The magma of shield volcanoes is rich in?
They are rich in magnesium and iron.
What is shield volcanoes lava composed of?
TThe magma is composed of gas and is silica rich.
Why are volcanoes in the Andes so violent?
The volcanoes in the Andes are generally fed by very viscous, gas-rich magma. The gas is kept dissolved in the magma under enormous pressure. When the magma is close enough to the surface the lower pressure allows the gasses to come out of solution violently. This is what makes these eruptions explosive.
Volcanoes formed from silica-rich magma?
first its not a question so if volcanoes formed from magma it will be a igneous rock.search me up on roblox.com my account name is xxbrandon3
What types of materials are volcanoes like mt st helens made of?
Layers and layers of primarily felsic or intermediate-composition magma -- magma that is relatively rich in silica, sodium, aluminum, and potassium. These crystallize to form granitic rocks. These are the classic shapes of volcano that every school kid knows, known as stratovolcanoes or composite volcanoes.
The magma of shield volcanoes is rich in?
They are rich in magnesium and iron.
What is shield volcanoes lava composed of?
TThe magma is composed of gas and is silica rich.
Silica-rich magma erupts from the shield volcanoes giving them there broad flat shape?
False. The magma of shield volcanoes is silica-poor.
What is basalts crystal structure?
It is rich in iron and magnesium

How are volcanoes linked to agrcultural activity?
As the magma cools and sits over the years, it creates and gains very rich minerals that are extremely good for agriculture.

What properties of magma help to determine the type of eruptions?
The properties of magma that help to determine the type of eruption are the magma's viscosity and its silica content. Those volcanoes that exhibit massive eruptions have a high viscosity and high silica content.
What magma is silica-rich thick magma?
An acid magma or a granitic magma.

These are the classic shapes of volcano that every school kid knows, known as stratovolcanoes or composite volcanoes.
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 is Silica rich thick magma called?
The three types of magma, named for the rock they form are basaltic, rhyolitic and andesitic. Rhyolitic magma is rich in silica and water vapor.
