about volcanoes
volcanoes are a mountain full of magma. during a eruption magma rises up to the top of the mountain and then becomes lava. lava is known to burn alot of things it burns nature

Volcanoes erupt because of density and pressure. The lower density of the magma relative to the surrounding rocks causes it to rise (like air bubbles in syrup). It will rise to the surface or to a depth that is determined by the density of the magma and the weight of the rocks above it.

amazing volcano facts
1.The most dangerous volcano today is Popocatépetl, nicknamed El Popo, which is just 33 miles from Mexico City. El Popo is still active, sending thousands of tons of gas and ash into the air each year.

2. A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur.

Thank you! for watching
of the eruption
this is a volcano eruption in Papa New Guinea
your questions
biggest volcano recorded is the Mauna Loa in Hawaii It is a massive shield volcano constructed by countless lava flows. When measured from the base to the top, the pile of lavas measures more than 17,000 m (56,000 ft)!

volcanoes form when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.

volcanoes erupt when it's underneath the surface, the molten rock is called magma. When it reaches the surface, it erupts as lava, ash and volcanic rocks. With each eruption, rocks, lava and ash build up around the volcanic vent where the material blasts out of. The nature of the eruption depends on viscosity of the magma
your questions 2
lava is red because Lava is defined as rock that in its molten form, that reaches the surface of the earth form the eruption of a volcano. It is red because it glows from the high temperatures that it possesses of more than 7000 degrees centigrade. Lava is a name derived from the Italian word for stream, which is derived from the verb lavare which means to wash.

you can cook stuff on a volcano a resturaunt proves that you can Located on a Spanish island called Lanzarote, northwest of Morocco, El Diablo is a unique restaurant where the chefs have access to a volcano of their own. Of course, it isn’t like a lava-spewing mountain, because if that were the case there would be no question of leisurely eating. No, this volcano is more like a hole in the ground, through which volcanic heat erupts from the deeps of the Earth.

your questions were brilliant thankyou
