It is not. It is forced up through the Earths mantel and then through the volcano. The volcano itself is just solidified magma (called lava as it exudes from the volcano).
The area where magma collects inside a volcano before an eruption is called the magma chamber. This is a reservoir beneath the volcano where molten rock accumulates and builds up pressure, eventually leading to an eruption.
Before an eruption, magma moves into the area beneath the volcano and collects in a magma chamber, or reservoir. As it comes closer to the surface, the magma releases gases. These events can offer valuable clues about the likelihood of an eruption.
Magma is not an eruption. Magma is a mixture of molten minerals and dissolved gas that is underground. All volcanic eruptions, apart from phreatic eruptions, involve magma.
The time it takes for magma to heat up before an eruption can vary significantly depending on several factors, including the type of magma, the geological setting, and the conditions within the magma chamber. In some cases, magma can accumulate and heat over thousands to millions of years before erupting. In other scenarios, changes in pressure, temperature, or the influx of new magma can trigger an eruption after just a few days to weeks. Ultimately, predicting the exact timing of an eruption is complex and depends on the specific dynamics of each volcanic system.
Magma chamber. This is a large underground reservoir that holds the molten rock before it is forced to the surface during an eruption. The size and depth of the magma chamber can vary depending on the volcano.
magma is lava that has not been exposed to the air before eruption.
A Magma Chamber is a space (that can change size) at a depth below a volcano in which magma can accumulate prior to an eruption. A volcanic vent is a conduit connecting the magma chamber to the surface. It is though this that the magma flows during an eruption.
The earthquakes are caused by the movement of magma underground and the breaking of rocks by that magma.
No, it is called magma before eruption and lava afterwards.
The area where magma collects inside a volcano before an eruption is called the magma chamber. This is a reservoir beneath the volcano where molten rock accumulates and builds up pressure, eventually leading to an eruption.
The composition of the magma affects how explosive a volcanic eruption will be.
If the magma is more viscous, the eruption is stronger.
Yes, there were several earthquakes leading up to the Eyjafjallajökull eruption in 2010. These earthquakes were caused by the movement of magma beneath the volcano, which eventually led to the eruption.
No. A magma chamber is the area under a volcano where molten rock is stored. A caldera is a depression in the ground formed during an exceptionally violent volcanic eruption. A caldera forms when a volcano drains a large volume of magma from the magma chamber, causing the volcano to collapse into the space left behind.

If the composition of the magma is high in silica, the eruption will be explosive. The Eruption of Mt. St. Helens was an explosive eruption. If the composition of the magma is low in silica, it will produce a quiet eruption. The eruption(s) of Mt. Kilauea are quiet eruptions.
