How does volcanoes from and erupt?
Volcanoes erupt when pressure from inside the earth pushes magma through a weakness in the earth's surface. As more and more magma erupts, the volcano is formed and grows.
Is lava inside or outside a volcano?
Lava is found inside a volcano, typically in chambers deep beneath the surface. It erupts through openings in the Earth's crust during volcanic eruptions, flowing outwards onto the volcano's slopes or surrounding areas.
What is the name for lava before it leaves the volcano?
its magma before it reaches earths surface. lava is when its at earths surface
What is the liquid materials inside the earth?
the liquid materials inside the earth is the magma. Or in another words, the lava which erupts from volcanoes
What igneous rocks form above the earths surface?
Igneous rocks that form above the Earth's surface are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks form when magma erupts onto the surface and cools quickly.
How does magma change the earth surface?
When magma erupts on to the earth's surface it hardens and forms new land.It depends on if your talking about magma or lava, lava is on the surface of the Earth and magma is inside (underground).
Why man floats in the surface of water after death?
As the body decomposes, it releases gasses from the inside almost like a ballooning effect causing the body to "float".

What is the area where magma collects inside a volcanoe before it erupts?
Magma chamber.

Does molten material erupts inside the central valley of the mid-ocean ridge?
Yes.
Why electric bulbs don't have air inside?
Electric bulbs do have the inert gasses inside and not oxygen to avoid explosions.
How do you be prepared before a volcano erupts?
Wear gas masks, stay inside, and be prepared to evacuate if neccicary.
What force that forces magma out of a volcano?
Magma erupts out because of immense pressure inside the earth's crust.
How does heat and gases coming to the top cause a volcano erupt?
The heat, not so much. Gasses and pressure are greater factors. Pressure undreground forces magma through cracks in the ground. As the magam approaches the surface the decrease in pressure causes the gasses to come out of solution, somtimes violently, causing material to fountain or explode out. It is somewhat similar to opeing a can of soda that has been shaken. However, evenwithout the gasses, the pressure inside the earth may be enough to force magma onto the surface as lava, especially with low-viscosity magmas.
