What is the difference between Volcano as well as volcanism?
Is volcanic eruption and also volcanism the exact same?Volcanism (or volcanicity) is the phenomenon of eruption of molten rock (lava) onto the surface area of the Earth or a solid-surface planet or moon, where lava, pyroclastics and also volcanic gases erupt via a break in the surface called a vent.
What triggers volcanism?When enough lava builds up in the lava chamber, it requires its way as much as the surface area and erupts, commonly triggering volcanic eruptions. In the ocean, volcanoes appear along cracks that are opened up in the ocean flooring by the dispersing of two plates called a mid-ocean ridge.
What are the types of volcanism?Rock hounds normally team volcanoes into four major kinds– cinder cones, composite volcanoes, guard volcanoes, and also lava domes.

What can you say concerning volcano?
A volcano is a hill that opens down to a swimming pool of liquified rock below the surface of the planet. When pressure accumulates, eruptions occur. In an eruption, gases and rock shoot up via the opening as well as overflow or fill the air with lava fragments. More than 80% of the planet’s surface area is volcanic in origin.
What is volcano brief answer?
A volcano is an opening in the earth’s crust where lava, ashes, as well as gases escape. Beneath a volcano, liquid magma consisting of dissolved gases climbs with cracks in the Earth’s crust.

It also consists of percentages of dissolved gases such as water vapor, co2, and sulfur. The high temperatures and stress under Earth’s crust keep lava in its fluid state. There are 3 standard types of lava: basaltic, andesitic, and rhyolitic, each of which has a different mineral make-up.
Can a volcano appear without warning?
Steam-blast eruptions, however, can accompany little or no warning as superheated water flashes to steam. Remarkable precursors to an eruption may include: A boost in the regularity as well as intensity of felt quakes. Recognizable steaming or fumarolic activity and brand-new or enlarged areas of hot ground.
