What are the two types of magma?
Felsic and mafic magma
Basic and acidic magma
What are the characteristics of mafic magma?
Crystallizes at a Very hot temperature (900-1200°C)
Is very fluid
Has low silica content (~50%)
contains magnesium and iron rich minerals
its volatiles gases are low
It produces flowing volcanoes: Lava flows
All of the Above
Which is more dense, mafic magma or felsic magma
Felsic
Mafic
What is an example of mafic magma?
Oceanic crust
Continental crust
What type of volcanoes does mafic magma create?
Shield and cinder cone volcanoes
calderas and shield volcanoes
What are the characteristics of felsic magma?
it crystallizes at a temperature that is less than 850°C
It is highly viscous
It has a high silica content
It contains felspar and silica rich minerals like quartz
Its volatile gasses may reach up to 15%
water and carbon dioxide are its main volatile gasses
Which is less dense, felsic magma or mafic magma?
