Volcanoes are important for many reasons, including benefiting nearby plants with nutrient-rich ash, providing rare species with habitats that are inaccessible to humans and livestock, and enriching the atmosphere with gases, according to Oregon State University. The Earth's life, water and atmosphere would not exist without volcanoes.Know More
Volcanic gases released from vents since the Earth's formation are responsible for the atmosphere and oceans, which led to the evolution of life, according to the United States Geological Survey. Duke University states that while meteorites and comets also brought gases that helped build the atmosphere of the Earth, volcanic activity was probably the primary source of these gases.
Over 80 percent of the surface of the Earth comes from volcanic activity. Volcanic eruptions produce everything from plains and hills to mountains and plateaus. Volcanic deposits are also used as building materials. Basalt and diabase, both produced by volcanoes, are used by humans for many things, including concrete, roofing and the construction of nuclear reactors.
Volcanoes continue to play an important role by adding to the Earth's water supply and forming new islands. Volcanic eruptions may slow climate change by releasing aerosols that help block sunlight into the Earth's stratosphere, according to a Nature Geoscience study mentioned in Time magazine.Learn more about Volcanoes
Volcanic eruptions can affect the atmosphere and climate in the immediate vicinity of the volcano and also around the entire planet if the eruption is large enough. The main effect eruptions have on the weather near the volcano is producing large amounts of thunder, lightning and rain.Full Answer >
Animals are important for many reasons, including the assistance they give to plant ecosystems, the psychological and emotional support they can offer to humans, and the knowledge gained from the human study of them. Some of the most important animals include primates, bats and bees.Full Answer >
No two volcanoes are exactly the same, as they all have differences in dimensions of their mountains and craters, as well as their relative frequency and type of eruption. Volcanoes come in cinder cone, shield and stratovolcano varieties.Full Answer >
Volcanic vents allow the Earth to release built up gases from the heat and pressure emanating from its core. Magma rises towards the surface, and as the pressure builds the magma seeks outlets through which to flow. The higher the pressure build-up, the greater the volcanic explosion.Full Answer >
