Volcano is an opening in Earth's surface through which lava, boiling gases, and stone fragments erupt. Also known as an opening, which forms when melted rock from deep within Earth blasts through the surface. Volcanoes are very enormous in width as well as length. Most volcanoes are mountains, which were built up around the opening by lava and other materials thrown out during eruptions. Without a doubt volcanoes provide necessary services to nature in the world. The eruption of lava constructs land to the earth and seafloor, and volcanic products provide abundant soil for agriculture. Some scientists even theorize that the action of volcanoes brought life-giving water to the earth's surface eons ago, allowing life to spring forth. Throughout centuries, volcanoes have played an amazing role in the history of our planet, vegetation and our species. Volcanoes also are known to be the main causes of many casualties and terrible and devastating fires and can eradicate an entire neighborhood in hours.
Today known the biggest volcano is Mauna Loa on the island of Hawaii. The base of Mauna Loa rises from the sea floor five kilometers to sea level, then another four kilometers above the sea, making Mauna Loa from base to summit nine kilometers high. Mauna Loa last erupted in March and April 1984.
Eruptions of volcanic mountains are one of its amazing highlights. During various eruptions, huge fiery clouds rise over the mountain, and Reddish/yellowish Rivers of lava rush forward along its sides. In some other eruptions, red-hot ash and cinders shoot out the mountaintop, and huge chunks of hot rock are blasted high into the air. In some cases eruptions have been notorious in acting so ferociously to facilitate the potency in blowing an entire mountain apart.
