The viscosity of magma affects its ability to flow. For Krakatoa, the magma was characterized by high viscosity due to its high silica content, causing pressure buildup leading to explosive volcanic eruptions. The high viscosity of the magma at Krakatoa contributed to the violent nature of its eruptions in 1883.
What else can I help you with?
What was Krakatoa's viscosity?
Krakatoa's magma viscosity was estimated to be relatively low, indicating it was more fluid-like. This low viscosity contributed to the violent explosive eruption in 1883, producing devastating volcanic events such as pyroclastic flows and tsunamis.
Did Krakatoa have high viscosity lava?
No, Krakatoa is known for its explosive eruptions due to its low-viscosity lava. This type of magma allows gas bubbles to rise quickly to the surface, resulting in powerful and destructive eruptions.
What does viscosity have to do with eruptions?
The viscosity of magma or lava will determine whether or not the eruption is explosive or quiet. Higher viscosity magma can result in explosive eruptions. Lower viscosity magmas tend to flow more freely.
Is ultramafic magma high in viscosity?
No. Ultramafic magma would have a low viscosity.
Which conditions make for a violent volcanic eruption?
Magma with low viscosity

Does Krakatoa make pillow lava?
No. Pillow lava is basaltic, low-viscosity lava. Krakatoa is a stratovolcano with a style of ereuption more characteristic of high-viscosity andesitic lava.
What is meant by the term viscosity when used in describing magma?
The ease with which it flows or how thin or thick it is. the more solid it is the higher the viscosity. As in Oil the thicker it is the higher the viscosity machine oil low viscosity, gearbox oil high viscosity.
What 3 factors determine magma viscosity?
The three elements that determine viscosity in magma are:TemperatureSilicaOxides (gases)Viscosity changes the way in which magma will flow. Magma with low viscosity will flow much more easily than high viscosity magma.
What mainly determines the viscosity of a magma?
Viscosity is the measure of a liquids resistance to flow. In the case of magma, the hotter it is, the lower the viscosity.
What is the volume of Krakatoa's magma?
the volume is 1800 mph
Compare and contrast the three types of magma?
Basaltic Magma is typically forms when rocks in the upper mantle melt...Andesitic Magma is found along continental margins....Rhyolitic Magma forms when molten material rises and mixes with the overlying silica-and water-richcontinental crust...All 3 of them is a magma.
How big is Krakatoa's magma chamber?
Krakatoa's magma chamber is estimated to be around 40 cubic kilometers in volume. This large magma chamber plays a significant role in fueling the volcanic activity and explosive eruptions of Krakatoa.
