What else can I help you with?
This type of magma is thick moves slowly and does not flow well?
The type of magma you are referring to is called viscous magma. It is rich in silica and other minerals, making it thick and sticky. As a result, it does not flow easily and tends to form domes or plugs when it erupts.
What makes magma thicker?
If there is a high silica content in the magma, the eruption is usually more violent and explosive. Magma with a high silica content flows slower so pressure can build up and eventually erupt.
What is the difference in silica content and viscosity between light color 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.
What is the term used to describe igneous rocks or magma rich in Fe-Mg content and low in silica?
Mafic rocks or magma are rich in Fe-Mg content and low in silica. These rocks typically have dark colors and contain minerals such as olivine, pyroxene, and amphibole. Examples of mafic rocks include basalt and gabbro.
Igneous rocks that are dense and dark colored they form from magma that is rich in iron and magnesium and poor in silica?
These types of igneous rocks are commonly known as mafic rocks. They have a high density due to the presence of minerals like olivine, pyroxene, and amphibole, which are rich in iron and magnesium. Examples include basalt and gabbro.
What are silica rich and thick magma is what?
Silica is sand dust.
What magma is silica-rich thick magma?
An acid magma or a granitic magma.
What effect does silicia content have on the characteristics of magma?
Silica-rich magma is much more thick and viscous.
What kind of magma is silica-rich thick magma?
Silica-rich thick magma is typically classified as either dacitic or rhyolitic magma. These magmas have higher silica content, making them more viscous and able to trap gas bubbles. They often erupt explosively due to the high pressure build-up caused by the thick magma.

Why is silica rich magma associated with explosive eruptions?
Silica-rich magma has high viscosity, which can trap gas bubbles. When pressure builds up, the gas can cause explosive eruptions as it tries to escape through the thick magma. The high silica content also promotes the formation of explosive pyroclastic materials during an eruption.
What magma is rich in feldspars and silica?
no its the least silica rich of granitic and andesitic magma.
What kind of silica do strato volcanos have?
silica-rich magma
What type of magma produces violent reaction?
Acidic lava is very viscous, and thus will harden and block the vent. The magma will force its way out through the vent and create a violent explosion.
What color is silica rich magma?
red or scarlet
Is granitic magma very silica-rich.?
Yes
Why silica rich magma is more dangerous than iron rich magma?
The silica-rich magma, also called felsic magma, is more viscous than iron-rich or mafic magma. This means resists flow more (just as syrup is more viscous than water). The high viscosity means that the felsic magma can trap more gasses, leading to explosive eruptions, rather than effusive ones.
