GEOLOGY

Detailed explanation-1: -Strictly speaking there are two broad types of volcano, a stratovolcano and a shield volcano, although there are lots of different volcanic features that can form from erupted magma (such as cinder cones or lava domes) as well processes that shape volcanoes.

Detailed explanation-2: -The overall size of a volcano is determined by the total volume of lava that has erupted. The shape of a volcano is largely determined by the type of lava that has erupted, and importantly, its viscosity. Viscosity is a fluid’s resistance to flow. Water, for example, is a low viscosity fluid.

Detailed explanation-3: -Characteristics of a volcano or volcanic mountains Magma chamber contains molten rocks and gases under high pressure. Conduit is a pipe-like structure through which magma comes out and it opens into the main vent. The depth of the magma chamber is usually 1km to 10 km.

Detailed explanation-4: -A volcano is formed by eruptions of lava and ash. Volcanoes are usually cone shaped mountains or hills. When magma reaches the Earth’s surface it is called lava. Volcanic eruptions can happen at destructive and constructive boundaries, but not at conservative boundaries or collision zones . More items
