GENERAL GEOLOGY

Detailed explanation-1: -Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. What follows is a brief description of these processes.

Detailed explanation-2: -Volcanology is a young and exciting career that deals with the study of one of the earth’s most dynamic processes-volcanoes. Scientists of many disciplines study volcanoes. Physical volcanologists study the processes and deposits of volcanic eruptions.

Detailed explanation-3: -Geologists usually group volcanoes into four main types: cinder cones, composite volcanoes, shield volcanoes, and lava domes.

Detailed explanation-4: -Geologists study the deposits of volcanoes and derive information on what the volcano has done in the past and what it might do in the future from these deposits. Geochemists study the gasses emitted from volcanoes and derive information about the magma and possibilities of an eruption.
