Which type of lava will flow the fastest because it is low in silica?
Lava Type Silica Content Approximate Flow Rate basaltic least 30-60 km/hr andesitic in between 10 km/hr rhyolitic most 1 km/hr 4 more rows ?
And another question, where is the greatest volume of magma produced?
The greatest volume of magma is produced along the oceanic ridge system in association with seafloor spreading. Correspondingly, which statement describes the composition and viscosity of the lava associated with shield volcanoes? Which statement describes the composition and viscosity of the lava associated with shield volcanoes? Lava from shield volcanoes is mafic and has a low viscosity.
Thereof, what is fluid viscosity?
Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. Subsequently, what type of magma has the lowest silica content highest silica content? MAGMA COMPOSITION AND ROCK TYPES SiO2 CONTENT MAGMA TYPE VOLCANIC ROCK ~50% Mafic Basalt ~60% Intermediate Andesite ~65% Felsic (low Si) Dacite ~70% Felsic (high Si) Rhyolite
In respect to this, which rock is lower in silica mafic or felsic?
Since igneous rocks are characterised by silica content in them, mafic is the one with less silica content (approx. 45-55%) while felsic is the one with a greater silica content (approx. 70-90%). What is an igneous rock with a low silica content that flows easily? Lava that is low in silica, such as basalt lava, flows easily and spreads out in thin sheets over great distances.
- What are the 3 types of lava flow?
The debris cloud known as Cassiopeia A is an example of the final phase of the stellar life cycle. It took about 11,000 years for the light from the explosion to reach us.
- What is a pahoehoe lava flow?
Historical earth images going back more than forty years can be found in the public data archive hosted by Earth Engine.
- Is the moon orange because of the fires?
Some of the components of bone and teeth may be dissolved in magma, but they won't melt.
- Do composite volcanoes have high silica content?
- What type of star is our Sun low or high mass?
- Which layer slowly deforms and has a plastic like flow?
- What type of rock is formed when hot lava is cooled and hardened?
