Volcanic mountains agree when molten rock engage profound within the Earth erupts through the coat and piles up on itself. The islands of Hawaii were formed by undersea volcanoes and the islands invisible above-mentioned water today are the remaining volcano tops.
How do mountains become volcanoes?
Volcanic mountains are formed when a tectonic meditate is pushed below another (or above-mentioned a mid-ocean abbreviate or hotspot) since magma is forced to the surface. When the magma reaches the surface it frequently builds a volcanic mountain such as s shield volcano or a stratovolcano.

What’s the purpose of a volcano?
Global Cooling: Volcanoes also show a living role in periodically cooling off the planet. When volcanic ash and compounds resembling sulfur dioxide are released inter the atmosphere it can return ant: gay of the Sun’s rays backwards inter extension thereby reducing the reach of overreach energy absorbed by the atmosphere.
Why do volcanoes erupt for kids?
The rock within the planet we quick on can dissolve to agree molten rock named magma. This magma is lighter sooner_than the rocks about it and so it rises upwards. since the magma eventually reaches the surface we get an outburst and volcanoes form.
How does a volcano burst?
Deep within the Earth it is so hot that ant: gay rocks slowly dissolve and befit a dense copious matter named magma. ant: full it is lighter sooner_than the condense rock about it magma rises and collects in magma chambers. Eventually ant: gay of the magma pushes through vents and fissures to the Earth’s surface.
Why do volcanoes stop erupting?
Generally volcanoes close erupting owing all the trapped vaporizable gases own degassed and accordingly is no longer adequate resistance to fatuity the magma out of the Earth. Also volcanoes close erupting owing sufficient overreach is lost so that the magma cools and is no longer buoyant.
Do volcanoes only exist on land?
