What affects the speed of lava flows?
The temperature and the silica content will both affect the viscosity of lave which will in turn affect the flow rate (whereby the lower the temperature and the higher the silica content, the higher the viscosity and the lower the flow rate).
What is the relationship between silicon content and the viscosity of magma?
Although other factors such as temperature and water content also affect the viscosity of magma, silica-rich magmas tend to be more viscous than silica-poor magmas in similar situations.
How does the coposition of the magma affect the temperature at which it solidifies?
The composition of the magma is very important for solidificatoin temperature. When it starts to cool, crystals of minerals begin to grow. If it has a low silica content - which means high melting point - the magma will solidify at high temeratures. If it has a high silica content - which means low melting point - it will solidify at lower temperatures.
What are 3 substances that affect the explosiveness of volcanic eruptions?
Amount of dissolved gasses in a liquid, the silica content, and the viscosity of the magma.
How does silica affect the shape of a volcano?
A high silica content of the magma will form tall, steep-sided, or cone-shaped mountains. A low silica content produces shield shaped or broad volcanoes.
What affects the speed of lava flows?
The temperature and the silica content will both affect the viscosity of lave which will in turn affect the flow rate (whereby the lower the temperature and the higher the silica content, the higher the viscosity and the lower the flow rate).
What factors affect magma's viscosity?
The two main factors that affect viscosity are temperature and silica content. Higher temperatures lower viscosity while higher silica content increases viscosity.
What is the relationship between silicon content and the viscosity of magma?
Although other factors such as temperature and water content also affect the viscosity of magma, silica-rich magmas tend to be more viscous than silica-poor magmas in similar situations.
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 does silica content?
Any metrial or thing which containts silica in it is call silica content..
What does silica content mean?
Any metrial or thing which containts silica in it is call silica content..
How does silica content affect igenous rocks?
It determines high silica or low silica. It will determine if it is sticky or not, or if it flows fast or slow. *high in silica~Sticky, and slow. Will not flow easily. *low in silica~Fact, not sticky. Will flow easily.
What is the behavior of lava with silica content being high and low?
Lava with high silica content will erupt explosively, if it has low silica content it will flow.
What is the silica content of Stromboli?
Stromboli has a 53 to 54% silica content on average.
