What else can I help you with?
Magma flows easily when it is low in?
silica content. High temperature and low silica content in magma allow for easier flow due to reduced viscosity. This type of magma often results in non-explosive volcanic eruptions with lava flows.
What type of magna has a low silica content?
Magma with low silica content is typically referred to as mafic magma. Mafic magma is characterized by its high temperature and low viscosity, which allows for the eruption of lava flows. This type of magma is commonly associated with basaltic rocks.
Do gases escape from a low silica magma easier than it does a high silica magma?
yes
If magma has high silica what will a volcano probably do?
high silica eruptions are generally explosive, giving rise to large abbounts of dust and may even result in pyroclastic flows. This happens because high silica melts are more viscous (thick) than low silica melts. If you see a nice river or fountain of lava, you can bet that it is relatively low in silica, probably a basalt.
What kind of eription is produced when basaltic lava that is low in silica flows from a volcan?
A quiet, non explosive eruption. Silica-high lava produces explosive eruptions.

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 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 is the behavior of lava with silica content being high and low?
Lava with high silica content tends to be more viscous and flow more slowly, leading to explosive eruptions. In contrast, lava with low silica content is less viscous and flows more easily, resulting in gentler, effusive eruptions.
How does water affect volcanoes?
Water can affect volcanoes in different ways. When water enters the magma chamber beneath a volcano, it can lower the melting point of the rock, making it easier for magma to form and leading to more explosive eruptions. Water can also mix with magma to create more viscous lava flows that can be more dangerous and create lahars (mudflows) when the volcano erupts. Additionally, interactions between water and volcanic gases can lead to the formation of acid rain and other environmental hazards.
What is the difference in silica content and viscosity between light-colored and dark-colored magma?
The lower the viscosity is the hotter the magma is and faster it flows.Higher the viscosity is the cooler it is and slower it flows down.
Does mt.st.helens have a high or low silica content?
Because Mount Rainier is a Strato Volcano it has both quiet and explosive eruptions. Explosive(pyroclastic) flows have a high silica level. Quiet have low silica levels. The more silica the thicker the magma.
What kind of lava is silica poor?
Silica-poor lava is called mafic lava. It is low in silica content and high in iron and magnesium, which makes it less viscous and more fluid compared to silica-rich lava. Mafic lava typically erupts at higher temperatures and flows more rapidly, resulting in the formation of basaltic rocks.
