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?
you smell
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 that is low in silica which is thin and runny
Which type of front usually causes the most violent weather?
A cold front usually causes the most violent weather
What type of magma causes quiet volcanoes?
magma that is low on silica & thin and runny & it flows easily
What type of eruptions does Mt Pinatubo have and what causes the eruption to be violent or non-violent?
what causes a eruption to be liolent is the type of lava -felsic lava is non-violent -mafic lava is violent
The type of magma that often produces a violent eruptions can be described?
Thick due to high silica content.
The type of magma that often produces a violent eruption can be described as?
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 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! :)
