What happens to the lava in the volcano?
Technically, it is not lava until it pours out of the volcano. While it is in the volcano it is still magma. What is not ejected in the form of lava might sink and form a plug, allowing the magma to once again build up in the volcano's magma chamber.
What is the form of magma when it thrown out from the volcano?
Lava.
What features form a hot spot volcano form?
magma
Does a volcano form when magma reaches earths surface?
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
How does a volcano form into a mountain?
Over time the magma chamber found inside volcanos is cut off from the mantle by tectonic plate movement. Without constant exchange of hot magma from the mantel to replace the colder magma in the volcano, (convection), the magma inside the volcano hardens into igneous rock.
Which factor plays a major part in determining the form of a volcano?
The composition of the magma is a major factor in determining the form of a volcano. Magma with high viscosity tends to form steeper-sided volcanoes, while low viscosity magma results in more gently sloping volcanoes. Additionally, the frequency and type of volcanic eruptions can also influence the shape of a volcano.
Suppose a volcano that is about to erupt contains mafic magma. The mafic magma has a very low silica content. what types of igneous rocks will the volcano most likely form?
basalt
What two properties of magma determine what kind of volcano will form?
The silica content and the gas content of magma are two properties that determine what kind of volcano will form. Magma with low silica content and low gas content tends to form effusive, shield volcanoes, while magma with high silica content and high gas content tends to form explosive, stratovolcanoes.
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
How does magma inside a volcano become a lava flow outside?
Magma inside a volcano can become a lava flow outside when pressure builds up inside the volcano, causing the magma to erupt through the volcano's vent or fissures. As the magma reaches the Earth's surface, it is then referred to as lava. Once outside the volcano, the lava can flow downhill and solidify to form igneous rock.
A What happens inside the volcano during its eruption?
magma flows up to form the eruption
