What does magma need to do for a rock to form?
Magma needs to cool and solidify to form a rock. This process can happen underground, resulting in intrusive rocks, or at the surface, leading to extrusive rocks. The rate of cooling and the mineral composition of the magma will determine the type of rock that forms.
If lava is to hot in a volcano can it burn the volcano down?
This is a silly question...No! Magma (not lava) can melt (not burn) and include some material sorrounding it but could never melt an entire volcano as it would cool down and become solid in doing so.
What is an opening that leads from the crater of a volcano down to pools of magma?
A volcanic vent or conduit is an opening that leads from the crater of a volcano down to pools of magma below the surface. This conduit allows magma to travel from the magma chamber to the surface during an eruption.
When the magma flows down the side of the volcano we call it?
lava!
An opening that leads from the crater of a volcano down to pools of magma?
a vent
How would you use the word magma in a sentence?
there was much magma after the volcanic eruption
Is lava magma?
yes. magma is the lava that is in the volcano and lava is the magma that is outside a volcano
Where is the magma in a volcano?
In a magma chamber
What is magma calle when it comes out of a volcano?
When magma comes out of a volcano, it is called Lava.
How can you tell that Mount Fuji is a composite volcano rather than a shield volcano?
The volcano is very wide it means that it has mafic magma. The composite volcanoes have mafic magma in them. When the volcano erupts the lava flows down really fast, but hardens really slowly causing the volcano to widen its width size.
Do volcanoes have to be a specific type of rock for lava not to melt through?
No. Some melting of rock occurs in and under a volcano from the magma, but it is only a small fraction of the volcano's rock. There are two reasons for both stemming from the first law of thermodynamics: energy can neither be created nor destroyed, only converted between different forms. This means that for magma or lava to heat up and melt a rock, the lava itself must cool down. In terms of temperature, the magma in a volcano is closer to solidifying than the rock is to melting. Second, the volume of solid rock in a volcano is much larger than the volume of magma.
What is the origin of obsiadan?
If you are asking about how they were formed magma from volcano that are shot in the air of quickly spewed out causing the magma to cool very quickly forming a very smooth surface on obsidian. Becuase the magma cooled so fast it couldn't slowly cool into a rough textured rock.
