Main Body
Volcanoes refer to the opening in the earth's surface from where magma and lava, among others, flow outside on the surface. Volcanoes are destructive in nature as: → hot lava destroys everything that comes in between is agricultural fields is habitations → causes economic loss. But, volcanoes are also critical for existence of human life → (1) lead to mixture of minerals
Silica: good for soil fertility (2) expulsion of aerosols into the atmosphere → lead to cooling (3) helps in maintaining mineral cycles: eg Phosphorous cycle (4) Helps in understanding (scientific research) → eg paleo magnetism. Volcanoes are thus both dangerous and critical for human life. Research into volcanoes is necessary for a better understanding of earth's processes.
