INDEX

When they erupt, the lava expelled from the craters accumulates on the surface and, as it cools, forms the core of the volcano. A volcano starts when the lava accumulates and has to come out.

When does it happens?

WHERE DO VOLCANO ERUPTS?

Most Earth’s volcanoes, take place along the Ring of Fire. The ring of fire, also called as the Circum-Pacific Belt, is a path along the Pacific Ocean, characterized by active volcanoes and earthquakes.

Volcanoes erupt when molten rock, called magma, rises to the surface. Magma is formed when the earth’s melts. Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another. As the magma rises, bubbles of gas form inside it. Liquid magma erupts through openings or vents the earth’s crust before flowing onto its surface as lava.

WHY DO volcanoes ERUPTS?

What happens?

When a volcano is hot, it explodes, and very hot lava begins to come out for a long time and destroys all of nature and the town. And when the lava runs out it dries up and turns into a kind of black lava stone.
