Oxygen, the most abundant element in magma, comprises a little less than half the total, followed by silicon at just over one-quarter. The remaining elements make up the other one-quarter. Magmas derived from crustal material are dominated by oxygen, silicon, aluminum, sodium, and potassium.
What are the top two composition of magma?
The composition of the gases in magma are: Mostly H2O (water vapor) & some CO2 (carbon dioxide) Minor amounts of Sulfur, Chlorine, and Fluorine gases.
Which component of magma is the highest in value?
Explanation: The silica content in felsic magma is the greatest of all magma forms, ranging from 65 to 70%. As a result, felsic magma has the highest gas content and viscosity, as well as the lowest mean temperatures, ranging from 650 to 800 degrees Celsius (1202o and 1472o Fahrenheit).
