What are the advantages of volcanoes?

A:

Quick Answer

Some of the advantages that volcanoes provide include the creation of new land, mineral deposits and beautiful landscapes that generate tourism. Active volcanoes actively cool the Earth, as their emissions remove heat from the planet's interior. Volcanic activity also helped produce the Earth's atmosphere and oceans in the past.

Deposits resulting from volcanic eruptions are used as building materials. These materials come in the form of basalt and diabase that are used in various construction elements, such as concrete aggregate, road metal and railroad ballast. Concrete shields used in nuclear reactors are also partially made up of high-density basalt and diabase aggregate.

Volcanoes also play an active role in island creation around the planet. A famous example is the Hawaiian island chain, which was created by eruptions from a volcanic hot spot in the region. Volcanic eruptions also bring forth precious gems, such as opals. Pumice stone, which is used in construction and as an excess-skin remover, also is created in volcanic eruptions.

Volcanoes are also a large source of geothermal energy. This allows regions around a volcano to subsidize their energy requirements by siphoning energy from it. Iceland, which is one of the more volcanically active countries in the world, uses geothermal energy to provide for a sizable portion of its power requirements.
