Question

classify volcanoes on the basis of the fluidity of lava

Answer 1

When studying the volcanoes in the world it is important to understand what the classification of volcanoes is and how it works. There are several factors that go into account when attempting to classify a volcano into a group and that includes things like recent activity, periodicity of eruptions, size, potential impact and others. Though it is not common to hear it volcano eruptions are actually not that rare. More often than not the classification of volcanoes refers to the life cycle and that could define them as active, extinct or dormant. However, a volcano can also be classified by the composition of the structure and that would mean that it can be a shield, conical or stratovolcano. Finally they can also be classified because of its eruption which could be quiet or explosive.
volcanoes are of three types
dormant
extinct
active

Answer 2

There are three chief types of the volcano on the basis of lava - composite, shield, and dome.

Composite Volcanoes

Composite volcanoes, often known as stratovolcanoes, are steep-sided cornets made from sheets of ash and lava outflows. The explosions from these volcanoes may be pyroclastic with the flow of lava.

Shield Volcanoes

Shield volcanoes are deep with lightly slanted sides and are constituted from sheets of lava. Explosions are typically non-explosive.

Dome (Acid Lava Cones)

Lava is much deeper which passes from shield typed volcanoes. Dome volcanoes have considerable sheerer surfaces than shield volcanoes. This is because the basalt is dense and adhesive. It cannot progress very far and before it freezes and solidifies.
