== == 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.

Why would felsic lava not produce a natural tunnel within itself as it cools?
Lava tubes formed from mafic lava form when the lava forms a crust over itself, creating a tube through which it can flow and later leave empty. Felsic lava forms a crust, but is too viscous to entirely flow out of it.
Which moves fast felsic lava or mafic lava?
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.
What is moving Lava?
Felsic magma.
Does paricutin mafic or felsic lava?
Paricutin erupted mafic lava.
Is mauna loa mafic or felsic?
The 1980 eruption of Mount St. Helens produced dacite, which has an intermediate-felsic composition.
Is felsic lava thick?
Felsic lava is a slower moving lava, with high silica content. Most felsic lava deposits as granite, granite, muscovite, and orthoclase.
Between mafic lava and felsic lava which flowsfaster?
Mafic lava is hotter than felsic lava and therefore flows faster.

What is moving Lava?
Felsic magma.
Where did felsic lava get its name?
The term felsic des derived from feldspar and silica, which are the primary components of felsic rock.
Does paricutin mafic or felsic lava?
Paricutin erupted mafic lava.
What type of magma does Mt.Tambora have?
felsic lava
What kind of lava is in Mt Vesuvius?
the type of lava from mt vesuvius is felsic lava in a pyroclstic explosion.
What is felsic lava identified by?
color and sulfer content
What is coolslow-moving lava called?
Felsic magma.
Does felsic lava create violent or quiet eruptions?
Felsic lava, due to its high viscosity and generally high gas content tends to produce violent eruptions.
