Science behind volcano

Answer 1

The Science Behind Volcanoes:-

A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash

and gases to escape from the magma chamber below the surface.

Volcanoes are generally found where tectonic plates are diverging or converging. A mid-oceanic ridge,

for example the Mid-Atlantic Ridge, has examples of volcanoes caused by divergent tectonic plates

pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates

coming together. By contrast, volcanoes are usually not created where two tectonic plates slide past one

another. Volcanoes can also form where there is stretching and thinning of the Earth's crust in the

interiors of plates, e.g., in the East African Rift, the Wells Gray-Clearwater volcanic field and the Rio

Grande Rift in North America. This type of volcanism falls under the umbrella of "Plate hypothesis"

volcanism. Volcanism away from plate boundaries has also been explained as mantle plumes. These so-

called "hotspots", for example Hawaii, are postulated to arise from upwelling diapirs with magma from

the core–mantle boundary, 3,000 km deep in the Earth.

Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. Volcanic

ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by

the high operating temperature. Large eruptions can affect temperature as ash and droplets of sulfuric

acid obscure the sun and cool the Earth's lower atmosphere or troposphere; however, they also absorb

heat radiated up from the Earth, thereby warming the stratosphere. Historically, so-called volcanic

winters have caused catastrophic famines.

Answer 2

Answer:

When rock beneath the Earth's surface gets really hot, it becomes molten or liquid. While it's still below the surface, it's called magma. Once the magma erupts to the surface through a volcano, it's called lava. The hotter and thinner the lava is, the farther it will flow. Lava can be very hot, sometimes as hot as 1000 degrees C.

This means Volcano is just a cacoon from which the lava comes out when they are really hot.
