of the magma. Of major importance is the interplay between the proportion of silicon dioxide (SiO2 or silica ), which controls the viscosity of the magma, and volatile components, such as water, carbon dioxide, and sulfur dioxide" (U.S. Dept. Of Interior, 2012). In this sense the composition of the magma is essential for the potential damage an eruption can cause and at the same time for the predicting the type of volcano one structure is so that further preventive action can be taken. Thus, "magmas….....
