A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.

Does paricutin mafic or felsic lava?
Paricutin erupted mafic lava.
What happens when mafic lava cools down too fast?
If lava cools too fast, whether it is mafic, felsic, or intermediate crystals fail to develop and volcanic glass forms.
Do cinder cones erupt felsic or mafic lava?
Composite volcanoes can erupt both mafic and felsic material, but intermediate material is the most common.
Is mafic or felsic lava produced in mt fuji?
mafic lava is the KIND of lava produced in mount (mt) Fuji.
Is mauna loa mafic or felsic?
The 1980 eruption of Mount St. Helens produced dacite, which has an intermediate-felsic composition.
Between mafic lava and felsic lava which flowsfaster?
Mafic lava is hotter than felsic lava and therefore flows faster.

Where does felsic lava form at?
== == Felsic lava has a higher silica content than mafic lava. Felsic lava is slower moving (high viscosity) than the less viscous mafic lava. Mafic lava is higher in dark minerals and higher in the elements iron and magnesium.
How does mafic lava turn into felsic lava?
Mafic lava, before cooling, has a low viscosity, in comparison to felsic lava, due to the lower silica content in mafic magma. Water and other volatiles can more easily and gradually escape from mafic lava, so eruptions of volcanoes made of mafic lavas are less explosively violent than felsic lava eruptions. Most mafic lava volcanoes are oceanic volcanoes, like Hawaii.Felsic is a term used in geology to refer to silicate minerals, magmas, and rocks which are enriched in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. The term combines the words "feldspar" and "silica." Felsic minerals are usually light in color and have specific gravities less than 3. Common felsic minerals include quartz, muscovite, orthoclase, and the sodium-rich plagioclase feldspars. The most common felsic rock is granite. On the opposite side of the rock spectrum are the iron and magnesium-rich mafic and ultramafic minerals and rocks.There are a few means by which felsic magma can be generated from mafic magma. Felsic materials have lower melting points than mafic materials and so will tend to melt first during partial melting. This can shift composition to something more felsic. Another process is called fractional crystalization. Here, more mafic material crystallizes and settles out of a magma chamber, making the remaining molten material more felsic. Finally, as mafic magma moves though continental crust, which is generally felsic in composition, it incorporates some of the rock and becomes more felsic.
What type of lava forms mt hood?
Mafic magma and Felsic magma.
