What mineral that affects magma thickness?
The mineral that affects magma thickness is silica. Magma with high silica content tends to be more viscous, resulting in thicker magma. Conversely, magma with low silica content is less viscous and flows more easily.
What three things indicate the thickness of magma?
Silica content: Magma with high silica content tends to be more viscous and therefore thicker. Temperature: Hotter magma is usually less viscous and flows more easily. Gas content: The presence of dissolved gases, such as water vapor and carbon dioxide, can affect the viscosity of magma, making it thicker.
What is a magma's viscosity directly related to?
A magma's viscosity is directly related to its temperature and silica content. Higher temperature and lower silica content typically result in lower viscosity, making the magma more fluid and runny. Conversely, lower temperature and higher silica content lead to higher viscosity, resulting in a thicker, more sticky magma.
Why is a high temperature require to form magma at the oceanic ridges than in the continental crust?
High temperatures are required to form magma at oceanic ridges because the mantle beneath these regions is hotter due to its proximity to the Earth's core. In contrast, the continental crust is thicker and insulates the mantle, resulting in magma formation at lower temperatures. Additionally, the higher pressure at oceanic ridges can also contribute to the higher temperatures needed for magma formation.
What list places the magma What list places the magma types in order of decreasing?
basaltic,andesitic,rhyolitic
What effect does silica content have on the magma?
Silica content makes the magma thicker which can cause a more explosive eruption, and also make it so more gases aer open to be trapped
Is it true that the more sycila magma contains the thicker the magma is?
no, it's silica
Does silica make magma thicker?
yes is does
What do both silica and water do to magma?
Silica is silicon dioxide. Is is perhaps the most common compound on earth. In magma the amount of silica is key in determining the viscosity. More silica leads to a more viscous magma.
Why is silica rich magma explosive?
This is because silica-rich magma is thicker. The thicker the magma, the chance for the dissolved gas in there to escape is less likely. This causes an explosion. When the gases do escape, they cause an even bigger explosion
Does the increase in silica increase the viscosity of a magma?
it is normally intermediate flow because of the silica content.
Magma is hot liquid rock that makes what power possible?
magma is hot liquid rock that makes what power possible?
How does silica affect the shape of a volcano?
High silica content in magma can lead to explosive eruptions and the formation of steep-sided volcanoes, such as stratovolcanoes. This is because high silica magma is thicker and more viscous, which traps gases and builds up pressure before erupting violently. The high viscosity of silicic magma prevents it from easily flowing, resulting in the steep shape of the volcano.
What mineral that affects magma thickness?
The mineral that affects magma thickness is silica. Magma with high silica content tends to be more viscous, resulting in thicker magma. Conversely, magma with low silica content is less viscous and flows more easily.
What makes magma explode?
The gasses dissolved in the magma (or the entry of water into the magma) cause the explosive behaviour.
What type of magma flows from Mount Rainier?
Mount Rainier primarily erupts andesitic magma, which is a type of intermediate magma that is thicker and more viscous than basaltic magma. Andesitic magma often leads to explosive eruptions due to its high gas content and tendency to trap pressure.
What makes a beard grow thicker?
Nothing.
