Volcanic materials
ultimately break down and weather to form some of the most fertile soils on Earth
, cultivation of which has produced abundant food and fostered civilizations. The internal heat associated with young volcanic systems has been harnessed to produce geothermal energy.
What are the importance of volcanoes?
“It gives us
really fertile soils
, which are great for farming and crops.” Volcanoes also provide a good environment for the formation of new habitats for animals, plants and insects, she said. Hot springs and geothermal energy are additional benefits.

responsible for land
, another necessity for many life forms.

can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields. Lava can kill plants and animals too.
How energy from the volcano is being used?
Conventional
geothermal energy
utilizes steam from natural sources such as geysers, or by drawing water from the hot, high-pressue depths of the Earth. … The hot vapors are then used to drive electric turbines.
Are volcanoes bad for the environment?
Volcanic eruptions
can be extremely damaging to the environment
, particularly because of a number of toxic gases possibly present in pyroclastic material. … Carbon dioxide emitted from volcanoes adds to the natural greenhouse effect.
