What else can I help you with?
What affects the type of igneous rock that is formed?
Mineral composition of the magma, Rate of cooling of the magma, Temperature of the magma, Presence of volatiles and Amount of water present in the magma.
When magma does crystallization what rock does it make?
That entirely depends on what type of magma it is and under what conditions it crystallizes. If you are looking for a general rock type, the answer is igneous, but that's very general.
What type of magma does Mt Etna have?
The composition of Mt. Etna is basaltic.
What type of magma does nevado del ruiz have?
Nevado del Ruiz is a stratovolcano, so the composition of the magma likely varies over time. The tragic eruption of 1985 involved magma of andesite or dacite composition.
What is Magma injected into older rock?
That is known as an "intrusion". The magma (lava) is forced under pressure into cracks and fissures within the older rock. There are some good examples of this type of formation in Yellowstone caldera.
The type of magma that often causes a violent eruption can be described as having?

What type of eruptions does Mt Pinatubo have and what causes the eruption to be violent or non-violent?
Mt. Pinatubo is known to have explosive eruptions. The violence of an eruption is influenced by the amount of dissolved gas in the magma, the viscosity of the magma, and the presence of water or other fluids. If the magma has high gas content, is highly viscous, and interacts with water, it can lead to a more violent eruption.
What type of magma produces violent reaction?
Acidic lava is very viscous, and thus will harden and block the vent. The magma will force its way out through the vent and create a violent explosion.
What type of magma causes quiet eruption?
Magma with low viscosity, such as basaltic magma, typically causes quiet eruptions. This type of magma flows easily and allows gases to escape, resulting in relatively gentle eruptions with less explosive activity.
What type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
The type of magma that often produces a violent eruptions can be described?
Thick due to high silica content.
Which factors determine how violent an eruption will be?
· It is determined by the primary factors of the magma's Temperature, its Composition, and the amount of Dissolved Gases it contains.
How does the viscosity of the magma influence the type of eruption?
The viscosity of magma affects whether or not magma flows away or piles up during an eruption. Viscosity, along with volatiles (dissolved gases) and volume determine whether you have a peaceful eruption or a very violent one.
What magma causes powerful and explosive volcanic eruptions?
Powerful and explosive volcanic eruptions are primarily caused by magma that is high in silica content, resulting in a viscous, thick consistency. This type of magma, often referred to as rhyolitic magma, traps gases such as water vapor and carbon dioxide. As pressure builds due to the accumulation of these gases, it can lead to violent eruptions when the magma finally escapes. In contrast, basaltic magma, which is lower in silica, tends to produce more effusive eruptions.
What kind of magma produce violent volcanoes eruptions?
Rhyolitic magma. This type of magma is found where the gases can't escape like in volcanic eruptions. Because the gas can not escape, the magma becomes viscous, resulting in the explosions being violent and unpredictable. The other type of magma is Basaltic magma. This can be found where continent plates are pulling away from each other and the magma is nearer the surface. This allows the gas to escape and therefore the magma is less viscous and doesn't result in explosive volcanoes, here eruptions are gentle and 'rifts' are more likely, where lava is persistent. I hope this helps! :)
What type of magma is most likely to cause a volcano to explode?
Thick, viscous magma builds resists eruption more than a thinner, runnier magma. This causes the thick, viscous magma to build up far more pressure which leads to far more violent eruptions. Shield volcanoes generally have a thinner, runnier magma, which is why their eruptions have longer, less violent cycles, such as Kilauea which has been erupting non-stop since 1983. Stratovolanoes generally have a thicker, viscous magma which results in incredibly violent, explosive eruptions which eject large masses of rock and ash far up into the air, such as the eruptions of Mt. St. Helens and Krakatoa.
What determines the type of mineral formed by cooling magma?
The rate of cooling of the magma determines the type of mineral formed by the magma or lava..
